Workspace setup with the SO-101 robot arm, custom gripper, and peg/keyhole on the table

Training a robot to thread a peg through a keyhole in 36 hours

The setup RoboHack2026 is the first iteration of a robotics-based hackathon organized by AI Team (https://epflaiteam.ch/). You get one robot and 36 hours, as well as tons of tools to impress a jury. We were given a LeRobot SO-101 that we had to assemble first. The last time I built my own hardware was in high school, so I was glad my teammates were able to offset my weaknesses here. Getting it up and running after 4 hours was such a relief, and playing around with teleoperation is a lot of fun! ...

MuJoCo robot arm executing an LLM-generated trajectory on a tabletop scene

What happens when you let an LLM write robot programs?

In 2022 I was tasked with designing an interactive robot system that takes a natural language instruction and outputs a working robot trajectory. This is a write-up of the design decisions and a showcase of a web demo using MuJoCo that. The code in this demo is a rebuild of the original code "Prompt: Put all the cubes on the plate" How can you make robots listen to what a user says? Human-Robot-Interaction (HRI) has come a long way over the last couple of years. Vision-Language-Action Models are the de facto state of the art in robotics research. PhAIL is a leaderboard aimed at measuring real-world performance against humans, which makes it clear that general physical AI is not there yet. ...
