You will only be using one color sensor for the basic Driodbot build. I will add color sensors as you need them.
Droidbot Modification #1
The two red and grey pieces pictured below will need to be removed, since they interfere with the ultrasonic sensor.Â
You will need to modify the Droidbot using the two pieces you see below. Just use the pictures as a guide to place the new pieces on the robot.
The final modified Droidbot will look like the picture below:
Droidbot Modification #2
You will also need to make these cable holders
This is how it attaches to your robot
Droidbot Modification #3
The front white beam shown below interferes with the ultrasonic sensor and will need to be removed.
Build the pieces below for the modification.
Finished modification.
