Our wonderful little horsebot works. We decided to go with the teflon rods because when we were manually turning the axel, the teflon rod one was easier to turn for some reason. We then proceeded to make our motor.
We need a motor that has one axle so that both of the legs turn at the same rate. This is because our design banks on the fact that the legs on one side opens while the legs on the other side closes. This creates the "horse-like" walking of the robot. However, we do not yet have one axle so the legs do not move at the same rate and so our hosebot falls over sometimes.
We placed the motor on the backside of the horsebot to give him better balance. However, when we also placed the batteries back there, it fell backwards. So we put the motor in the back end and the batteries in the front end this way the back end is still heavier than the front end but not so much so that it falls backwards.
and here it is....
As you can see in the video we were experimenting with putting feet on him. We discovered that putting feet on his back legs helped to balance everything out. So no we have to recreate back legs that have feet on them as well as get a single axel for the motor.
As you may also see from the video, horsebot is basically taped together at this point and time. This is so that we could fix the motor and other parts if we realized that there were problems. We were originally planning on heat staking the robot together. However, if we did that we wouldn't be able to get to the motor. Having made a rough version of the horsebot we realize that it would not be a good idea to heat stake everything together because that would mean it would be extremely hard to make any iterations or fix any motor parts if they came loose. We decided to make the sides and the base a "tight fit" together so that it would hopefully not come apart.
