Sources for Motors and Steppers with searchable index?

I am shopping for a motor for a hobby project, but am having difficulty finding a good source, that has a searchable index.

I like RobotShop for its large variety of parts, so that I don't have to pay for shipping from a motor source, a driver from another, etc. But, a list of hundreds of items, with no way to sort them but price, makes the job quite tedious.  The brief description is not really helpful, since it often omits important information, such as voltage and torque.

How to attach BaneBots wheels to motors?

Hi all.  A few years back, I bought a pair of BaneBots RS-775 12V motors in the hope of making a really fast robot.  I messed around with them when I first got them, but did not get good results because I could not find a way to securely attach decent wheels.  I now finally have time to work on it again, and I believe I have a better plan this time.  I would like to use the BaneBots T40 wheels (the 2 7/8" ones) and the matching hubs.  The hubs only come in 3, 4, and 6mm bores, and my motors have 5mm shafts...

Quick research about simulators, please help me understand them

Hi! I'm a designer working in the Open Source Technology Center at Intel and I'm currently studying about robot simulators in order to improve their usability. I would love to hear from you about your experiences in this area:

Where are view counts?

Where are the view counts - the number of times someone has viewed my robots or something elses? Those are always entertaining and keeps bringing me back to my instructables.com and youtube.com dashboard. Maybe I just missed them.

HI Guys!

I try to build my first robot (the robot, which is described on the start page of this website) and i got delivered wrong wheels. There are very small (approx. 2cm diameter) but i need bigger wheels. Did you have any idea where can i order matching wheels for my robot?
