FIRST robotics competition leaps onto new CompactRIO controller
The new flexibility and processing power means that robots should be better able to handle the complex control and signal-processing algorithms required to operate autonomouslyâ''that is, without being â''drivenâ'' from the sidelines by handlers;
in previous competitions, robots were required to spend 15 seconds operating autonomously, but one-third of the teams didnâ''t attempt to score during this period.
The souped-up processing power also means that the robots will be able to handle more complex image data in real time, identifying shapes or doing optical character recognitionâ''they will be robots that can read.
Lego Mindstorms is a hardware software platform produced by Lego for the development of programmable robots based on Lego building blocks.
Each version of the system includes an intelligent brick computer that controls the system, a set of modular sensors and motors, and Lego parts from the Technic line to create the mechanical systems.
A second prototype series was developed in the mid-1990s before the final device was released in 1998. The first visual programming environment was called LEGOsheets, since it was created by the University of Colorado in 1994 based on AgentSheets.
The brick is programmed by uploading a program (written in one of several available programming languages) from a Windows or Mac computer to the brick's RAM via a special infrared (IR) interface.
In addition to the IR port, the system includes three sensor input ports and three motor output ports (which can also be used to drive other electrical devices such as lamps and so forth).
A built-in LCD can display the battery level, the status of the input/output ports, which program is selected or running, and other information. Version 1.0 RCX bricks feature a power adapter jack to allow continuous operation instead of the limited operation time when using batteries.
The IR interface on the RCX is able to communicate with Spybots, Scout Bricks, Lego Train, and the NXT (using a third-party infrared link sensor.) The RCX 1.0 IR receiver carrier frequency is 38.5 kHz, while the RCX 2.0 IR carrier frequency is 76 kHz.
The serial tower works normally under 64-bit Windows 7 using a third-party USB-to-serial adapter.[contradictory] All versions of the RCX have a unique number printed on it, necessary for technical support and used as the ID number of the RCX for your Lego Mindstorms account on the now-defunct Lego Mindstorms RCX website.
The first programmable Lego product was released in 1986. In 1987, Dacta released an Apple IIe interface card set and an IBM-PC-compatible ISA interface card set, each coming with a ribbon cable.
The control panel included six non-reversible 4.5V output ports, three reversible 4.5V output ports (each using the power lines from their two adjacent non-reversible ports), two 4.5V input ports, and one continuous 4.5V output port.
It featured three output ports and manual control, and it was only capable of storing linear sequences of manual input plus timing information.
The control lab was a datalogger, which featured four passive input ports, four active input ports, eight controllable 9V output ports, and one continuous output port.
The control panel connected to a computer using a serial-port with a specially designed adapter cable and a supplied computer-program allowed the user to conditionally program the outputs.
The brick shares many, especially software, features with the RCX but differs in appearance and technical specifications: one output (plus two built-in) and four sensors.
It talks the same protocol as the RCX but cannot communicate directly to it (due to IR vs RF) but with a repeater (a computer with 2 serial ports and a simple program) they can communicate indirectly.
Lego also released a blue computer called the Scout, which has 2 sensor ports, 2 motor ports (plus one extra if linked with a Micro Scout using a fiber optic cable), and a built in light sensor, but no PC interface.
The analog-to-digital converters used in the Scout only have a resolution of 8 bits in contrast to the 10-bit converters of the RCX. There was a plan for Lego to create a booster set that allows you to program the Scout from a computer with a software such as RCX code.
Lego Mindstorms NXT is a programmable robotics kit released by Lego in July 2006, replacing the first-generation LEGO Mindstorms kit. The kit consists of 577 pieces, including: 3 servo motors, 4 sensors (ultrasonic, sound, touch, and light), 7 connection cables, a USB interface cable, and the NXT Intelligent Brick.
Mindstorms kits are also sold and used as an educational tool, originally through a partnership between Lego and the MIT Media Laboratory. The educational version of the products is called Lego Mindstorms for Schools, and comes with the ROBOLAB GUI-based programming software, developed at Tufts University using the National Instruments LabVIEW as an engine.
In addition, the shipped software can be replaced with third party firmware and/or programming languages, including some of the most popular ones used by professionals in the embedded systems industry, like Java and C.
The retail version was designed for more of a home/toy use vs the educator model was designed to support deeper learning with extra resources and pieces to do so.
