For my robot, I am using two continuous rotation servos to spin a threaded rod. I am trying to make this project as cheap as possible. Here are the servos that I can find:
- Servo #1: This is a very cheap option and it has half of the torque I need.
- Servo #2: This has all of the torque my project requires, but it is much more expensive that two of servo #1.
Can I hook up two of servo #1 to each end of the rod and have them move synchronized? I can spare a few extra pins on my microprocessor that I am using; that isn't a issue. I know hooking two together will increase torque, but I don't want 75% of the torque I want in this situation. Also, I don't care if I only have 98% of my torque "goal" with the extra weight (which probably won't happen) but I don't want to, like I said earlier, have 70, 80, 90% of my "target goal" of torque if possible.
Any help appreciated. Thanks in advance.
Method 1[of 2] it said "Use only if the servos travel the same distances. (Most don't!)" What does that mean? The reason I ask is it must have some benefit and it seams a little easier to build... but I wouldn't mind if it was better (reliability, etc.). $\endgroup$
