Remote-controlled gadgets are nothing new, but remote-controlled humans and cars just might be. Continue reading to see three interesting R/C gadgets.

Remote-Controlled Humans

That’s right, Japanese researchers have developed a device that stimulates “the vestibular system with a small jolt of electricity delivered just behind the ear from a small external device, sending the normal vestibular signals out of whack.”

But the device doesn’t work as well as a remote-controlled car. A quick jolt to one side of the head makes people feel like they’re falling over, so they correct their balance by moving to one side or the other, creating a swaying type of walk

Remote-Controlled Cars

Richard Hammond and James May have some fun with full sized remote-controlled cars in this entertaining Top Gear segment.

Remote-Controlled Koi

Japanese researchers at Ryomei Engineering have developed a line of robotic carp — “modeled after a Nishiki koi carp as a form of tribute to Hiroshima Castle ” — that come equipped with CCD cameras and sensors for analyzing water quality.

The 80-cm (31-inch), 12-kg (26-pound) fish has a white body with bright red spots. Though the tail movement is very smooth and lifelike, the remote-controlled koi is capable of moves that a genuine koi is unable to perform, such as swimming in reverse and rotating in place
