Let's Make Robots!

HEXACOPTER

In film it says the hexacopter left up nearly 6kg(13 pounds) in the air.

That's kinda powerful...

Do whatever you want to add on.
For using this track with timing belt as same way as I did, the robot must be under 30 pounds (As light as possible). It will be very difficult to make turn because … Read more

"explode" array in arduino!?

// My array look like this in string

M.T.M.P. + Grass trimmer

Well... bad choice of the motor I guess. I use 2 brushless motors from a quadroter.

The motor is getting slow after cutting grass for seconds. If I have it spin freely it runs OK as long as it should. Any ideas??

(I use 30C 3S lipo 5AH, shouldn't be power problem. )

Size down M.T.M.P. for test drive

Finally got my speed controller back and have finish the cover case. I kinda quickly assemble them all together and have test run to see if new design has better performance. I am glad it works much better after I reduce the size and sacrifice a lot of parts. (I still like the large size design but it's hell too heavy for the motors I used.)

After I got my controller done I will post detail on robot section. Just wanna prevent updating the old shit again and again on homepage.

useless machine evolved

I think most people has seen USELESS MACHINE already but this one is totally cool but still useless. haha...

Brain wave controlled CAT EAR...

These JP people really have lots of strange ideas. I have hacked one of these brain toys but I dout the accuracy from those sensors. It's more like randomize the output for me.

Question: How to choose the wire?

Yeah, I know this should be the basic question but I flip the page too fast and skip that chapter.

OK, the situation is the wire getting very hot when motor is running. Basically there are 2 sizes of wire I am using, thin and thick. From the image below the battery wire is thick one and the wire on controller is thinner one. Also, wires from motor are thinner, too and that's why I thought thinner wire might work as well? Now, please notice the wire after the connector from battery become thinner, this is the section getting hot when operation is going.

Mobile suit!?

This suit is fun but I guess you need to be train to wear it thou.......Pretty smart design!

Arduino code question and problem.

Can anyone help me to take a look of the code following? CODE 1 works fine to have motor runs forward and backward:
