Numerical kinematic and kinetic analysis of a new class of twelve bar linkage for walking machines

19 November 2008 (has links)
M.Ing. / This study describes a new class of mechanism to provide leg like motion, for use in a new type of walking machine, that is larger and simpler than electromechanical machines that are currently available. The mechanism is located in a historic context, and current technology in this area is reviewed. The problem of calculating the geometry of the complex mechanism is solved using an innovative solution based on coordinate geometry, which may be extended to solve other planar mechanisms of either greater or lesser complexity. All assumptions have been detailed. The analysis covers both the motion and the power requirements required to make the mechanism move. Structural aspects, which may affect any practical walking machine, are covered. A software implementation has been developed, providing output to demonstrate that the model developed reflects reality, within the limits of the assumptions made.

A new type of walking machine

Ingram, Anthony James 10 June 2008 (has links)
This thesis introduces a new type of walking machine that appears promising due to its relative simplicity and efficiency. After an introduction to a selection of previous walking machines, the new machine’s history, advantages, operation and a method for solving its kinematics are given. Early attempts to optimize the mechanism to a range of criteria are described and their shortfalls exposed. A second attempt to optimize the leg geometry by genetic algorithm is detailed and the results of this search discussed. A mechanics model of a hypothetical machine is developed from first principles and the implications of the analysis described. Stability limits and tractive abilities of the machine are explored. A method for determining the loads on the links that constitute the leg and the vehicle chassis is given. A series of prototypes has been constructed and discussions of these machines are given. The most recent prototype is used in a pair of experiments to validate the kinematic and kinetic models. The experimental method, a statistical analysis of results and a discussion are provided for each. The thesis concludes by considering what work remains to be done before a practical cargo carrying transport walking machine can be designed. / Prof. A.L. Nel
