Sam Martin's "CD
of my project is to organize CD's. The user enters the CD names
into the computer, and the computer will alphabetize the CD's and then
my project will move the physical CD's into the correct order.
There are two degrees of freedom (motion) in my project. One axis
moves the mechanism forward and back, which is controlled by a stepper
motor, a pulley system, and a gantry. Mounted on the gantry is a
printer mechanism which controls the second axis, up and down.
The end effector of my project is a lift, using a fairly large angle
bracket mounted to the printer mechanism. The aluminum bars are
mounted onto the angle bracket, giving the effector a fork lift
appearance. On the ends of the bars are pads of rubber (from old
ping pong paddles) that allow the lift to keep the CD's from
shifting. The motors are wired to the interface, which converts
computer signals to pulses that move the motors.
