Play2Perfect learns contact-rich, precise assembly skills like screwing.

The best part is watching the rollouts slowed down: the policy makes tiny corrections and recoveries that are essential for fast, dexterous manipulation.

馃 How can we teach dexterous robots to perform precise, contact-rich assembly?

Introducing Play2Perfect: first learn to play with objects, then perfect the policy for tight insertion, multi-part assembly, and screwing.

Sound on! 馃攰

@tylerlum23 and I have been busy bringing Play2Perfect to new robots and simulators! Here鈥檚 a sneak peek at two robot setups in IsaacLab and MJLab 馃憞

Come chat with us at our poster today at 5pm at #CoRL2026!

Doing manipulation with high inertia robots limits fine dexterity.

@younghyo_park and @BronarsToni have built up a solid line of work analyzing the science of robot learning so we can scale more efficiently! Great work 馃憦

Robot arms can be extremely heavy compared to the objects they are asked to manipulate, especially with their metal links and highly geared motors.

But is that actually a problem for robot learning, or are learning algorithms powerful enough to handle it? Are we paying any hidden costs for using heavy robots? Here's what we found 馃У

Very cool paper! There are a lot of interesting questions to answer when environment interactions are scaled up in GPU-parallelized sims.

Immediately improved the performance of my RL runs after reading their reccommendations :)

1/ As compute continues to grow and simulators continue to improve, it is becoming feasible to train RL agents for billions or trillions of timesteps. However, this is only useful if agents can continue learning over such long training horizons, which is far from given 馃憞
