ALPHA-α is a low-cost bimanual leader-follower teleoperation platform built from four 6-DOF OpenMANIPULATOR SARA arms (two leaders, two followers). It uses four-channel bilateral control to teleoperate with both position and force feedback, enabling force-aware imitation learning (Bi-ACT) for everyday two-handed manipulation. Developed at The University of Osaka as an open, roughly-half-the-cost alternative to ALOHA-class rigs.
