Overview

A museum exhibit developed at CMU ETC where visitors control a real 6-axis collaborative robot arm using their own body movements. A body tracking system maps the visitor’s arm pose to the robot’s end-effector, letting them reach into a physical claw machine and grab stuffed animals and prizes — like being a giant robot yourself.

My Role

Co-developed with John Balash at CMU ETC. Led body tracking integration, robot arm control pipeline, and safety/collision systems for public-facing museum deployment.

Key Features

  • Real-time human body tracking mapped to 6-DOF robot arm
  • Collaborative robot (cobot) with compliant force control for safety
  • Adaptive claw end-effector for grabbing varied prize shapes
  • Designed for unattended public museum use with robust safety bounds
  • Portable setup for traveling exhibit deployment
