Passive surface grasping mechanism using directional adhesives
Stanford researchers have designed and successfully tested two prototype dynamic surface grasping devices. These devices use opposed pairs of gecko-inspired directional adhesives to attach to any smooth surface. They require very little energy for attachment and detachment, work on many surfaces, can undergo many attach/release cycles and can be scaled to either small or large applications. Dynamic surface grasping is applicable to landing of micro air vehicles (MAVs) and to grappling objects in space. It can also be used for climbing robots, toys, or any application requiring frequent attachment and detachment from smooth surfaces.
Stage of Research
Applications
- Micro-air vehicles (MAVs) that perch on walls and ceilings
- Space objects grasping such as large panels, fuel tanks, and other orbital debris in space
- Climbing robots, toys, or any application requiring frequent attachment and detachment from surfaces
Advantages
- Low effort and rapid attachment and detachment on any smooth surface
- Can undergo many attach/release cycles
- Can be scaled to either small or large applications
- Does not require suction or a vacuum
- Does not use glue or other sticky adhesives
- The materials do not need to be magnetic
