Lab 2. Manual control of object moving (1 week lab)
A.G.Chefranov, 25.03.2004, Comp. Eng. Dept., EMU, Gazimagusa
In this Lab you are to write a program providing output of graphical image of cart with
inverted pendulum similar to Fig. (don’t not show l,y,u, , sizes, directions, axes)
Lab Task:
Write a program which will
1. Provide graphical output of cart with inverted pendulum on the screen
2. Provide interface allowing user to move cart with pendulum as a whole rightwards and
leftwards (keys Right-Arrow, Left-Arrow, respectively), and rotate pendulum without
move of cart (Up-Arrow, Down-Arrow, respectively; clockwise or counter-clockwise
direction of descending from vertical position should be made by random choice).
3. Each key-stroke should lead to 1-step modification of current state (for example, 1 click
on Left-Arrow button will move cart by 5 pixels leftward – if step is 5 pixels; 1 click on
Up-Arrow button should rise pendulum by angle of 50 – if step is 50)
Defense of Lab:
1. Show and explain program
2. Submit printed report with title, task description(0.5-1 page), description of your
algorithm (1-2 pages), program description (1-2 pages), appendix with sources
3. Time for defense – 1.04.2004, 8.30-10.00, CMPE-238.
