Inverted Pendulum

Akshay Kumar | July 21st, 2008

hi,
Iam a roboticists and I like to build robots. Many of you would have heard about the famous problem in control systems called the Inverted Pendulum. I have currently turned my attention towards it and have started doing research on it. within a week or so i am going to start the project.

Basically, it is a benchmark for testing many control theory algorithms including fuzzy and neural networks. it is a system where a stick or a pole will be balanced in the inverted position, automatically. i think everyone would have balanced a stick on one’s finger, my machine would just do that…

    How about using micro sized pressure plates that measure weight variances.
    using a complex algorithem, you might be able to detect the differences in pressure from a to b thus resulting in the robot to maintain nano second corrections in the direction of the pressure differences.
    Of course you would have to have a starting point (Balance in all directions should equal ….) so the machine would instantly correct for the differences in pressure according to which direction stick moves.
    Example: 1.5 pounds starting point in all directions.
    as stick moves right.
    1.5 pounds to right. 1 pound to left. Correct .5 pounds to left.
    All this would have to be instantaneous of course and the movements smooth and controlled.
    Just an idea.

    I’ve seen this done using a rotary encoder at the balancing point to determine position, and PID software. It’s somewhere on http://www.microchip.com
