Sandia, in partnership with Stanford, has created a dexterous robot hand for the DARPA’s ARM program. It’s addresses issues that have plagued previously developed arms, such as cost, durability, dexterity and modularity. It’s amazing how you can just snap on the fingers to form the hand and it has a skin that is able to mimic human tissue allowing for a better grip on objects.
Since the hand is modular and fingers can be attached magnetically according to the use of the robot, it would give us the opportunity to expand the use of the hand by looking at different configurations of the hand. Given the way the fingers are attached, it’s possible for the hand to pick up fingers and attach them as well. This gives the robot the flexibility to easily change the configuration of the hand during operation.
The fingers are costed around $800 per degree of freedom for low-volume productions and hence the 12 degrees of freedom hand would cost around $10,000. Sandia claim this to be cheaper than similar industrial hand with identical degrees of freedom.
Have a look at the video to see how dexterous the hand can be.
