01 / STUDY

Mechanism and experiments

Stanford researchers use tip growth instead of whole-body sliding and explore camera access through obstacles. Technology-development materials discuss the body, walls and underground spaces.

02 / CONTEXT

Test conditions and scope

The work includes motion through obstacles and camera-carrying tests. Use in the body, walls or underground needs application-specific validation.
