Modular robotics for adaptive and self-organizing furniture that moves, self-assembles, and self-reconfigures. Our dream is to provide multi-functional modules that are merged with the furniture and that lay users and engineers can combine for multiple applications.

Key features:
  • Off-grid (free) and on-grid locomotion
  • Position, speed or Central-Pattern-Generator (CPG) control
  • One module can lift another module and up to 500 g as payload in the end effector
  • Extensible with specialized elements (Universal Gripper, LED spotlight, camera + on-board PC)
  • 2 LED rings per module for visual feedback
  • Local sensors to detect docking position
  • 10 connection surfaces per module
  • 3 degrees of freedom and 2 active connection mechanisms per module
  • Controlled from centralized PC; commands over serial port on Bluetooth
  • Easy-to-use GUI (based on Unity; only visualization, no physics)
Possible applications:
  • Novel interface to control and coordinate multiple modules at the same time
  • Smart moving manipulator or spotlight
  • Automatic construction of shapes or objects
  • Rapid prototyping of robots by coordinating multiple modules
