Wire Beings beta is an open source robot for Arduino that can be 3D printed.
This is a nice project that you can continue to work on and modify as you learn more Arduino projects. This Instructable goes through the complete build for the bluetooth enabled robot in the first half of the video.
As long as you have a 3D printer this project is really easy to do and the electronic parts cost only around $30-$35. It takes in total about 35 hours to 3D print, but can be assembled and programmed in around 30 minutes. Requires only 2 screwdrivers to build and does not require any soldering.
Step 1: Gather 3d printed parts, tools, and electronic components.
First gather all the 3d printed parts that can be downloaded from Thingiverse.
Tools: You will need a regular screwdriver, a skinny screwdriver, superglue, and a little sandpaper.
Parts:
$9 ———————2 Wheels with DC Motors
$3 ——————— 4 pieces of thin insulated wire (about 4 inches each) if the DC motors do not already have them.
$3————-l298 Motor Driver
$4———————-Arduino Uno R3 board
$4————————Jumper Wires (male to male and female to male)
$1———————9v Battery Holder
$2———————-HC-Sr04 sensor
$1————————Mini breadboard
$2————————2 RGB LEDS
$1————————3 220 ohm resistors
$3————————HC-06 Bluetooth module
$7————————6-32 X 1/2″ SCREWS (Usually come in a pack of 100, only about 40 are needed)
? ———————— 9 volt battery
