I need to have a pan-tilt mechanism built this week but I was having some issues with choice of servos, and so I was hoping someone could help me answer some questions.
Some background information: The system needs to pan 360 degrees, tilt 180, and have a resolution of 1 degree or less. I bought continuous rotation servos previously without knowing I sacrifice position control, and had to send those back. For the tilt, there are 180 degree servos that meet the requirement so that shouldn't be an issue. It's the pan that's the issue.
I was looking at this product from servocity: http://servocity.com/html/gdp985a-bm_pan_system.html , and I had a few questions. Firstly, how does it rotate 450 degrees? Does that mean that upon reaching 450, it will return to the neutral position and cannot continue rotating in the same direction? How does this servo even exist, as from my understanding, no conventional servos can rotate more than 180 with position control.
Is there any way to get information as to the resolution of this servo from the given specs? I just need to be sure that it has 1 degree of resolution or less.
Can this product be controlled like every other servo using an Arduino controller? Will I run into any issues programming it?
Do you think this product should work for my purposes? Are there any glaring issues that I'm missing? Apologies for all the questions however I'm on a hard deadline and would like to get this right :)
Thank you for your help in advance, much appreciated.
