LEGO ROBOT ANT by RICHARD TAYLOR

This is what your Lego ant robot should look like. It does not look a lot like a real ant, but it is a hexapod, so it does have six legs just like an insect.
According to Richard, this ant design needs quite a lot of power to lift itself up and down as it walks. He suggests that you use fresh batteries in your motor's power box. Reversing the direction that the motor spins, using the switch on the power box, will make the ant walk forwards and backwards - but not turn corners. To be able to do that this robot would need two motors and two sets of gears, one for each side of the ant.
Helical (6) cut gears are not that efficient. Also, the sliders create a lot of drag where the ratio of turn (9) to leg-stroke length is not conducive to an effective walking gait. Lubrication would ease the leg (push-rod) movement, but would also make a mess as any fluids dribbled down the legs onto a table.
The object of this exercise is to get young engineers to experiment to use motors in different ways to achieve locomotion. By amalgamating motors with static Lego parts, budding students can bring their creations to life.
