Have a robotics project, cool activity, or CTE/STEM idea to share? Post it here and tell the community what you created, what students learned, and which WLKATA products or tools you used.
We’ll also share helpful resources, project ideas, and teaching materials here. Feel free to ask questions, exchange ideas, and learn from other teachers, students, and robotics enthusiasts.
Photos, videos, lesson plans, code, and project files are all welcome.
I have been doing some controller-level work on the onboard ATmega2560 over USB. That is a step below Studio and G-code: custom firmware talking directly to the steppers and gripper.
It includes an empirical pin map for all four joints (STEP, DIR, ENABLE), Cartesian keyboard/gamepad jog with on-device homing, scripts to back up and restore stock firmware so you can experiment safely, overhead-camera vision for colored-cube pick-and-place, and an MCP server so an agent can drive the arm. There are also archived notes from looking at the stock firmware if you are curious how the controller is built.
Feedback welcome, especially if your unit behaves differently.
This is awesome—thanks for sharing your work with the community!
Really appreciate all the time you put into documenting everything and making it open source. I’m sure the pin mapping, firmware backup/restore tools, and controller notes will be a huge help for other MT4 users who like to tinker.
