178 Make: Robotic Arms
WHAT ARE WE BUILDING?
In chapter 6, we saw that once we had the inverse kinematics for our four-
link robotic arm, we could program multiple sets of coordinate points to
accomplish tasks such as drawing shapes. Now that we have built our 3D
robotic arm, we can draw 3D shapes. In this first example, we will draw a
3D cube, but keep in mind that this same code can be customized to serve
as a series of points to pick up objects and place them in other locations—a
common task for robotic arms.
Now that we have a 3D robotic arm, we can create movements that fully take
advantage of the extra dimension of movement and degree of fr ...
