The Robonaut Josh Kuhn

What is Robonaut?  A dexterous, humanoid robot  Developed at NASA’s Johnson Space Center (JSC) with support from GM  Designed to work side-by- side with humans  4 current Robonauts

Equipment-Robotnaut 2 Specs  Weight:150 kg  350+ sensors  4 cameras (stereo vision) + infrared camera for depth perception  38 PowerPC processors  Height: 1.01 m (waist to head)  Shoulder width: 0.78 m  Modular

Equipment-Robotnaut 2 Specs  Dexterous fingers: grasping force of 2.3 kg  Arm reach of 0.81 m  Arms can hold 20 lbs  Performs autonomous tasks and can be controlled remotely by humans  Made of primarily aluminum and some steel

Dexterity  Can use same tools as astronauts  Series elastic joint technology  Extended finger and thumb travel  Miniaturized 6-axis load cells  Redundant force sensing  Ultra-high speed joint controllers

Application  Interacts and assists astronauts  Performs simple, repetitive, and dangerous tasks

Johnson Space Center  Developed by the Robotic Systems Technology Branch  Other projects:  Space Exploration Vehicle (SEV)  Spider  X1 – Exoskeleton  Centaur 1 & 2

Mobility  Centaur 1 & 2  Rovers created to carry Robonaut and other payloads  “Space legs”  Segwey  ISS robotic arm  Future lower bodies for Robonaut include zero- gravity climbing legs for EVAs

Centaur 2  Centaur 2’s unique characteristics  Force controlled suspension  Thermal/dust isolation  Crab steering  Body articulation  In-hub wheel actuation

Robonaut in Space!  Robonaut 2 launched up to the ISS on February 24th, 2011, fulfilling a 15 year dream to put a humanoid robot into space.

Limitations/Costs  $2.5 million  Limited mobility  Limited weight bearing capacity  Limited autonomous ability

Conclusion  First Humanoid Robot in space  Additional phases for added mobility initiated  Modular parts to be sent to ISS  One of the most dexterous robots of its kind  Can do things humans cannot (range of motion, precision, repeatability)
