THE DRIVETRAIN
A traditional geometry with four-wheel drive, independent suspension, and 80 mm all-terrain tyres.
THE BRUSHED MOTOR + ESC
A purpose-spec brushed motor with integrated encoder. The motor converts electrical energy into mechanical energy to provide power.
The motor is driven by an ESC (electronic speed controller). It reads the control signal and adjusts the power delivered to the motor accordingly, which sets both the speed and the direction the motor turns. This is what gives precise control over the motor's speed and torque. The signal comes from the OSCORE board.

THE STEERING SERVO
The steering servo turns the front wheels. It is much stronger than a car this size needs, so it will not strip its gears if the car hits a wall. It is also waterproof.
