I built this robot for an educational project. You can easily print the parts. For the electronics: Motherboard: I chose Arduino Nano, available at http://www.ebay.com/itm/MINI-USB-Nano-V3-0-ATmega328P-CH340G-5V-16M-Micro-controller-board-Arduino-/162008656870?hash=item25b877ebe6:g:hikAAOSw44BYfJ2F. Electronic Speed Controller: I selected L293D, found at http://www.ebay.com/itm/5Pcs-L293D-L293-Push-Pull-Four-Channel-Motor-Driver-IC-/130753383901?hash=item1e71824ddd:g:~UAAAOSwARZXlwJx. Motors: I opted for mini motors with a gearbox, available at https://hobbyking.com/en_us/brushed-motor-15mm-6v-20000kv-w-298-1-ratio-gearbox.html. Servo: I selected 6gr servo, found at https://hobbyking.com/en_us/turnigytm-tgy-d56lv-coreless-low-voltage-ds-mg-servo-0-89kg-0-10sec-5-6g.html. Sensors: I used Sharp, available at https://hobbyking.com/en_us/kingduino-gp2d12-sharp-infrared-distance-sensor.html. You can also use another Sharp sensor or an HC-SR04 ultrasonic sensor with a different bracket. You will only need two sensors from this list. Accessories: I included a belt, M3 screws, tape, glue, PCB (with soldering skills), wires, a 2S lipo battery, a switch, and a fan (optional). Print Settings: Printer Brand: Prusa Printer: Prusa Steel Infill: 70%
