Ok, I started another post simply because this is onto a different topic in my construction. Ultimate idea for now is to construct a four legged walker with a camera, a few distance and infrared sensors for motion tracking and knowing when a wall is nearby. The child in me wants to stick an airsoft gun on it as well...
Nevertheless, I now have a UNO board with a starter pack with things to play around with, and I think I got a decent handle on how to operate various gizmos. Now I want to get started on my robot by making the four twist and lift servo combos that will rest at each corner of the "body" for the four legs.
Here are the supplies I'm looking at: Shield: http://emartee.com/product/41953/Sensor%20Shield%20V5.0%20%20Arduino%20Compatible Servo Possibilities: http://www.hobbypartz.com/37gexidised11.html http://www.hobbypartz.com/33p-solarservo-d222.html Pan and Tilt Kit: http://www.robotshop.com/lynxmotion-pan-and-tilt-kit-aluminium-1.html
I was planning on using the same servos on the leg's mid-joints, with metal legs, 3-4 inch segments. I'm not yet sure how much the body will be carrying, but it will have my camera (weighs probably 10g at most) the UNO and shield, metal chassis, at least 2 distance and 2 infrared sensors, battery pack. The airsoft gun is still optional, but will definitely be the heaviest.
From other opinions and research, I've been told that controlling 12 servos with the arduino board has a power issue, and am curious that it's the same way with a shield.
Anyone have any opinions on this? Thanks!
