Hey everyone, so I made a prototype robotic arm today with micro servos.
I got it working and everything after several hours of cutting, wiring, and hot gluing.
I still have one question, on which was probably the hardest thing I encountered today. How can you tell the range of motion of the servo?
My servos (SG 90 micro servo) have a range of 180 degrees, so I thought it would be simple. I attached the servo horn, mounted it temporarily to its location with mounting tape and used that as a guide to determine its range of motion for when I mount the acrylic pieces that I cut.
Anyways, I got a good range estimate of how far the servos could turn by doing this, but is there any other way to determine how far servos can rotate? Do I have to attach some object to the top and determine its rotation from 0 to 180?
