Dear SSL-Community,

as in the past years we are very happy to announce our entry for the Open Source Award. The usual one-stop shop to get it all was updated: https://github.com/TIGERs-Mannheim We are doing a complete and full release of everything we have, including electronics, mechanics, firmware, our full AI, and some awesome new tools. Here is a brief description of what has changed.

Mechanics: The dribbler dampening and dribbling bar have changed again to improve traction on the ball. These are mostly material changes. The axes of the sub-wheels changed to be more robust. The release includes the full robot mechanics. Inventor CAD files, but also a STEP file of the full robot.

Firmware: Dribbler current control has been improved near zero velocity. Interface to the robot's raspberry pi has been improved with new messages and feedback of detected balls. The release also includes our wireless protocol and base station firmware.

Software (AI): The heart and brain of our team, the central control software "Sumatra". Of course, compatible with the simulation protocol. So you can test your AI against ours locally. Pass finding has been largely improved and now contains a dynamic learning component. Also watch out for some more serious dribbling moves which will make you sweat 😉

RobotPi: The software for ball detection running on a Raspberry Pi 3A+ on each of our robots. Most of the color blob detection and thresholding has been rewritten and is parallelized via multi-threading. The RPi uses only around 50% of its CPU now.

TIGERs CLAV (Cut Lengthy Audio/Video): This is an C++ ImGui based application able to cut video files based on an SSL gamelog. You can synchronize multiple videos and gamelogs with individual markers and the tool can then cut out non-running stages. This tool is still quite new and may not support every video format, but nonetheless it is already a great help to preprocess videos from matches. Oh and it can create a status overlay video for your videos, too (similar to the status board).

In case you are missing any information or if you are just curios, contact us on Discord or write us an email.

Tigertastic Greetings, TIGERs Mannheim
