Variable Friction Manipulation

Dexterity is often achieved in robotic grippers by increasing the number of degrees of freedom (DOF). We take an alternative approach of modifying the friction of robotic fingertips. 

The original Variable Friction Gripper was developed by Dr Spiers while a member of Yale University's GRAB Lab.

We are developing a new version of the variable friction gripper that is easier and cheaper to build and control. Watch this space!
