Advice on building a pan/tilt robot arm
March 18, 2011
Hello LMR folks,
I am in need of some advice over a robot project I plan to build. I have a small amount of experience with using an Arduino, soldering and general circuit making, but I've never used motors yet.
What I plan to do is to have a "robot arm" attached to the ceiling with a camera at the end of it. The arm need to be able to rotate the camera around and depending on some conditions tilt it at different angles.
I was thinking of driving the entire rig with an Arduino Uno and using a pan/tilt servo combination from DAGU (this one : http://robosavvy.com/store/product_info.php/products_id/1182 )
My main questions would be the following:
- Can the arduino control and power both servos ?
- Does it need any extra circuitry to do that ? (e.g. a motor controller, something to protect it from back current from the servo, etc...)
- Most importantly, would these servos be good enough to handle a camera that weights 250-300g ?
- Can the pan servo handle 360 degrees of rotation (it doesn't need to be continuous, i.e. moving 0 -> 360 -> 0 is fine) ?
Thank you in advance for all your answers
