|The Turbot page
Turbots are strange critters, moving like nothing else. Turbots are fairly
slow, but what they lack in speed they more than make up in capability. I
have a few more turbots that I will eventually put up when I get the time.
In the summer of 2000 I did a fair bit of time-lapse of some slower solar
powered Turbots. The time-lapse did show that Turbots can be made
phototropic, up to that point I had yet to see any conclusive evidence of that.
Recently been experimenting with battery operated turbots.
Also included here are a pseudo Tubot like bot I called a "Turmet" its sort
of a cross between a Tubot and a Symet. Its surprising how capable these
little guys are, I don't recommend leaving them alone the vicious little
raptors they can be.

addition to the Turmet family the main difference is the GM11 instead of the
GM12 (from the old solarbotics miniball kits) Makes it quite a bit faster
(should be 1.77675 times faster actually).
I provided a few construction detail pics for those that want to build
one of your own.
1*1381 "C" trigger (want a low Vtrig when the solarcells are parallel to
1*3300uF cap (nearly the exact diameter of the motor)
1*0.47uF cap (actually used a 1uF SMT cap but 0.47 is also fine)
I used stainless steel (316 high chromium) for the arm and silver
soldered it to a wheel collar (1/8in IIRC) The joint is strong enough that
the steel around the joint will break before the joint does. This does
require a blow torch, pickle pot, and some special flux so for ease of
construction just use brass, bronze, steel or another material that takes
lead based solders. The wheel collar is chrome plated brass and takes
regular solder quite well.

Here is one of my older attempts at a
Phototropic solar power turbot. I did include a 3.6V 60mAH rechargeable
battery for battery operation. I used mostly silicon bronze for construction
and really high quality gear motors, ironically too high quality I have to
change the circuit a bit to accommodate them.

"Turmets" what? they are a combination of the turbot and the symet
henceforth the name. These little guys are vastly more capable than a regular symet and
as I found out they are vicious in a slow sort of way.
For circuitry these just use the simple, reliable and efficient Miller
The first Turmet I built was similar to these but was stolen at a
BEAM workshop and never returned. It's ok tho that's what motivated me to
build these two.
Story of the first micro turmet:
I left my finished prototype on my workbench and went to work for the
day when I got back the Turmet was happily chewing up a nice space grade
solarcell. What happened was that the sun hits my workbench during early
spring and winter, Turmets just eat up the sunlight and become relatively
active. So it slowly made its way across my workbench and got tangled on
the solarcell wires. It eventually reeled in the solarcell and proceeded
to break it into a few pieces. Too bad the one that did that got stolen, I kinda

The first tumet,
its kind of a cross between a turbot and a symet. Not very fast but very
capable at getting over rough terrain. Originally this was built to see if a
solar engine could be squeezed into the space inside of a servo... it can
and easily too!
It can't be seen but there are solar cells on either side of the servo,
so when it flips over it will still be getting power.
Simple, small, capable and vicious I like them.
