So, my first thread is going to be one of the ones I imagine every asks about. I think I'm happy with the answers I found via the forums, but I'm not exactly a boffin in these areas. Give me java, sql or even pascal and I'm happy as a kitten in my wifes b... Erm. Anywho...
So, I'm looking at one of my early additional purchases being a rechargable battery pack of some sort. The kind we'd find in a good RC car. As I understand, I'm looking at a 5-17v, though from what I've read, ~7v is my best bet?
Is this a suitable kind of thing:
Thanks for any input.. I've got a little wait until my EzB arrives, but it doesn't hurt to find out in the meantime
Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.
A 12v auto battery would work too, in fact, any source between 5 & 17v will work, 7v is perfect for EZB, if running motors you may want to look at the voltage for those if planning to tap off of the same battery. If having an on board PC the 12v is an idea and then use an automobile PC charger to power it...
The thing to think about is how much space is available, how much weight can the robot manage and how long do you want the robot to run before needing to be charged.
So far as what I need power wise at this point, frankly, I haven't the foggiest. I've dabbled (Read: Broke an RC car) in this sorta thing, but my mind is a blank canvas right now. I love the mars Rover type robot someone on here has put together, and I'm thinking along those lines for now.... I think.
Adding more capacity is easy in the future anyway, simply add another battery in parallel, or two. So at this stage you'll be fine picking up just 1 battery, getting the robot built and then you will see how long it lasts on the one battery, if it's not long enough just throw in another, or two more.
