Undated, guilt-free, and a toy on purpose. The ground track's perception sandbox.
The Bambu Lab CyberBrick forklift (already built and functional), converted into a tunnel-row plant-photography scout.
petsi (a Raspberry Pi 5) is the brain — ArduCam on a swivel servo, WiFi, telemetry to the ambient display. The CyberBrick Core (ESP32-C3, MicroPython) stays on as the actuator controller: 2 DC motor channels + 4 servo ports, commanded over its USB-C serial port. That's the companion-computer pattern — the same architecture as Pixhawk + ground station, at 1/50th the price.
- Teleop conversion: forklift drives as a scout under keyboard/web control via the Pi
- Serial bridge: Pi ↔ CyberBrick command protocol; camera swivels on command
- Row survey: crawl a tunnel row, photograph every plant, build the dated dataset
Scope, honestly: Toy-tier drivetrain (plastic 1:48 gears, 030 motors, no encoders) — it will never push through mulch, and that's fine. The drivetrain is disposable; the perception stack, serial protocol, and data pipeline all transfer to Year 2's real rover.
