A new method for type synthesis of non-holonomic underactuated parallel mechanisms

Every year, approximately 100 satellites are launched into space to monitor activity on Earth and enable services such as communications or GPS systems.

The term 'on-orbit servicing' refers to a variety of operations aimed at maintaining space systems in orbit, which can entail repairs, assembly, refueling and upgrading spacecraft after their deployment.

'The underactuated non-holonomic parallel mechanism is a new direction of parallel space robotics, with small volume, light weight, low cost, low energy consumption, and high flexibility,' the researchers wrote in their paper.

One key issue in the development of parallel mechanisms is type synthesis, which involves finding all possible types of parallel mechanisms generating a motion of the moving platform with a specified degree of freedom (DOF) or motion pattern.

'This paper is devoted to type synthesis of underactuated parallel mechanisms with spherical motion pattern accompanied by the generation of the non-holonomic spherical pairs in parallel mechanisms with spherical motion pattern.'
