Programmable robotics toy from SONY uses small minimalist blocks with personality, allowing to be creative with papercraft:

Another video here better presents how you can use a controller and even create your own sumo robots:

From Spoon & Tamago:

Build, play, inspire. That’s the idea behind Sony’s new toy for kids,
designed to inspire a future generation of robotics engineers. Toio
is the result of 5 years of research into developing a toy that’s
simple enough for kids to use, but also sophisticated enough to create a
figurative sandbox where kids can explore the inner-workings of
robotics engineering.

Toio, at first glance, is stunningly simple: the core of the toy is just
2 white cubes with wheels. But don’t be fooled by their appearance. The
tiny cubes pack a whole lot of tech. They respond to motion, are able
to detect the exact location of the other, and can be programmed but
also remote controlled.
