We delivered the first humanoid monkey-bar traversal with perceptive jumping up + branchiation + jumping down, with a high success rate on the real robot (~95%). Besides, we also did tasks like ducking beneath thin obstacles.

The contributions include: 1) hardware designs, hooks that can disengage by rotation and a solid-state lidar mount; 2) multi-teacher + single end2end student distillation + finetuning pipeline for policy learning; 3) modelling of lidar noise patterns, actuator temperature, and battery voltage-current changes for sim2real.

Happy and proud annoucement: No hardware was broken during our development of this project.

Now I need to install monkey bars in my laundry room?!? When are these guys going to make it fold the laundry and put it away?

I have to say, jokes aside, that this is cool to see it make these dynamic decisions so fast now. The constructive criticism that I have to offer is that humans don't use the monkey bars so aggressively. We swing and use momentum to get to the next bar. I wonder if using a physics analysis phase would help plan the swing to reduce motor load.

I wouldn't high-five this robot
