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.

[1] In the early morning of February 4, 2011, Dextre completed its first official assignment which consisted of unpacking two pieces for Kounotori 2 while the on-board crew was sleeping.

The OTCM has built-in grasping jaws, a retractable socket drive, a monochrome TV camera, lights, and an umbilical connector that can provide power, data, and video to/from a payload.

The lower body of Dextre has a pair of orientable colour TV cameras with lights, a platform for stowing ORUs, and a tool holster.

In 2013 the H-II Transport Vehicle brought the RRM On-orbit Transfer Cage (ROTC), which is a sliding table within the Japanese airlock platform from which to retrieve and subsequently install new hardware.

It includes a mass spectrometer and an ion vacuum pressure gauge to detect leaks of ammonia, one of the coolants used on the International Space Station.

Examples of items successfully R&R'd include RPCMs, an external camera, a Pump Flow Control Subassembly, and a Main Bus Switching Unit.

In early August 2004 NASA declared its intention to use Dextre (or a close copy of it) as the robotic component for the Hubble Space Telescope rescue mission.

[16] Dextre was also featured in the new $5 Canadian Polymer bank note together with Canadarm2, which Commander Chris Hadfield helped reveal aboard the International Space Station.
