Ro-Bot-X Designs brings you kits for an easy way to build robots with Arduino.
Get the Robot Builder's Shield kit if you already have an Arduino and want a shield that allows you to control 2 small DC motors, 6 servos, 6 sensors. Use the prototyping area to customize the shield to your liking!
Get the µBotino controller kit if you want to build a tiny robot and you don't need the shield support. A board of only 2" square (5cm square) has packed an Arduino compatible microcontroller, H-bridge, connectors for 5 servos and 6 sensors plus a few extra pins and features. This is the best board for an Arduino version of the Start Here robot! All you need extra is a USB-serial cable.
Get the Robot Builder's R-duino kit if you want to build a robot and you don't already have an Arduino. At only $30 you get both the Arduino and the Robot Builder's Shield functionality (minus the prototyping area). You also get more powerful voltage regulators than original Arduino and built in power switches. All you need extra is a USB-serial cable.
Don't forget to get the cheap USB-serial cable instead of the expensive FTDI cables or breakout boards!
Cheers and Happy roboteering!
