CubEArm

Performing complex IOS, ADR, and IOM operations requires advanced, autonomous robotic systems capable of performing docking, docking, grabbing, and manipulation tasks on objects of different shapes, sizes, and materials. These actions are severely limited by the current difficulties in establishing a physical interface with satellites or debris in a hostile environment such as space. 
There is also a need to develop robotic arms with relatively large working space despite the small footprint in the folded configuration, which must be compatible with the size of the cubesat. The required dexterity, on the other hand, may vary significantly with the mission purpose and maneuvering capability of the CubeSat.

This solution is highly innovative because it will make it possible to grasp spatial objects with a variety of shapes, surfaces, and materials (even those not prepared for gripping), unlike what is possible today with traditional gripping organs with two- or multi-finger gripper mechanisms or other types of automated gripping interfaces. The proposed system involves the implementation of a proprietary gripper device from Adaptronics that becomes adhesive on command by electrostatic forces and has integrated proximity sensor and target object contact capabilities. Such a gripper will be installed on a robotic arm developed by DIMEAS of the Polytechnic University of Turin, designed for a module of 1 U and controlled through electronics developed by the company Axist.

The most relevant impact for the entire group involved in the project (Adaptronics and Axist primarily, and the Politecnico di Torino secondarily) is to accelerate the development of enabling technologies for in-orbit service operations such as space logistics and the possibility of accrediting themselves as credible players with solid know-how for the development of robotic gripping systems for space applications. The presence in the territory of industrial players capable of proposing themselves for the development of space systems has a potential spillover effect on the territory in terms of generating qualified job opportunities, both directly at the companies that operate themselves and at the subcontracting companies that can be involved from time to time to respond to market demands. Moreover, the development of such complex capabilities as robotic gripping and manipulation have significant strategic importance in the space field, and will allow for increased Italian and European competitiveness and autonomy in on-orbit operations.
