Overview
Dextre, also known as the Special Purpose Dexterous Manipulator (SPDM), is a two-armed robot, or telemanipulator, which is part of the Mobile Servicing System on the International Space Station (ISS), and does repairs that would otherwise require astronauts to do spacewalks. It was launched on March 11, 2008, on the mission STS-123. Dextre is designed to handle and complete orbital replacement units, making it capable of carrying spares and conducting complex tasks in orbit.
Flagship features
- Dextre is a 15-axis robotic arm system (two 7-joint arms plus a waist rotation joint) for space-based operations
- It is mounted on the Mobile Servicing System (MSS) on the International Space Station, created by the Canadian Space Agency
- Payload capacity is 600 kg per arm (at the end of the arm), though microgravity reduces the effective mechanical load
- The robot's primary role is external station maintenance, inspection, and experimental satellite refuelling
- It uses a 'force-moment sensor' at the end effector for fine manipulation
- Dextre was launched in 2008 on the Space Shuttle Endeavour (STS-123)

For the B2B database, it is an industrial arm designed specifically for space operations.
