KINEMATICS FOR
2D MOVEMENT
I
n our previous chapter, we began by
assembling our first robotic arm. Next,
we wrote a few software examples
designed to control the servos used to
move the robot. Though independently
manipulating the two motors of the robotic
arm is fun, it highlights an important
question when it comes to robotic arms:
What if I need the end of the robotic arm to
point to a specific location? The goal of a
robotic arm is often to grab, manipulate,
or interact with objects around it, so
how does a robotic arm know how to
move to specific locations?
