Opus 5.5 is unreal. This whole game, this whole video, this whole song All made by Opus 5.5 and I've actually had a bunch of fun playing it I'll link it if anybody wants to play

I one-shotted this with Opus 5.5 It's a simulation of a T-rex 66 Mil years ago Linked in replies...

From barely standing to fully self-balancing — this is my hexapod robot, week 1 vs now. Everything here is custom: the controller, the code, and every single part is 3D printed — no kits, no pre-built parts. I'm 15 and building this entirely from scratch, mostly by trial and error. This is the progress so far. More updates coming as it keeps improving.

15y/o makes 0.22mm repeatable robot arm! This is a robot arm actuator built for a shoulder joint. The design uses a high RPM motor with a 500:1 gear reduction. This achieves high accuracy and strength. The design uses a capstan drive speed reducer. Which uses rope instead of gears, this achieves low to almost no backlash. Built for less than $200, and still prototyping. The base is made of mostly carbon fiber and 3d printing. The trial was conducted over 20 tests and used a dial indicator as the measuring device.

We scored higher than Harvard kids! -Today in class we did the Harvard Mt Everest challenge, and team building exercise. -My team and I scored 96% and Harvard students on average only scored 60%
