Robotic Performance Platform

Pandemonium

Pandemonium is a multimedia performance by artist Michelle Lopez, commissioned for the Franklin Institute's Fels Planetarium. I worked on the engineering and system integration of its 6-DOF robotic platform.

01

Performance System

The performance combined a 360-degree tornado film, three live violas, and three speakers mounted on the robotic platform.

  • Three live violas
  • Three moving speakers

02

Motion Capture

A lightweight triangular rig with Vicon sensors recorded a dancer's hip movement as motion input for the platform.

Custom Joints

I designed and fabricated custom 3-DOF joints for each actuator endpoint with the Penn Mechanical Engineering Department, using steel stock and stress and fatigue analysis.

  • Basic steel stock
  • Stress and fatigue analysis

Motion Processing

Vicon data was exported to Excel and processed in a custom MATLAB simulation. We adjusted gains and edited the data to preserve expression within the platform's operating range.

  • Excel motion data
  • MATLAB simulation
  • Gain tuning

Live Performance

The audience lay beneath the dome surrounded by robotic motion, live violas, and amplified mechanical sound.