There is a strong community of professionals and hobbyists of all ages involved in the sharing of designs, programming techniques, creating third-party software and hardware, and contributing of other ideas associated with Lego Mindstorms.
A robot is a machine—especially one programmable by a computer— capable of carrying out a complex series of actions automatically. Robots can be guided by an external control device or the control may be embedded within.
It was sold to General Motors in 1961 where it was used to lift pieces of hot metal from die casting machines at the Inland Fisher Guide Plant in the West Trenton section of Ewing Township, New Jersey. Robots have replaced humans in performing repetitive and dangerous tasks which humans prefer not to do, or are unable to do because of size limitations, or which take place in extreme environments such as outer space or the bottom of the sea.
The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots. There is no consensus on which machines qualify as robots but there is general agreement among experts, and the public, that robots tend to possess some or all of the following abilities and functions: accept electronic programming, process data or physical perceptions electronically, operate autonomously to some degree, move around, operate physical parts of itself or physical processes, sense and manipulate their environment, and exhibit intelligent behavior, especially behavior which mimics humans or other animals. Closely related to the concept of a robot is the field of Synthetic Biology, which studies entities whose nature is more comparable to beings than to machines.
Early descriptions of automata include the artificial doves of Archytas, the artificial birds of Mozi and Lu Ban, a 'speaking' automaton by Hero of Alexandria, a washstand automaton by Philo of Byzantium, and a human automaton described in the Lie Zi. Many ancient mythologies, and most modern religions include artificial people, such as the mechanical servants built by the Greek god Hephaestus (Vulcan to the Romans), the clay golems of Jewish legend and clay giants of Norse legend, and Galatea, the mythical statue of Pygmalion that came to life.
Hero of Alexandria (10–70 AD), a Greek mathematician and inventor, created numerous user-configurable automated devices, and described machines powered by air pressure, steam and water. The 11th century Lokapannatti tells of how the Buddha's relics were protected by mechanical robots (bhuta vahana yanta), from the kingdom of Roma visaya (Rome);
Yan Shi proudly presented the king with a life-size, human-shaped figure of his mechanical 'handiwork' made of leather, wood, and artificial organs. There are also accounts of flying automata in the Han Fei Zi and other texts, which attributes the 5th century BC Mohist philosopher Mozi and his contemporary Lu Ban with the invention of artificial wooden birds (ma yuan) that could successfully fly. In 1066, the Chinese inventor Su Song built a water clock in the form of a tower which featured mechanical figurines which chimed the hours.
The drummer could be made to play different rhythms and different drum patterns by moving the pegs to different locations. Samarangana Sutradhara, a Sanskrit treatise by Bhoja (11th century), includes a chapter about the construction of mechanical contrivances (automata), including mechanical bees and birds, fountains shaped like humans and animals, and male and female dolls that refilled oil lamps, danced, played instruments, and re-enacted scenes from Hindu mythology. In Renaissance Italy, Leonardo da Vinci (1452–1519) sketched plans for a humanoid robot around 1495.
The mechanical duck could flap its wings, crane its neck, and swallow food from the exhibitor's hand, and it gave the illusion of digesting its food by excreting matter stored in a hidden compartment. Remotely operated vehicles were demonstrated in the late 19th century in the form of several types of remotely controlled torpedoes.
The early 1870s saw remotely controlled torpedoes by John Ericsson (pneumatic), John Louis Lay (electric wire guided), and Victor von Scheliha (electric wire guided). The Brennan torpedo, invented by Louis Brennan in 1877 was powered by two contra-rotating propellors that were spun by rapidly pulling out wires from drums wound inside the torpedo.
Differential speed on the wires connected to the shore station allowed the torpedo to be guided to its target, making it 'the world's first practical guided missile'. In 1897 the British inventor Ernest Wilson was granted a patent for a torpedo remotely controlled by 'Hertzian' (radio) waves and in 1898 Nikola Tesla publicly demonstrated a wireless-controlled torpedo that he hoped to sell to the US Navy. Archibald Low, known as the 'father of radio guidance systems' for his pioneering work on guided rockets and planes during the First World War.
However, Josef Čapek was named by his brother Karel as the true inventor of the term robot. The word 'robot' itself was not new, having been in Slavic language as robota (forced laborer), a term which classified those peasants obligated to compulsory service under the feudal system widespread in 19th century Europe (see: Robot Patent). Čapek's fictional story postulated the technological creation of artificial human bodies without souls, and the old theme of the feudal robota class eloquently fit the imagination of a new class of manufactured, artificial workers.
