Hello there, I just want someone who has worked with robotic arms before....I have an essential mechanical question...
If i was going to implement Motors for the movement of the wrist and the fore arm, would it better be to put them both at the shoulder's position, and link each motor's axe to a gear, and a chaine the elbow so that I can move the wrist, and the other motor will use another chaine that will be normally shorter than the other, and which will be used to rotate the fore arm ??
2nd option:
I will put a motor on the junction between the fore arm and the shoulder, and another one at the elbow's location to move the wrist directly with no chaines or gears used...
My last question will be:
Would it be better to use servo motors, or Stepper motors ? cause I will be measuring the tilting angle of each body part.
