Beam Shooter

What this episode covers

A simple robot that shoots beams and other things that are the same thickness like pencils and bushings. Hardware There are 2 main motors geared up 32 times it's speed - which makes up o 4000 RPM output. shooting the beams very fast and pretty far. At the back there is a gear box (from and OLD BIONICLE set I think) and that adjusts the angle of the shooter up and down. The controller is one motor on the side for controlling the speed and a light sensor for indication the speed range (0-11 is red 12-75 is blue and 75-100 is green) and information is displayed on the screen - read the next section for more info on that. Program The program does a simple task of turning 2 motors but displays a lot on the screen. First it resets the motor on the controller and then the program is started. You use the motor to control the power - every degree = 1% of power. This program calculates the RPM and displays it in a bar and the number. it also displays the % power and the Output RPM. The RPM calculation is from NXT Programs: 3-Speed Transmission with Clutch. You can download the program at my blog.
