Before T-Quad, you had one different robot for each application: one 4 wheels robot, one 2 wheels robot, one self-balancing robot,...
With T-Quad, you can do all this with a unique robot.
T-Quad with 4 x Mecanum wheels
T-Quad can be used in different configurations.
On the left, we uses 4 x Mecanum wheels. With these wheels, the robot can not only go forward, backward and turn, it can also translate right or left ! In fact, depending on the combination of rotation speed of the four Mecanum wheels, any kind of motion is possible.
On the right, a Raspberry Pi is added to the robot. You can use it to add high performance communication features (Wifi communication, real-time video streaming) or high level control (obstacle avoidance, object recognition,...) with different languages (Python for example).
You can use almost any kind of mini-computer (not only a Raspberry Pi ; it can be also, for example, a BeagleBone Black, a pcDuino, a C.H.I.P., an Odroid,...) provided that it has an i2c link, whatever the voltage level (3.3V or 5V).

T-Quad with 2 x normal wheels and ballcaster
T-Quad can also be used with standard wheels.
On the left, it works in a classical way with a ballcaster.
On the right, you can see the self-balancing configuration. T-Quad integrates various sensors (see below) in order to perform this kind of advanced control.
We also added a nice feature: the ultrasonic sensor is mounted on an manually adjustable angle bracket. Whatever the orientation of T-Quad (horizontal or vertical), you can use this distance sensor (and also the optional Webcam, mounted on the same bracket) !
T-Quad in self-balancing mode
T-Quad is a robot Shield for Arduino Mega 2560 with a lot of features:
4 x DC Motors 6V with incremental encoders
Current measurement on the 4 motors (or physical parameters identification)
