Self-Winding and Releasing System for Jumping Robot


Stanford Reference:

13-442


Abstract


Researchers in Prof. Mark Cutkosky’s laboratory have engineered a simple, lightweight, autonomous one-way clutch device designed to power a repeated wind and release mechanism. This technology relies on passive magnetic fields to create two states – locked (at low velocities) and free-spinning (at high velocities). During operation, slow speeds engage the clutch to wind and load a spring to a set deflection. At this point, the magnets act to disengage and release the clutch which rapidly unwinds the spring. This technology could be used for robotics or any application that requires repeated wind and release.

This clutch mechanism was developed to help propel a jumpgliding robot designed to travel over cluttered terrain with greater range than a ballistic jumper. The video below shows a demonstration of the robot including the winding system.


Design principles for efficient, repeated jumpgliding


Applications


  • Autonomous robotics - winding a spring and release mechanism for jumping
  • Mechanical control - any application that requires repeated wind and release

Advantages


  • Autonomous action - no active control or electronics required to perform continuous wind and release
  • Lightweight and compact:
    • single motor
    • current motor and clutch for jumpgliding robotic application is 12g, but could be scaled for larger applications
