Up-down motor module. Rack and pinion, one servo motor, one touch sensor.Forward-backward motor module. Two linear actuators, one servo motor, one touch sensor.Left-right motor module. Rack and pinion, one servo motor, one touch sensor.EV3 computer brick. I wrote the program in MicroPython on a laptop, then loaded the program into the brick. Because each motor module has a similar pattern, (linear motion, one servo motor, one touch sensor) I programmed all three motor modules as one class.
Next Steps
Maybe I’ll fix some design defects. Or maybe I’ll just take this all apart, sort the parts into my airline service trolley, then think up a new challenge. Play is good.
