Motiv’s Custom Robotics

Mars 2020 Perseverance Rover’s Primary Robotic Arm

At the front of NASA’s Mars 2020 Perseverance rover is a seven-foot long arm with five joints. It carries some of the mission’s most critical tools for analyzing and sampling the Martian surface. To design and build this critical piece of robotics, NASA turned to Motiv Space Systems.


A seven-foot (2.1 meter) long five-DOF robotic arm that carries some of the rover’s most critical science instruments. The arm’s turret holds the key instruments in Perseverance’s search for signs of life including SHERLOC and WATSON, PIXL, GDRT (Gaseous Dust Removal Tool), Ground Contact Sensor, the Drill.
