Creating Pendulum Motion

  1. Jan 5, 2009 #1
    Hi I want to build an upsidedown pendulum. My problem is what is the best/most used way of converting a circular motion (from the motor) to a pendulum motion.

    Look up 'escapement' there have been lots of different ones invented over the years.

    It may be a little easier to build a simple crank-slider assembly, shown here:

    All you then need to do is connect the slider to another joint, which has a fixed pivot point. Then adjust your lengths to get the speed/angle sweep that you desire.

    Thanks the 'simple crank-slider assembly' was exactly what I was thinking of.
