My application is a small robot-ic head - lets say for a scarecrow. It is going to be moved around frequently, during operation too.
I obtained a lot of these "hobby" servos that are used in RC planes/cars/helicopters...
My problem begins here - when I tried to fabricate the head using the design I had in mind, the model came out heavier than I expected.
Now on paper these motors (TowerPro MG996r CLONES) have good torques, but I want to believe during operation they might burn out and I will be left with a dummy head in one hand and resignation in the other.
So I thought I will use 2 motors for one axis. The motors will have to be coupled but at the same time facing each other - which means they will have to run opposite to each other.
I am thinking of using some aluminium couplings on one of the motors to reduce backlash. Software will have to be modified to (as close as possible) send opposite signals to both the servos... so that their torque actually helps each other.
Now for my question: Does this all make sense? Or is it not possible even theoretically? Is it a stupid idea?
P.S.: I am using a Pi-zero W (ABSOLUTELY LOVE IT) and a PCA9685 servo controller board (clone again :( ) - for information.
Thanks a lot O' lovely forum. I am getting entertained and educated going through all of the posts, hope to contribute soon.
