A unique three-legged robot called "STriDER" is under development at Virginia Tech University. It's name stands for (Self-excited Tripedal Dynamic Experimental Robot. This cunning four-foot tall stick-figure bot has a totally unique way of walking. One researcher described it as being like "a biped with a walking stick."
The STriDER robot is able to change direction by selecting which of its legs to swing through. Two of its legs stand still, and the small body swings underneath and plants the third leg. The robot repeats the process to move forward, swinging this way and that (see video).
