Sakakibara -Kikai well-known industrial robot manufacturer tech enthusiasts , as it was the company that unveiled the world's first bipedal tank prototype in 2006, called Landwalker. This colossus stood 3.40 meters tall, weighed a ton, and had a very similar appearance to the AT-ST or ED-209, but was nowhere near as mobile. I'd even add that calling the mecha bipedal is a stretch, since it can't lift its feet off the ground, only gliding on wheels, although it does have articulations like normal legs. Obviously, the intention wasn't to give it real utility, but only for entertainment purposes, and I'd say the Landwalker fulfills that function well. If you're interested, the robot costs $300,000. The company decided to develop versions for children. In 2010, they demonstrated the Kid's Walker, a smaller-scale variation aimed at entertaining children (or training them, after all, it's Japan, you never know). And now they're back with an improved model, the Kid's Walker NT , which has an important difference: a giant drill on the left arm! Of course, it's just a toy, although it can still cause some accidents, as there's always the "human factor" involved. Like its predecessor, the rider can slightly move their arms and activate the right claw and the left drill, without exaggerated movements. It's the kind of thing that children (and adults) would do anything to have at home and scare the neighbors. And considering that the previous version cost US$20,000, it's best to save up some money before thinking about giving it as a gift to your child.
