https://doi.org/10.1057/9781403938657At the beginning of chapter 4, we stated that Ball’s instantaneous screws are rays through the origin in the Lie algebra .(3). Clifford referred to the elements of the Lie algebra as motors. In the following, the practice of referring to Lie algebra elements as screws will continue, with the hope that no confusion will arise.

Introduction,Although modern industrial robots are only a few decades old, their antecedents are mechanisms and linkages, which have centuries of history. Indeed, examples like cranes and other lifting devices are among the oldest machines used by humans.

Screw Systems,At the beginning of chapter 4, we stated that Ball’s instantaneous screws are rays through the origin in the Lie algebra .(3). Clifford referred to the elements of the Lie algebra as motors. In the following, the practice of referring to Lie algebra elements as screws will continue, with the hope that no confusion will arise.

Differential Geometry,This final chapter is slightly different in character from the preceding ones. The aim is to present some less elementary examples. The examples are loosely related by their use of some concepts from differential geometry, hence the title. We will begin by looking at some differential geometry on the manifold of the group .(3).

Hans-Bernd Schäferso far. The main bottleneck in successful utilization of PHAs is their high cost of production. This book chapter presents general introduction on PHAs and their types, and how they came into existence.
