EggTorte is the creation of engineer Kato-san, who wanted to create an even smaller mouse-sized micromouse, a maze-running mechanical mouse.

Take a look in this video to see how the robot learns the maze, and then puts the speed on.
(EggTorte mini micromouse)
I really like the speed of this little learning robot; it reminds me of the golden shuttles from the 1941 short story The Mechanical Mice.
...there came a very tiny, very subtle and extremely high-pitched whine. Something small, metallic, glittering had shot through one of the rat holes, fled across the floor toward the churning monstrosity. A trapdoor opened and swallowed it with such swiftness that it had disappeared before I realized what I'd seen...
SF readers may also recall other similar versions of this idea: Ray Bradbury's robot mice from The Martian Chronicles (1950) and dustmice, tiny robot detectives from Greg Bear's Queen of Angels (1990).

Illustrating Classic Heinlein With AI
'Stasis, cold sleep, hibernation, hypothermia, reduced metabolism, call it what you will - the logistics-medicine research teams had found a way to stack people like cordwood and use them when needed.'
Deflector Plasma Screen For Drones ala Star Wars
'If the enemy persists in attacking or even intensifies their power, the density of the plasma in space will suddenly increase, causing it to reflect most of the incoming energy like a mirror.'
