    $6,500 for OpenArm v2. Incredibly smooth movement, 4kg of load per arm. Its unclear how far the level of autonomous control has come so far. The video shows mostly tele-operated operation. I have to agree with other comments here that folding laundry is the killer app.

      One would expect it to at least have calibration and inverse kinematics solved. That's still a massive pain point for the SO-ARM101 despite it being so common now, since there's no base_link to gripper calibration nor sag compensation and every center offset stacks.

      Lerobot banked on having full DL control of each joint so they wouldn't have to do that properly, but now VLAs just use inverse kinematics as a crutch and predict gripper offsets, so we're back to square one.

      Crosses fingers for a general purpose laundry folding bot

        We've come a long way from watching 50x speedups [1] to real-time [2] videos of watching robots fold clothes, student-style.

          To me it does not seem like progress that, on a stressed and finite planet, humanity might "need" an energy- and resource-intensive machine to complete a task as physically undemanding (and even frivolous) as folding a sheet. But here we are.

            I just want my laundry folding robot to run slower than me, and not be able to do karate backflips etc in the event of some undesired scope creep happening one day.

              I've got a collection of socks needing darning!

                One step closer to becoming Adam Jensen

                  Or Smasher, there's a few Adams we're taking steps towards

                      A fully open-source humanoid arm for physical 
                      AI research and deployment in contact-rich 
                      environments.
                    
                    When will someone release this but for deployment in target-rich environments?

                      I think in target-rich environments, the humanoid form is pretty easy to beat.
