With @OpenAI's Realtime API, two ToddlerBots can communicate, allowing one to demonstrate push-ups to the other. This showcases language capabilities and zero-shot sim-to-real transfer with open-loop keyframe animation.

Our design ensures balanced power distribution between ToddlerBot’s upper and lower body. As a result, Toddy has strong arms and pull-ups become effortless as well.

ToddlerBot can grasp objects 14× its torso volume and lift 40% of its weight. It runs RL walking for 19 min before motor heat increases falls. It takes up to 7 falls to break ToddlerBot, with repairs taking just 35 minutes, including 3D printing, assembly, and recalibration.

A huge thanks to my incredible collaborator, @KenWangWeizhuo—this wouldn’t be possible without his hardware expertise. Grateful to my amazing advisors, @SongShuran and C. Karen Liu, for their invaluable guidance and unwavering support.

This is incredible! I'll have to build one of these to go along with @lethic1's RX1

very cool project! is the shuffling gait a result of hardware choices/design or a software limitation, in your opinion?

it's an interplay of both. Dynamixel motors are not that strong, and we are also working hard to improve our algorithm
