PyEilik
Your Eilik, on your terms.
A sealed desk robot, opened up and made programmable — servos, screen and video, over a protocol recovered byte by byte and verified against real hardware.

What was recovered
Section titled “What was recovered”The robot ships sealed, with an app and no documented interface. Everything here came from watching the wire and checking each guess against the hardware.
- The frame format — header, length, command, checksum — and the commands the firmware answers, including the four that are dangerous.
- Four servos, their real travel limits, and how fast they actually move.
- The 128×64 display, both directions: read what is on it, write your own.
- The acknowledgement rule that separates working from dropping the device off the USB bus mid-frame.
What is not possible is written down too: there is no command to play audio through the robot’s speaker — not in this protocol, and not in the manufacturer’s own software either.
