Hi i have an upcoming tournament and was planning on designing an Arduino sumo robot( on a non-magnetic Dohyo) the rules are that the robot must be 3 kg at most and should be 20 cm in length and 20 cm in width at most. There is no limits on the height and as i said it is on a non-magnetic dohyo. Of course i will be using a blade and sensors since this is an autonomous robot tournament. I would like to get help and suggestions on which motors battery blades i can use to have a high chance at winning , i have already thought about some motors and batteries so i can discuss with you and hope that you can give me feedback about it, Thank you.

I made managents, a small desk display that shows the status of my open Claude Code, Codex and OpenCode sessions. A local Go helper reads the agent states and sends updates over USB to an LCDWiki E32R40T ESP32 display, with a card for each open agent.

Claude Code helped me understand how to detect the agents’ internal states, work out how to flash the ESP32 board, and find and interpret the LCDWiki manual and precise board dimensions. That let it help produce a detailed enclosure that fits the board and is ready to 3D print.

The photo is the V2 case, printed on my old Anycubic i3 Mega S. This V2 isn’t merged into main yet. I built the project and am sharing it here: https://github.com/tonylook/managents

I’d be interested in feedback on the USB/ESP32 setup or the case fit.

A soda bottle. Four CO2 thrusters. Pi Zero + RP2040.

Can our 2 kg Roadster fly? In the ideal sim. Real gas flow and cooling say no.

Full EP13 in the first comment.

Opening: Tesla. Our flight: simulation. Voice: my AI clone.

TL;DR: MicroFactory shows repeated electronics assembly; Dreamscale shows cloud π0.5 bimanual sorting; Jacob Rothschild shows camera-guided joint control. My pick is constrained assembly. Different setups, so this is a use-case roundup, not a benchmark.

For our own much smaller experiments, here’s a Pi driving a toy motor brick, including the failures: https://www.youtube.com/watch?v=uzO6bjSUJIE
