MakerWorks Lab is a maker space in Malad East, Mumbai, teaching robotics, Physical AI and hands-on hardware engineering with platforms such as LeRobot Arms, Reachy Mini and OpenDuck Mini V2.
A local web app by Ajay Ummadi that runs, monitors and visualizes teleoperation of two SO-101 robot arms: a hand-held leader arm controls a follower arm in real time. It builds on LeRobot and includes live telemetry, session recording, a calibration manager and a 3D digital twin. It is a separate add-on and not endorsed by LeRobot.
Wired, passive open-ear earphones designed by Ajay Ummadi in a single parametric Blender Python script around a salvaged earphone driver. The pod sits in front of the ear canal with an arm over the ear. Both ears are printed and worn; sound quality and the cable-reel case are not yet tested.
