Bipedal walking robots come in all sizes, from tiny robots like the JVC J4 that you can hold in the palm of your hand and Robo-One class robots that can be the size of a small baby, all the up to huge walking robots that tower over 3 meters (10 feet) tall. The contrast was made abundantly clear last November, at the Japan Robot Festival in Toyama.
It turns out that A-Do, one of the Robo-One battle robots that did pretty well in the competitions last year, attended the Toyama robot festival. A-Do is probably around average size for Robo-One - 2.5 kg (5.5 pounds) and 40 cm tall (15.74 inches).
Unlike some of the other Robo-One robots, A-Do has a tremendous amount of personality and crowd appeal. He sports a huge afro hairdo, usually wears a special costume, and some how manages to incorporate unique moves into his bouts. He's always a lot of fun to watch.
And, as luck would have it, the huge Sakakibara "Land Walker" robot also attended the festival. Land Walker is 3.4 meters tall (11.2 feet) and weighs around 1,000 kg. (just over 1 ton). It's powered by a 250 cc engine and can walk at a speed of 1.5 km/hr (0.9 mph). It could easily crush A-Do underfoot by accident and not even notice it.
A-Do fights with his fists and wits. Land Walker has two mounted gun turrets. This could have gotten ugly, especially for A-Do since Robo-One class robots aren't known for being too stable when they run (away). Thankfully, they decided not to fight, and quickly became fast friends.
