As the other poster has pointed out, the Hubble servicing robot will be built by the Canadian company MD Robotics, which has a long history of successful space robotics in the form of the SRMS on Shuttle and the SSRMS and MBS on ISS.
The Dextrous Robot portion of the Hubble servicing robot (the other portion the Grapple Arm - a mini-SRMS) has already been developed to Class A manned spaceflight standards for the ISS and is most of the way throught it's final integration at the element and end-to-end levels.
A terrestrial development version of the DR has already demonstrated it's ability to perform the mission tasks on the full Hubble mock-up at Goddard. It was these demonstrations that convinced a skeptical NASA community that a robotic mission was not only possible, but actually has a high probability of success.
