I used three sensors: light sensor, touch sensor and sound sensor.



The light sensor (Port 3) is located on the claw and lets the robot know, if the ball is there or not (and can recognize the "color" of the ball). The other two sensors are located on the platform of the "tilt module". Touch sensor (Port 1) serves as a sort of a button for me to press while the sound sensor (Port 2) measures the noise level (so I can give the robot commands with a clap for example).



At first, I wanted to include the US sensor as well, but I realized that it's relatively useless. You can still see it on one of the photos, but I removed it afterwards.



Now all that is left to do is the wiring. You must make sure that the wires do not disturb the movement and function in any way. You must also consider wire lengths for each sensor or motor.



Wiring (my robot):

- touch sensor -> Port 1

- sound sensor -> Port 2

- light sensor -> Port 3

- "rotation" motor -> Port A

- "tilt" motor -> Port B

- the claw -> Port C