In 1939, the humanoid robot known as Elektro was debuted at the 1939 New York World's Fair. Seven feet tall (2.1 m) and weighing 265 pounds (120.2 kg), it could walk by voice command, speak about 700 words (using a 78-rpm record player), smoke cigarettes, blow up balloons, and move its head and arms.
This ultimately laid the foundations of the modern robotics industry. Devol sold the first Unimate to General Motors in 1960, and it was installed in 1961 in a plant in Trenton, New Jersey to lift hot pieces of metal from a die casting machine and stack them. Devol's patent for the first digitally operated programmable robotic arm represents the foundation of the modern robotics industry. The first palletizing robot was introduced in 1963 by the Fuji Yusoki Kogyo Company. In 1973, a robot with six electromechanically driven axes was patented by KUKA robotics in Germany, and the programmable universal manipulation arm was invented by Victor Scheinman in 1976, and the design was sold to Unimation.
The International Organization for Standardization gives a definition of a manipulating industrial robot in ISO 8373: 'an automatically controlled, reprogrammable, multipurpose, manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications.' This definition is used by the International Federation of Robotics, the European Robotics Research Network (EURON) and many national standards committees. Most commonly industrial robots are fixed robotic arms and manipulators used primarily for production and distribution of goods.
Because modular robots of the same architecture type are composed of modules that compose different modular robots, a snake-arm robot can combine with another to form a dual or quadra-arm robot, or can split into several mobile robots, and mobile robots can split into multiple smaller ones, or combine with others into a larger or different one.
Intended for sale to small businesses, they are promoted as the robotic analogue of the personal computer. As of May 2014[update], 190 companies in the US have bought Baxters and they are being used commercially in the UK. Roughly half of all the robots in the world are in Asia, 32% in Europe, and 16% in North America, 1% in Australasia and 1% in Africa. 40% of all the robots in the world are in Japan, making Japan the country with the highest number of robots.
As robots have become more advanced and sophisticated, experts and academics have increasingly explored the questions of what ethics might govern robots' behavior, and whether robots might be able to claim any kind of social, cultural, ethical or legal rights. One scientific team has said that it is possible that a robot brain will exist by 2019. Others predict robot intelligence breakthroughs by 2050. Recent advances have made robotic behavior more sophisticated. The social impact of intelligent robots is subject of a 2010 documentary film called Plug
They noted that self-awareness as depicted in science-fiction is probably unlikely, but that there were other potential hazards and pitfalls. Various media sources and scientific groups have noted separate trends in differing areas which might together result in greater robotic functionalities and autonomy, and which pose some inherent concerns. In 2015, the Nao alderen robots were shown to have a capability for a degree of self-awareness.
Researchers at the Rensselaer Polytechnic Institute AI and Reasoning Lab in New York conducted an experiment where a robot became aware of itself, and corrected its answer to a question once it had realised this. Some experts and academics have questioned the use of robots for military combat, especially when such robots are given some degree of autonomous functions. There are also concerns about technology which might allow some armed robots to be controlled mainly by other robots. The US Navy has funded a report which indicates that, as military robots become more complex, there should be greater attention to implications of their ability to make autonomous decisions. One researcher states that autonomous robots might be more humane, as they could make decisions more effectively.
However, other experts question this. One robot in particular, the EATR, has generated public concerns over its fuel source, as it can continually refuel itself using organic substances. Although the engine for the EATR is designed to run on biomass and vegetation specifically selected by its sensors, which it can find on battlefields or other local environments, the project has stated that chicken fat can also be used. Manuel De Landa has noted that 'smart missiles' and autonomous bombs equipped with artificial perception can be considered robots, as they make some of their decisions autonomously.
Mass-produced printed circuit boards (PCBs) are almost exclusively manufactured by pick-and-place robots, typically with SCARA manipulators, which remove tiny electronic components from strips or trays, and place them on to PCBs with great accuracy. Such robots can place hundreds of thousands of components per hour, far out-performing a human in speed, accuracy, and reliability. Mobile robots, following markers or wires in the floor, or using vision or lasers, are used to transport goods around large facilities, such as warehouses, container ports, or hospitals. Limited to tasks that could be accurately defined and had to be performed the same way every time.
