help me! robotic ponter
hi all!
I am currnenty working on a robotic pointer that can point any point in a x, y coordinate plane. for this i am using a structure with two platforms one on another. the platform at the bottom is attached with the platform on top of it. while one platform rotates in the x-axis another rotates in the y axis. thus enabling me to get all points. the pointer must point using polar coordinates, that is using degrees. I am trying to mechanize and computerize this here i am suffering some problems.
1. how can i turn the platform by degrees accurately? (a small mistake and the point will not be marked properly) for trying to turn the platform should i use gears? if so what will be the best ratio to turn by .5 or 1 degrees?
2. can stepper motors help? My sir adviced me to use them but i have no proper idea how to implement them.
3. how can i computerize it? i am aware of using serial port for interface and have already gone through many circuits but without the above solved the rest is in vain.
Hope u will help and suggest me.
Thanks in advance for the help.
