Easy Cheap Power Control, Distribution & Charging for Large Robot

Since I primarily build large robots, I have always had issues with power control, charging, & extending battery life. I use large gell cells and it seems like I was always either over-charging them or not charging them often enough and they would die prematurely.

It occurred to me last night that instead of trying to design & build my own power controller, (which I've always done in the past), that the answer to my problem might be as simple as an off-the-shelf unit designed for solar power systems.

Very Very Cheap Platform

So, I was starting on building my second robot, and I didn't really find enough materials around. I found straws and chopsticks, so I cut them up, glue them, and made them into a cheap base for my robot.

Free Motor Controllers!

I am currently designing some very budget friendly Motor drivers, and to test the design out, I am giving away 10 free drivers! Each driver is a single or possibly dual (5 single and 5 dual) transistor based design, and cost per board is very, very low. If you would like one of these free driver boards, please post in the forum below. No restrictions! Each board ships with a application note so you know how to use it.

A few specs:

Max Voltage: 30V

Max Amperage: 0.6A

UPDATE : I've made some changes. It's smaller but for a dumb mistake now it's unstable, working on that! For the Motor Controller I'm using a L293D with a … Read more

Uber cheap build idea, needing input...

I'm looking to build an uber-cheap robot arm, with the purpose of just sitting on my desk and picking up whatever i want it to... Probably stick with a basic control (independent forward, off, reverse switches on each motor) setup. What i'm trying to figure out is, I'm planning on using a standard 3 wire (forward, ground, reverse) style motor similar to that found in a cheap rc car, yet i can't find any places to buy them, except in the cars. any sugestions?

VB programming help wanted! Plotting serial data.

Hi guys, I`m attempting my own low speed arduino oscilloscope but have hit a brick wall with my mediocre programming skills. The arduino program and input stage works fine, it`s the PC software thats killing me.

Tools & metal for building robots CHEAP!!

If you ever need metal working tools or pieces of aluminum, copper, brass, steel, or stainless, cut-to-size and shipped at reasonable prices, please check out: http://stores.ebay.com/Stoners-Tools-and-Raw-Materials?_rdc=1

He has hundreds of stock sizes and shapes in stock at his on-line store, or he will custom cut pieces to your size for only $.25 / cut. Paul Stoner is a super guy to deal with, easy to communicate with, and gets your parts shipped right out.

20Amp Motor Driver/Controller

I am looking for a 20 amp motor controller/driver. I prefer an IC, that way I can integrate my own driver circuitry, but if it is cheap (under 50) post it. I'd prefer if it could provide 20 amps per channel. It will be operating on 12VDC.

Basic platform - On the cheap

Hi, I'm planning to make a small set of self designed swarm bots.

 In terms of a mechanical platform, what's my best bet. My criteria are cheapness and easiness. Ideally, it should cost < $25 per platform, and be easy to make.

 So far, I'm thinking of pairing two solarbotics GM9 gearmotors and wheels with a thin wood base, and a third caster-esque wheel.

 Is this the best way to go?


 hello everybody here...!!!

Actually m from india . speaking straight, " i can't spend much but also can't live without robotics".

so please give me some advices to not to kill my love towards robotics. i m a student of electronics but here in my college we do not have such facalities for electronics students. so please guide me about how to begin and what resources to use to get over the money problem. 

i really need your help.......!!!!

Hand held battery vacuum cleaner

I bought a cheap battery powered vacuum cleaner from dealextreme to build into Ozzy. The idea was to build a front mounted vacuuming attachment as inspired by emullers vacuum bug. I was pretty skeptical of its sucking power and for about $6 with free shipping worldwide I wasn`t expecting it to be very useful. Now that it has arrived I can say yes indeed it does suck! In a good way!

Heres a small pre-hacking photo review.
