Months back, I posted up about the Kinetic Sculptures by Theo Jansen... which were basically robots, made from simplistic material, and powered by nature...
Well, the original sculpture is something like this. And can be powered by the wind..
Now, a robotics expert, has made one for his son.
"I made this just for my son (2 years old), because he told me "Dad! I wand to ride on a robot". This is just a toy for my son."
LCX was designed to allow 360kg static weight and able to locomote with 90kg(tested). It is controlled by both wired remote controller and center of weight sensor. It's power sorce is 7.2V Ni-H battery that is used to RC and locomote 45min with human ride...
All I can say is, dang, what a cool dad and a lucky son =3
