This purple aluminum frame makes it an excellent robot body. It is a single 2 mm thick bent aluminium piece with a variety of holes, slots and cut-outs for mounting cards, sensors and servos. The sides are designed to fit two'TT' type motors perfectly - you will need four M3 or 4-40 screws about 24mm/1.0" long to mount the motors. At the front, you can screw a ball castor. You can build a very robust (and quite beautiful!) little robot with this metal frame.

    It is made of aluminium, so it is light and strong.
    Anodizing is very attractive.
    Can be used to build a 2 or 4 wheel robot.
    Tons of mounting holes and slots!
    You can drill and cut the aluminum so that it is easy to modify.
    Will not crack or break if it falls down stairs (okay, it happens).

Remember, it's only the metal frame chassis! Motors, wheels, motor driver, microcontroller, etc. are not included!

You will probably also want to use the following to complete the robot body.

    Two TT type direct current geared motors
    Two TT motorized wheels (we have a range!)
    A ball castor

Then you will also need a microcontroller and an engine driver that can drive the 5V DC motors. We recommend one of the following solutions

    Adafruit Motor/Stepper/Servo Shield for Arduino - v2.3
    FeatherWing Motor Driver - FeatherWing Card Add-on
    DC & Stepper Motor HAT for Raspberry PI
    Continuous motor driver - stepper - 1.2A - TB6612 (can drive two DC motors)
    Stepper motor driver - DRV8833 (can drive two DC motors)
   
A microcontroller or an adapted microcomputer is also necessary!
