Building and Fabricating an Articulated Robot Hand | ETH Zurich Real World Robotics Tutorial 1

Unit 2: Design I
Tutorial 1 of the Real World Robotics Class 2023 at ETH Zürich.
In this video, we explain the core elements of an articulated robot hand. Moreover, an overview of possible joints and different types of actuation is presented.

just make a perfect replica of a human hand, anatomically correct, and use different materials to make analogs for the tissue "tendons bones etc" trust me, nature already solved the mechanical form of the hand.

lmfaooo ok if its so easy why dont you do it?

I wish this awesome technology could be used on upper limb prosthetics, as they are not really helpful and advanced now.

[@christopherd.winnan8701]

What would be the overall decrease in dexterity if you were to combine the two smaller fingers into a single digit? Would one less finger represent a 20% decrease in complexity, weight and printing requirements?
Might I also suggest an addition to your Joint Type diagram at 8.08. As well as flexure, what about compliant mechanism designed using computational origami.

Any chance of a close up of the gearing that you are using to get all those DOF?

[@deepakpandey3133]

great .. keep motivating us

[@bluesquid2291]

the rubiks cube logo thing at the start is actually the wrong colour scheme

[@苏广胜]

Is the pressure feedback system only on the last joint? Could flexible pressure sensors be distributed throughout the palm?

[@christopherd.winnan8701]

They could but they would probably limit strength. Sailmakers use a special reinforced palm which gives them enormous power to sew heavy materials, but at the sacrifice of sensation.

Beutiful viedo

Vielen Dank!

This is SO COOL!!!! I'm a student rn trying to study this stuff because i want to go into the field of bio-mechanical engineering and help with stuff like this!!!!!!! I've found your video to be very helpful tysm!
