Scientific Achievement

The excellent strength-to-weight ratio of polypropylene tubing enables construction of exoskeletons inspired by spiders, ants, and water striders.

Significance and Impact

Inspired by nature, arthrobots combine mechanical compliance, lightweight and simple construction, and inexpensive yet scalable design.

Research Details

  • Constructed using polypropylene tubing (drinking straws) and elastomeric tubing.
  • Designed to be nimble, an Arduino microcontroller and valves control gait.
  • Arthrobots are “Cooperative” systems that are well suited for safe robot-human interaction.
