The amazing work of Francisco García was bringing to life one of the old electrical tricycle used for people transportation inside the Expo’92 in Seville, last century.
His work was to design and implement an steering control system. We used new lead batteries (12 + 12V) and added a servomotor with direct coupling to the steering axe.
The controller has been implemented with an Arduno Mega and the PID control has been tuned and programmed in simulink.
For testing purposes, an open loop throttle control system has been added, making it easy to remote drive the vehicle using a PS2 wireless joypad.
It was bot hard and fun.
