The Augmented Reality assisted assembly training (ARAAT) is an effective and low-cost way in motor and electronic industry.

In ARAAT, assembly operations are the processes which mainly use the AR device to recognize the gestures and match the virtual workpieces to the hand based on the consistency of time and space.

According to the 2D and 3D features of the action unit, a scorer trained by the samples of specific actions gives the optimal label of each frame to recognize the action.

Nvidia developer blog

NVIDIA announced the Jetson Nano Developer Kit at the 2019 NVIDIA GPU Technology Conference (GTC), a $99 computer available now for embedded designers, researchers, and DIY makers, delivering the power of modern AI in a compact, easy-to-use platform with full software programmability.

The newly released JetPack 4.2 SDK provides a complete desktop Linux environment for Jetson Nano based on Ubuntu 18.04 with accelerated graphics, support for NVIDIA CUDA Toolkit 10.0, and libraries such as cuDNN 7.3 and TensorRT 5.The SDK also includes the ability to natively install popular open source Machine Learning (ML) frameworks such as TensorFlow, PyTorch, Caffe, Keras, and MXNet, along with frameworks for computer vision and robotics development like OpenCV and ROS.

The Jetson Nano Developer Kit fits in a footprint of just 80x100mm and features four high-speed USB 3.0 ports, MIPI CSI-2 camera connector, HDMI 2.0 and DisplayPort 1.3, Gigabit Ethernet, M.2 Key-E module, MicroSD card slot, and 40-pin GPIO header.

The Jetson Nano compute module is 45x70mm and will be shipping starting in June 2019 for $129 (in 1000-unit volume) for embedded designers to integrate into production systems. The production compute module will include 16GB eMMC onboard storage and enhanced I/O with PCIe Gen2 x4/x2/x1, MIPI DSI, additional GPIO, and 12 lanes of MIPI CSI-2 for connecting up to three x4 cameras or up to four cameras in x4/x2 configurations.

These networks can be used to build autonomous machines and complex AI systems by implementing robust capabilities such as image recognition, object detection and localization, pose estimation, semantic segmentation, video enhancement, and intelligent analytics.

Table 2 provides full results, including the performance of other platforms like the Raspberry Pi 3, Intel Neural Compute Stick 2, and Google Edge TPU Coral Dev Board: DNR (did not run) results occurred frequently due to limited memory capacity, unsupported network layers, or hardware/software limitations.

Fixed-function neural network accelerators often support a relatively narrow set of use-cases, with dedicated layer operations supported in hardware, with network weights and activations required to fit in limited on-chip caches to avoid significant data transfer penalties.

Jetson Nano’s flexible software and full framework support, memory capacity, and unified memory subsystem, make it able to run a myriad of different networks up to full HD resolution, including variable batch sizes on multiple sensor streams concurrently.

The video below shows Jetson Nano performing object detection on eight 1080p30 streams simultaneously with a ResNet-based model running at full resolution and a throughput of 500 megapixels per second (MP/s).

The project provides you with easy to learn examples through Jupyter notebooks on how to write Python code to control the motors, train JetBot to detect obstacles, follow objects like people and household objects, and train JetBot to follow paths around the floor.

Developers who want to try training their own models can follow the full “Two Days to a Demo” tutorial, which covers the re-training and customization of image classification, object detection, and semantic segmentation models with transfer learning.

Table 3 highlights some initial results of transfer learning from the Two Days to a Demo tutorial with PyTorch using Jetson Nano for training Alexnet and ResNet-18 on a 200,000 image, 22.5GB subset of ImageNet: The time per epoch is how long it takes to make a full pass through the training dataset of 200K images.
