This week, after the success of or first prototype, we did some development on how we would integrate a motor into the model.Gif.gif

Though the initial model worked, we noticed a few issues. If we did not provide the same amount of force on either string, then one set of legs would pull in before the other. Another problem we found was that there was no way to return it to it’s original state as strings only work in tension.

In our development we solved this with a reverse linkage mechanism. This would not only apply an equal amount of force in both directions but also allow the model to retract back inwards if the motor input is reversed.
