Articulated Inspection Arm

Remote handling technology, especially the remote inspection system for the plasma facing components (PFCs) without breaking the condition of the VV, has been identified as one of the most important tasks for the maintenance of EAST/WEST.

There is a RH team in ASIPP dedicated to the multi-joint inspection robot. The Articulated Inspection Arm robot (AIA) is one of the three cooperative projects launched by Joint Research Laboratory which had been built by ASIPP from China and CEA from France on Jul 3, 2013. AIA is an 10m long multi-link robot with a payload up to 25 kg operable between plasma under tokamak conditioning environment, consists of six modules made in titanium and several end-effectors with the standard interface. It is proposed to inspect the surface of PFCs to know the performance of first wall, such as erosion and desquamation during plasma operation campaign. With an embedded viewing system, AIA has been successfully developed accurate visual inspection feasibility inside the vacuum vessel of Tore Supra tokamak. Different functions can be implemented with different end-effectors to be plugged at the last joint of the robot.

The AIA robot shall be redesign for assembling/disassembling the graphite tile according to the maintenance requirement of the EAST. Leak detection of first wall based on helium sniffing, laser compact system for carbon co-deposited layers characterizations or treatments and gripper structure for fragments are also considered for demonstration in EAST tokamak.
