Let's Make Robots!

YES it's a robot, NO it doesn't have a microcontroller

I think we need to get of our high horse here and let snyde remarks regarding our own elitism remain silent..

I have seen several comments here stating that a robot has to have brains to be a robot. Now, where is that rule written in stone? Does it have to run around on tabletops, using skid steering, detecting cereal boxes by IR or ultrasound, have blinking LEDs or follow black lines on a piece of cardboard to be a robot?

Here is a quick walk-through on how to get your hands on a really cheap alternative to the GM10s. The motors you get here are not even nearly as cool as the GM10s, … Read more

Robot challenge $100 prize

Crabfu is inviting us all to a $100 challenge. Whoever makes the robot with the most "life".. He wants us to make robots that gives an illusion of character, like cute/bad-ass/mean/angry/cheerfull/nervous or something completly different.

Go ahead: impress, confuse, bedazzle and surprise the judges, and you could win $100 worth of stash from Trossen Robotics.

self balancing bot

check this Self-balancing robot on instructables. It doesn't stand upright for very long, but it's a very good starting point, IMHO.

stepper motors

I ripped apart a couple of flat bed scanners looking for gears. So I have two stepper motors in my kit box that takes up valuable space. If anybody got inspired by this and want to give stepper motors a shot, just give me your adress and I'll send one your way for free in about two weeks (vacation atm).


Hot melt glue sticks

I Have bought some 5/16" diameter Hot Melt Glue Sticks for a hot glue gun. That's not the size my gun uses. If anybody wants it, just send me your adress and I'll ship it to you for free. They're dirt cheap anyway, but I thought I should ask...

pager motors (still inside cell phones)

I have some gutted mobile phones (mostly Nokias I think), so I can part with:


surface mount LED's

motors (same as inside the GM10's)

speakers/mic's (the speakers used for the ring signal are small and obnoxiously loud, but need a strong amp)

These are the parts I instantly recogniced as usable for roboteers, but the phones are basically just partly disassembled but complete, so there are obvious more parts than the ones mentioned here.

management model


The Decepticons robots are far superior to the Autobot robots. Their only real problem is the management model applied by Megatron.

The Autobots have weaker and less agile robots, but still manage to outmaneuver the Decepticons by Optimus Prime's abillity to forge the Autobots into one co-ordinated unit.


I love the look of Polymorph. It's a plastic material that becomes soft like dough at only 62 degrees celcius, and remains shapeable until it cools down to around 50 degrees. under that temperatur it behaves like normal plastic, you can cut it, drill in it, glue it together, sand it and paint it. And if you need to reshape it; just dip it in your teacup until it gets hot again. For more details check this PDF on specs.


Here's my entry to the robots in the sun.

If anybody would donate some small plastic gears for my toy competition entry, feel free to contact me, OK
