Looking for an easy way to control that Arduino powered robot you built? We just caught wind of a pair of apps for Android that look pretty handy! WiFi Bot Control and Bluetooth Bot Control.

This machine can be driven directly over Bluetooth ... an Arduino Uno drives two servos and one motor. The 1:90 geared motor drives the robot around using a 180° servo to steer.

The robot arm is controlled using a touchscreen application loaded onto an old smartphone hose inside a control box ... that rotate a particular servo motor to the desired degree.
