Check parts
Before we start, we have to check if we have all parts need for the upcoming
workshops.
The computer is the robot’s brain. This is where all information of
the sensors come in. After that the computer decides what to do
with these measurements. It sends a signal to the microcontroller
to control the actuators. The computer also creates the connection
to your own laptop.
The microcontroller receives the measurements of the sensors
and sends these to the computer. The microcontroller also
receives the instructions from the computer to control the
actuators (like motors).
The motor driver makes sure that the motors will get the right
voltage, in order for the motor to turn with the desired speed
and direction. Without this driver, the motor would only be able
to be on or off.
The Mirte PCB is used to easily connect all components. In this way
you connect the computer, microcontroller, motor driver and all
sensors and actuators.
The robot of course also needs power. This is usually an electrical
battery. The battery makes sure that all electrical components can work.
The motor ensures that the wheels can turn around and your robot is
able to drive.
The wheels makes sure your robot is able to drive.
The ball caster makes sure your robot is stable and does not tip
over. If your robot would only have 2 wheels, it would have to
balance itself (which is quite hard).
The linefollow sensor can measure the lightness of an object it is
looking at. When faced towards the floor, this sensor can measure
is it is looking at a (dark) line, or a (more light) background.
We need these cables to connect the sensors to the Mirte PCB.
The USB cable is needed to connect the Mirte PCB to the powerbank.
We need the frame to make sure all components stay together.