The job may be boring, such as domestic cleaning, or dangerous, such as exploring inside a volcano. Other jobs are physically inaccessible, such as exploring another planet, cleaning the inside of a long pipe, or performing laparoscopic surgery. Almost every unmanned space probe ever launched was a robot. Some were launched in the 1960s with very limited abilities, but their ability to fly and land (in the case of Luna 9) is an indication of their status as a robot.
For instance, a laparoscopic surgery robot allows the surgeon to work inside a human patient on a relatively small scale compared to open surgery, significantly shortening recovery time. They can also be used to avoid exposing workers to the hazardous and tight spaces such as in duct cleaning.
These pilotless drones can search terrain and fire on targets. Hundreds of robots such as iRobot's Packbot and the Foster-Miller TALON are being used in Iraq and Afghanistan by the U.S. military to defuse roadside bombs or improvised explosive devices (IEDs) in an activity known as explosive ordnance disposal (EOD). Robots are used to automate picking fruit on orchards at a cost lower than that of human pickers.
UCAVs are being designed such as the BAE Systems Mantis which would have the ability to fly themselves, to pick their own course and target, and to make most decisions on their own. The BAE Taranis is a UCAV built by Great Britain which can fly across continents without a pilot and has new means to avoid detection. Flight trials are expected to begin in 2011. The AAAI has studied this topic in depth and its president has commissioned a study to look at this issue. Some have suggested a need to build 'Friendly AI', meaning that the advances which are already occurring with AI should also include an effort to make AI intrinsically friendly and humane. Several such measures reportedly already exist, with robot-heavy countries such as Japan and South Korea having begun to pass regulations requiring robots to be equipped with safety systems, and possibly sets of 'laws' akin to Asimov's Three Laws of Robotics. An official report was issued in 2009 by the Japanese government's Robot Industry Policy Committee. Chinese officials and researchers have issued a report suggesting a set of ethical rules, and a set of new legal guidelines referred to as 'Robot Legal Studies.' Some concern has been expressed over a possible occurrence of robots telling apparent falsehoods. Mining robots are designed to solve a number of problems currently facing the mining industry, including skills shortages, improving productivity from declining ore grades, and achieving environmental targets.
One of the world's largest mining corporations, Rio Tinto, has recently expanded its autonomous truck fleet to the world's largest, consisting of 150 autonomous Komatsu trucks, operating in Western Australia. Similarly, BHP has announced the expansion of its autonomous drill fleet to the world's largest, 21 autonomous Atlas Copco drills. Drilling, longwall and rockbreaking machines are now also available as autonomous robots. The Atlas Copco Rig Control System can autonomously execute a drilling plan on a drilling rig, moving the rig into position using GPS, set up the drill rig and drill down to specified depths. Similarly, the Transmin Rocklogic system can automatically plan a path to position a rockbreaker at a selected destination. These systems greatly enhance the safety and efficiency of mining operations.
The population is aging in many countries, especially Japan, meaning that there are increasing numbers of elderly people to care for, but relatively fewer young people to care for them. Humans make the best carers, but where they are unavailable, robots are gradually being introduced. FRIEND is a semi-autonomous robot designed to support disabled and elderly people in their daily life activities, like preparing and serving a meal.
Algorithms have been designed in case any such robots become a reality. Robots with silicone bodies and flexible actuators (air muscles, electroactive polymers, and ferrofluids) look and feel different from robots with rigid skeletons, and can have different behaviors. Inspired by colonies of insects such as ants and bees, researchers are modeling the behavior of swarms of thousands of tiny robots which together perform a useful task, such as finding something hidden, cleaning, or spying.
Robotic forces allow simulating the mechanical properties of 'virtual' objects, which users can experience through their sense of touch. Robotic characters, androids (artificial men/women) or gynoids (artificial women), and cyborgs (also 'bionic men/women', or humans with significant mechanical enhancements) have become a staple of science fiction.
Possibly the most prolific author of the twentieth century was Isaac Asimov (1920–1992) who published over five-hundred books. Asimov is probably best remembered for his science-fiction stories and especially those about robots, where he placed robots and their interaction with society at the center of many of his works. Asimov carefully considered the problem of the ideal set of instructions robots might be given in order to lower the risk to humans, and arrived at his Three Laws of Robotics: a robot may not injure a human being or, through inaction, allow a human being to come to harm;
