Last week I built a little non-robot vehicle using four of the new
internally geared-down Technic 9v motors. Two of the motors were connected
directly to the wheels, the other two motors served as human-cranked
generators to power the motors on the vehicle. The reason I used four
motors (two pairs) instead of two motors (one pair) was so that I could run
each of the wheels different directions, so that the vehicle could pivot in
place and turn.
Anyway, a really fun experiment that kids and adults alike seem to enjoy is
simply to hook two 9v motors together with a regular connector. Then turn
one motor and watch the other one turn in perfect a mimic. It's really
amazing how energy-efficient the LEGO motors are.
Jin Sato did something even neater yet -- he made a little walker vehicle
using two motors -- one as a generator, the other as a motor. The feet were
the "claws" (opened wide) from an Aquazone set such as 6109 Sea Creeper:

The mechanism worked magically -- you turned the generator motor back and
forth, back and forth, like a washing machine, and the walker took little
steps. I think kids would love seeing something like that.

One other idea on that same line of thought -- the very first thing I wanted to do as soon as I got the two motors hooked together and working (which really only takes a couple of seconds) was to make the wire longer -- to put more distance (...)

| (...) Cool! I'd never thought of doing that. Just showed it to my daughter and she was very interested and we had a good conversation about motors and generators a a result. I'll show the kids when I go in next week and see what results. Kevin (25 years ago, 30-Oct-99, to lugnet.edu, lugnet.technic)
