Catching a flying ball is hard. What if with a flat plate? 🏓 Our work at RSS’26 shows it’s possible through Zero-Shot Sim2Real With Domain-Randomized Instance Set (DRIS), we catches different kinds of balls without any real-world fine-tuning 🔗 rice-robotpi-lab.github.io/DRIScatch/

XLeRobot trained with SmolVLA, shot in real-time. This makes me really looking forward to the hackathon on Oct 24-25. Made by Makermods QiLiu.

XLeRobot Sim2real RL: Only 1hr RL training in pure simulation (Maniskill) with a 4090 GPU and then we got this. Faster and smoother than most of the VLA models I have seen on LeRobot. Codes and tutorials fully open-sourced: github.com/StoneT2000/ler… Many thanks to @Stone_Tao!

XLeRobot 0.2.0 Trailer 2: (still controlled by keyboard) Just realized, don’t even need to numerically calculate a complicated IK for SO100 arms. Just use Law of Cosines and analytically get everything. Also only one solution for every EE pose so it theoretically couldn’t have

Anyone in the LeRobot Hackathons are trying this? github.com/Vector-Wangel/… Finally make it fully assembled with a nice cable management. Left a HDMI tail on the back to connect to the monitor.

XLeRobot 0.2.0 Trailer: Some simple keyboard joint controls in Maniskill. Pick a bottle, open the fridge, place the bottle, close the fridge. Done in one run, just clipped it to save some time. Not perfect, but real enough.
