![]() Note: the two 9v batteries are connected in parallel Arduino gnd - gnd Line Sensor, Bluetooth, and 9v.Arduino 5v pin - vcc Line Sensor and Bluetooth.Seen above is the wiring setup for the breadboard. Note: the line sensors can interfere with each other, so we made a simple cardboard divider for them. Stick the breadboards to the chassis as shown.Īttach the line sensors to the sensor mount and slide them along to space them out approximately evenly. Tap set (some threading is required for this car).Laptop and Arduino IDE (If you have never programmed with an arduino before check out this).Laser Cutter (we used our university's for this, but you can find laser cutters at most hacker/maker spaces.).0.250" thick Spacers (to fit 5-40 screws).Small solderless Breadboards (from amazon) (we used two for expandability, but you can easily reconfigure it for one).Arduino Bluetooth Module (from amazon).two 5V Motors and Wheels (from RadioShack).Ball Caster (from pololu) (I would recommend getting a metal one instead). ![]() 1/8" Acrylic Sheet (this will become the sensor bar).3/8" Acrylic Sheet (this will make up the main chassis).You can't build anything if you don't have any materials! This robot was built using parts sourced from our local RadioShack, pololu, and amazon but you can probably also use found or recycled parts to make yours.
