Servos Run In Wrong Directions?

Skip to comments   Jump to end

I'm 3D-printing the parts to build the humanoid robot. I followed the instructions on building the robot but my own servos with metal gears run in wrong directions. For example, I told the robot to take a bow and the robot bows backwards instead of forwards. I thought that all servos MUST run in correct direction. Any suggestions?

Something to consider! Ezrobot servos are designed for the platform and tolerate 7.4 volts

We can also not guarantee that reversing directions will result in the same servo positioning of after market servos.

Is this correct when inverting directions?

180 - incorrect value = correct value

For example: 180 - 150 = 30
