What it can do

Written by Robotheca from the project's documents.

  • Moves an end-effector in 2D space by synchronously winding and unwinding cables
  • Controlled via OSC messages from third-party software like Processing, Grasshopper, TouchOSC, Blender, TouchDesigner, or Unity
  • Supports velocity and position control modes
  • Automatic startup, homing, and shutdown for standalone art installations
  • Can coordinate multiple robots simultaneously
