REK is expanding to Japan! π―π΅
Following the success of our REK Tokyo event, we are opening a permanent arena in Tokyo, led by Hiroki Watanabe, a true samurai @robotsmasher1
Interested in helping out with the expansion? Reach out to @rekjapan!
Unitree Introducing: H2-X Kung Fu Legend Guardianπ€
Powerful performance to serve and guard you, with a maximum endurance of approximately 8 hours.
Please use the robot safely and in a friendly manner.
DAY 1: Humanoid Robot Fashion Challenge
Itβs the first time Iβm seeing fashion designers, robotics people and HRI researchers come together to think about designing for new bodies.
Coding agents can now control 32 different robot embodiments through one API.
BenchFlow has released Robo Use, a common interface that lets AI agents control very different simulated robots through the same set of commands.
The launch covers 32 embodiments, 100+ scenarios, 11 agents and models, with 2,500+ trials already run.
Its current public stack goes even broader, spanning Meta-World, LIBERO, robosuite, RoboCasa, ManiSkill, HumanoidBench, MuJoCo Menagerie and more, with robots ranging from Franka and Sawyer arms to Unitree humanoids, Spot, ANYmal, Apollo, TIAGo, dexterous hands and drones.
Opus 5.5 + Claude Code currently ranks first overall at 306/342 solved tasks, ahead of GPT-6 Astra + Codex at 289/339.
But there is an important wrinkle: according to the launch results, Opus gains part of that lead through refusing harmful physical tasks. Across the 292 shared non-harm tasks, GPT-6 Astra leads 269 to 262.
So "which model is best at robotics?" is becoming a much harder question.
Model capability matters. So do the harness, safety behavior, perception interface, controller, simulator and embodiment.
Robo Use is interesting because it starts putting those variables into one comparable infrastructure.

Announcing REK for iOS (Beta)
We built a 1 to 1 sim that runs the entire physics and robot ai that can be used on a phone. So anyone in the world can train to be a robot pilot!
Ok so this game has eaten most of my weekend. It's all the fault of @Twelvisten and his relentless critique.
"This is cool man!" is nice to hear but when someone tells you everything that is wrong with what you made, you can truly make it great.
We went through a whole bunch of rounds of critique and it helped me add real depth to this little game.
Please give it a go. You'll love it. I have also added leaderboards for easy, medium and hard difficulty levels.
When the game is over, it checks the leaderboard and if you beat one of the top 10 scores you can leave your name.
Game works great on desktop AND mobile. Made with Astra using @threejs for the graphics. All SFX were rendered using the @ElevenLabs API and the vaporwave music was made with @suno.
Have fun!

Artificial muscles are increasingly resembling biological muscles.
This robotic actuator contracts from a length of approximately 120 mm to 108 mm.
When current flows through its electromagnetic system the braided body shortens and thickens thereby generating mechanical movement.
It is also possible to connect multiple artificial muscles in series to achieve a greater range of motion or in parallel to increase force.
This type of flexible actuator is being studied for applications such as humanoid robots robotic arms and hands and soft robotics fields where joints require controlled movement within a compact structure.
What particularly catches my attention is the physical contraction one can actually see the artificial muscle shorten and expand laterally while producing movement.
