The Foundation for CADSPAM: Computer Aided Design of SPAtial MechanismsDoyle, Matthew Edward 17 December 1997 (has links)
This thesis presents the foundation of a computer program for the unified design of spatial mechanisms. The program will be capable of synthesizing any mechanism that can be described using an equivalent chain containing only revolute and prismatic joints. The supporting analysis routine will be general and will be able to analyze any lower pair mechanism using the iterative approach developed by Sheth and Uicker [1972].
Unlike precision point synthesis methods that allow only a limited number of positions to be specified, optimization will be employed to synthesize a wide variety of mechanisms. This approach will allow the user to interactively monitor and control objectives and constraints, which will yield practical solutions to realistic mechanism design problems.
The creation of this program will provide practicing engineers with the capacity to design many previously intractable spatial mechanisms. / Master of Science

Control of modular robotic fingers toward dexterous manipulation with sliding contactsGrier, Michael Anthony, 1956- January 1989 (has links)
Control and other issues related to the use of modular robotic fingers to perform dexterous manipulation are considered. The specific manipulation strategy to be implemented, which focuses on parts acquisition and takes advantage of sliding contacts which exist between the fingers and the object being manipulated, is described. The results of early implementation efforts are discussed in which a standard individual-actuator PID control approach was used. Problems related to friction and other effects are identified which were encountered in these early efforts. A computed torque control scheme which provides adaptive friction compensation is proposed for future use with the fingers. Results are discussed of simulations performed to help determine if use with the fingers of this proposed approach will improve system tracking performance in the presence of a variety of disturbances like those which will affect the fingers during actual operation. Implications of results for future implementation efforts are discussed.
