Hi everbody, nice to be on this forum!
I am a software developer with little to no experience in electronics. Currently I am trying to build a simple robot with arduino as a hobby project.
Here's my plan:
- Base is a Theo Jansen walker kit: http://www.strandbeest.com/shop/index.php
- Two small toy-motors move the walker, one on each side to be able to steer it. This is the exact motor I got: http://www.sparkfun.com/products/10171
- Two sharp sensors provide "vision": http://www.sparkfun.com/products/242
- An Arduino Uno controls the two motors
- Power is provided by a LiPo battery using the LiPo shield: http://www.seeedstudio.com/depot/lipo-rider-p-710.html?cPath=155
- The mechanical movement from the motor is passed to the drive train using a chain and some cogs, I still need to figure that one out...
- This is where I got my idea from: http://crabfuartworks.blogspot.com/2011/02/hamster-powered-walker.html :)
Now so far I have managed to drive the toy motors using a 9V battery, the way it is described in this article: http://www.thebox.myzen.co.uk/Workshop/Motors_1.html.
But since I have the LiPo rider, I would really like to power the whole robot using the LiPo battery. Having the LiPo rider powering only the arduino and keeping an extra 9V battery for the motors doesn't really please me. :~
So I want to ask you: Is there any way I could use the LiPo-battery / -rider to power both the arduino and the two toy motors? If so, can this be done safely, so that the motors cannot interfere with the arduino?
Thanks for taking the time to deal with my noob problem!
