Electroadhesive grippers are a great way for a robot to be able to grip objects and SRI have been developing general-purpose, highly-compliant electroadhesive pads for a variety of applications including wall climbing robots and now robot grippers.
Electroadhesive when used in grippers will allow a robot to grip pretty much any surface, be it conductive, non-conductive, smooth, rough, or even covered in dirt.
An electroadhesive grip doesn’t need complex sensors or programming to do its job. Simply put the gripper in contact with an object, turn on the electroadhesion, and pick it up. Being thin and flexible the surfaces can be used for a number of different applications.
