Fetch Robotics Fetch

A research mobile manipulator from Fetch Robotics, combining a lifting torso and a 7-DoF arm.

Fetch is the research-grade mobile manipulator from the American company Fetch Robotics: a differential-drive base, a torso that lifts up and down, a head that pans and tilts, plus a backdrivable 7-DoF robot arm and a parallel two-finger gripper. The arm uses harmonic-drive reducers paired with frameless motors and has about a 6 kg payload; the base carries a SICK lidar, the head has a depth camera, and it runs ROS. In the mid-to-late 2010s it was a common platform for US universities doing mobile manipulation, grasping, and navigation research, occupying a role similar to the earlier PR2. The company's main business was actually warehouse AMRs, and it was acquired by Zebra Technologies in 2021: Zebra paid about $290 million for the 95% of the company it didn't already own, valuing it at roughly $305 million overall.

ExampleA research group runs MoveIt on a Fetch for grasp planning, having it pull a specified item off a shelf and drive it over to set down on a table.
