WHAT ARE WE BUILDING?
Though taking control of our robotic arms can be a lot of fun, now that
we have a set of equations that can move our end effector wherever we’d
like, we can leverage the fact that your Arduino can do these kinds of
mathematical equations much faster than we humans can. In fact, if we
add a few more bits of code and maybe even a little more simple math, we
can get our robotic arm to do things we could never do—or, at least, that
would take us much longer to do. Thanks to the magic of inverse kinematics,
we can now make our robotic arm draw shapes, make pictures, spell out
