The excellent strength-to-weight ratio of polypropylene tubing enables construction of exoskeletons inspired by spiders, ants, and water striders.
A six-legged arthrobot on water
Significance and Impact
Inspired by nature, arthrobots combine mechanical compliance, lightweight and simple construction, and inexpensive yet scalable design.
- 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.
