The description below is from DRV47 from our forums. Thanks for the post!

This is our first project using the NXTcam v3

The aim of this bot is to find and shoot down three red targets. It’s programmed with RobotC.

The design is the Multi-Bot by Dave Parker from (except for the NXTcam module and the LEGO Color Sensor).

Here are some pictures of the robot:








The robot searches and detects red targets made out of LEGOs, it then moves into position as follows:

– It aims at the center of the target

– It moves forward or backward until the height of the target is right.

If the robot hits anything with the two bumpers, it will move out of the way. The robot will turn on a different LED on the Color Sensor depending on the situation:

-Green while searching.

-Blue while aiming.

-Red while firing (blinking at first).
