Why Robotics Still Isn't Solved - But Could Be Soon | YC Paper Club

Video summary

YC Robotics Club researchers tackle robot memory, action reasoning, and dexterous tool use as startups seek practical deployment.

At YC Robotics Club, the host argues that robotics has repeatedly been declared “solved next year,” yet teleoperation remains difficult and robots still face the sim-to-real gap, weak action representations, limited touch sensing, and embodiment drift. Marcel Torne presents MEM, which compresses short visual context and longer textual memory so robots can track progress, avoid burning food, and adapt after mistakes. Milan Ganai’s self-supervised method selects concise, action-predictive reasoning, improving policies across manipulation, navigation, and driving. Tyler Lum demonstrates Sim2Real: one simulation-trained policy controls a 22-DOF hand and 7-DOF arm at 60 Hz, handling 12 unseen tool-and-task combinations; Play to Perfect extends this approach to precise assembly. Rerun co-founder Nico urges startups to solve customer problems with teleoperation and off-the-shelf hardware first. General Instinct closes with ways to accelerate world-action models, reducing flow-matching inference from as many as 50–100 steps to one or two.
