Sprockets and Gears

Where are some good online stores to buy sprockets, gears, etc. from? In small and large sizes.

hello everybody,

This is my "Start Here" robot. I got the parts from Solarbotics in their kit. I have always wanted to build a robot and I didn't think that I was smart enough to … Read more

What's ignoblegnome building?

Any guesses what I am building? Sound like a fun game to play?

I am anxious to hear your guesses.


Update: An easier way. 

TheAndroidMan posted a tip/walkthrough on adding pnuematics to a robot. That will make this project much easier.


Update: The answer!

nanoDuino, sumo and soccer bots

Hi Everyone,

I'm starting with some new projects.

The first one is nanoDuino, an ultrasmall arduino, based on patrickmaccabe's one. This one has all the input and output's pins broken out and the sockets for FTDI and ICSP cables. It is 18,5x20,5 mm:

Lunar Rover

Hi all,

Just want to share some videos of a moon rover study I am doing for the Google Lunar X Prize. No time now to submit a robot project entry, the rover is quite complex, maybe later. I'll add videos here as they come along. Thanks for watching.

 

Rover 5 - 4 Channel Motor Controller: PWM Frequency

I just got hold of OddBot's Rover 5 platform and the 4-Channel Motor Controller.  I'm still fairly new to all this and I'm not sure what PWM frequency to use for the controller.  The datasheet that I have doesn't specify so I'd appreciate any advice you can give me.

Many thanks.

Robot Vacuum Cleaner

After doing some searching the last few days I've found that either there is very little information on people who have created their own autonomous vacuum cleaners, or iRobot has done an amazing job at taking up a vast majority of searches on the subject every place I've found. Given the high cost of the Roomba, and the relative cheap-ness of robot parts, this is surprising to me. I've seen posts for the crumbot, and the post for the bot using that $7 mushroom vac from dealxtreme. So I'm wondering, is there any more information available?
