Motors

Chain Wheel

Chain Wheels

These are the chain wheels. Each of them is connected to a large motor to move the roboter around.

Grabber

This is the snapper. It has a medium motor to open and close the shovels.

Sensors

Bumper

This is one of the two bumpers. It uses a touch sensor to stop the roboter if it crashed into an object which is not movable.

Windows Phone App

Controller

Here you see the UI of the Windows Phone app. Use the joystick to move the robot. With the two buttons beneath the joystick you can turn the robot left or right on the spot. The two buttons on the right are to open and close the snapper.

We use the legoev3.codeplex.com library for the actual connection. Note that you need to pair your phone to the robot before you can start using the app.
