Three Degree-of-freedom Optical Orientation Measurement,achieve a high-precision measurement result, and its performance is not affected by environmental field. The algorithm for three rotation angles has been derived. Two experimental apparatus have been developed to conduct measurements, and to evaluate the proposed orientation measurement method.

Hemiplegia

Introduction,n precision, fast response, direct driven, non-singularity in workspace and high efficiency, it has wide potential applications in robotics, manufacturing, automobile, precision assembling and medical surgery. The fundamental concepts and working principles of various spherical actuators are present

Torque Modeling,of the PM-pole rotor is formulated based on Lorentz force law. This torque model relates the torque output of the spherical actuator to the current inputs of coils and the rotor orientation, which indicates that the torque output of the PM spherical actuator is orientation dependant. Nonsingularity

Prototype Development,ed for conducting experimental works on magnetic field distribution as well as actuator torque output to verify the derived analytical models. This chapter discusses the prototype development of the PM spherical actuator with detail considerations in the design of the rotor poles and stator poles.

Experimental Investigation,el and torque model proposed in Chapter 2 and Chapter 3. The experimental investigation of the PM spherical actuator consists of two major tasks: measurement of magnetic field distribution and torque variation.

Three Degree-of-freedom Optical Orientation Measurement,nt measurement method for 3-DOF rotational motions. The operating principle of the measurement method is based on the non-contact laser detection. It has several advantages compared with other orientation measurement methods. The non-contact property avoids friction and additional mass/inertia momen
