constructed with three groups of two-link pairs. In some ways, it as if we

created three versions of our first two-link robotic-arm design and gave the

three arms a common end effector.

Delta robots might look strange, but they are known for their speed and

accuracy. In fact, they are so fast and accurate that some companies

have used the delta robotic-arm configuration within 3D-printer designs

to achieve faster print time. Though the kinematics of a delta printer are

slightly more complicated than some of the robotic-arm designs we have

discussed in this book, the underlying principles are similar. The delta-robot

arm ...
