Let's Make Robots!

picky motors?

 So I'm a complete beginner at this. I know ohm's law and generally what components do, but I've never tried to put anything together yet.

Electric Bike - WIP

I'm starting work on an electric bicycle. I put an ad on Craigslist last night for a bike in any shape - and ended up getting two bikes for $20 that are in pretty good shape. One is missing a pedal... but that's all.

Hexapod Dance

Found this on www.roboticsindia.com . It must be pretty tough to make and programme such things.

Hehe, found something funny on youtube!

Hi everyone,

Whilst roaming on youtube, I found this kick-ass vid about CtC's first atempts at programming a PicAxe microcontroller... Little contrast to what he is up to now with Walter :p

N-joy

how to charge my robot's NiMH battery 24H/24

I hope your attention because I'd like your advice on how to load it !

Let's me explain:

I have a charger with delta peak A2Pro that loading my battery "when robot off . " http://www.net-loisi...peak-p1441.html

My goal is to let my robot over 24h/24 in order to use it when I want . "I did a test to determine the robot turned on autonomy without running , it is 8H . so if I go one week it is off !!!!"

Running a MicroController off a SuperCap

Because I keep daydreaming about wiring up my house with dozens of sensors, I was wondering how hard it would be to power a micro controller (say picaxe) off a super capacitor.

A supercap is an electrolytic capacitor with an insanely large capacitance. Mine is half a Farad, 470000 uF. But is rated for only 5.5 V. That's the deal with these caps. Higher capacity at the expense of the maximum voltage they can endure. Or simply at an expense. This one costs about $4 at DigiKey.
