Self-driving Toycar: Difference between revisions

Revision as of 21:32, 23 February 2017

Soon you will find here a step by step guide towards a self-driving toycar!

Remove the screws on the bottom and remove the top.
Cut of all the wires going to the BCP, as close as possible to the PCB. (make sure the power switch keeps working and that it is off)

Connect the motors to driver/h-bridge.
(Add diagram with pin names. Dependent of which driverboard we're going to use.)
Connect the cars' battery to the driver
Connect (solder) the driver ground to Arduino ground

Test > Sample code to test motors over serial connection.

Ideas:

Add ultrasonic sensor to avoid collisions
The car now always steers either left or right. Can we add straight ahead?
Try to make the steering proportional to the error in the line sensor
Make the light sensor trainable. (Maybe add a button to switch between training / driving mode?)

Connect the line sensor analogue output to A0. GND -> GND VCC -> 5V

-What is exactly we want the participants to learn in this workshop? Do we have learning goals? It is going to involve some electronics/hardware knowledge(voltages/currents, wiring, h-bridge, infrared sensor, ultrasonic), some arduino and some pseudo code maybe.
-I am just curious how deep we want to go into any of these topics...
