Notes

A direct-drive quadruped developed by Ghost Robotics and University of Pennsylvania researchers.

High-torque direct-drive brushless motors on 5-bar linkage legs, without gearboxes, give direct force transparency and a fast, dynamic response.

The manufacturer's own pages do not name its city; U.S. federal contract records (USAspending.gov) give Ghost Robotics Corporation's address in Philadelphia, Pennsylvania.
