182 Make: Robotic Arms
WHAT ARE WE BUILDING?
Now that we have fully integrated our inverse-kinematics code for our
3D robotic arm, we can add one of our previous methods of input back in:
the rotary encoder. In the previous chapter, we used the rotary encoder to
directly control the angles of each motor. This time around, we’re going to
use it to influence the value of our target (x, y, z) coordinates, giving us a
different and much more accurate method of controlling the position of our
robotic arm’s end effector. In this project, clicking the push-button will toggle
through the x, y, and z target values, and the knob will either increase or ...
