SpaceMouse Enables Training Of Desk-Scale Robot Arm

Hardware hacker Nikodem Bartnik used a 3Dconnexion SpaceMouse to teleoperate a Seeed Studio SO-ARM101 robotic arm, recording 30 training episodes of a LEGO pick-and-place task. After mapping SpaceMouse motions directly to joints and forking Hugging Face's Lerobot library, he migrated from an NVIDIA Jetson Orin Nano to a desktop and trained an ACT policy on an NVIDIA RTX 4090 in about 45 minutes, producing autonomous but less fluid pick-and-place behavior.
