X-Y Joystick Remote-Controlled Device

This second model is more complex:
  • a first X-Y accelerometer is installed on top of the joystick,
  • a second accelerometer on a X-Y device is moved by two motors,
  • the goal is to replicate the angle from the joystick to the device.  

Hardware

The device consists of two axis, each one with one motor and two end-of-course safety switches. 

The yellow lamp shows activity.

Below, 
  • The joystick includes the accelerometer and a trigger on top.
  • Detail of one axis with its motor.
  • The end-course contacts for safety.

Software

The software is based on the comparison between the values of the two accelerometers and commands the two motors.

It is pretty basic and relies on fuzzy logic with simple rules.

However, two TX-Cs are needed: each accelerometer requires 3 A/D inputs, and the device needs 4 end-of-course contacts for safety.
