- My RC10B4
This was assembled from a kit and has an electronic speed controller linked to a brushless motor, servo for steering, an old racing battery and a receiver (unused for this autonomous experiment).
The Arduino Uno is a great little microprocessor board that allows you to run c programs to do things. It has 13 digital inputs/outputs and 6 analog inputs. Of the digital outputs 6 of them support pulse width modulation (PWM), which means they can drive servos or electronic speed controllers. The Arduino has a great website with lots of resources. I can already program in c, so I found it very easy to pick up and use. The .:oomlout:. website has a great starter kit (It's where I get my stuff for now, but not the only webstore out there).
This comes as a kit that needs to be soldered together.
My one has removable power strips to make it more compact.
- An extra servo (already had this lying around)
- Sharp GP2Y0A21YK infra red distance sensor.
This can give distance reading between 10 and 80cm.
- Lots of blu tack
- Ice cream box lid
This is how to build my prototype,
- Cut the lid to 66x84mm and drilled 6 3mm holes. Two holes are 53mm apart on the short edge as shown above and the other holes match the arduino (use a pen through the holes in the arduino to find where to drill them).
- Attach the arduino to the ice cream box lid using plastic screws and nuts. The locations of the screws are important, also make sure you attach a nut between the arduino and the lid to keep it off the lid.
5. Unscrew these screws (9643 from step 5 on page 9 of the car manual).
6. Screw the lid onto the car using the screw that where just removed. Make sure you have a charged battery already in the car, otherwise you have to take it all apart to get a battery in or out.
So that is what I built as my prototype. Next post will be the videos of it working and the program uploaded to the arduino.
