Spherical Rolling Robots
Spherical rolling robots move a ball-shaped enclosure through internal actuation. The shell provides the ground contact while internal motion produces rolling.
How these robots work
An internal drive or shifted mass applies motion through the shell. Surface friction and shell size affect travel and turning.
How to compare the task
Compare path tracking on the required surface. Rolling on a smooth floor cannot establish travel through a threshold or loose ground.
Examples and applications
- Rolling education robots
- Enclosed mobile platforms
- Spherical locomotion research
Limits of this category
- Slip changes the relation between command and travel.
- The spherical enclosure limits mounting choices for external tools.
What to check for the intended task
- Measure heading error after repeated turns
- Test shell traction on two surfaces
- Check the largest required threshold
