Arduino Rover Workshop (Basic)

Topic: Make a basic arduino rover in 1-3 sessions


  • Basically, to create a 3 wheel rover that does the sort of autonomous moving around things that a basic lego NXT robot does but using a basic arduino for brain & really easy to get pastic waste or other waste for chassis etc.
  • Parts
    • something like a 1/1.5 kg honey pot for the chasis?
    • sensors for distance or sound or line following for movement guidance?
    • arduino?
    • electricity- 9v square batteries or battery pack with aa size rechargable batteries-may need double set since servos eat battery more than normal arduino?
    • two servos for wheels with axle
    • not sure if a gearbox/suspension would be needed? (probably not for simple one)
    • either buy driving wheels (I'm sure they are cheap) or improvise, eg: bottle lids with rubber band around for “tread”
    • pivot wheel/wheels set for the third “corner”
    • laptop with arduino software on it for editing and downloading software to the rover
    • USB jack
    • LED on arduino/separately on the rover to indicate that certain stages in a program have been reached (for problem shooting)?
  • control schema:
    • I imagine that the rover would work by telling the wheels to eg “turn for a certain amount of time or doign revolution counting- turn both wheels at the same speed until the distance sensor (ultrasonic??) says something is 10 cm away”
  • goal of workshop:
    • have a working rover and then have them negotiate an obstacle course or scavenger hunt (autonomously), goal could be just finishing or have fastest time or
    • have a rover dance competition.
    • alternatively could pursue a “bomb disposal” theme…..making something to do something that looks like bomb disposal.
    • if you wated to, you could highlight some of the classical robotics problems: callibration of servos, callibration of sensors, programming, interference from outside affecting sensors etc.
  • Extension
    • if we could add a camera to the robot, could then play with streaming wireless video feed back to our laptop?

Duration: I have no idea. I'm guessing this may take a few sessions in a row.

Cost: Could we assume most people have arduino boards already? Some supply of sensors (but assume some people have them already). Main cost should be servos/wheels.
