The overall objective of the thesis is to design a robot chassis frame which is a bearingstructure of a vehicle supporting all mechanical components and providing structure andstability. Various techniques and scientific principles were used to design a chassis frame.Design principles were applied throughout the process. By using Solid-Works software,virtual models was made for chassis frame.Chassis frame of overall dimension 1597* 800*950 mm3 was designed. Center of mass lieson 1/3 of the length from front wheel at height 338mm in the symmetry plane. Overall weight of the chassis frame is 80.12kg. Manufacturing drawing is also provided. Additionally,structural analysis was done in FEMAP which gives the busting result for chassis design by taking into consideration stress and deflection on different kind of loading resembling real life case. On the basis of simulated result, selected material was verified.Resulting design is expected to perform its intended function without failure. As a suggestion for further research, additional fatigue analysis and proper dynamic analysis can be conducted to make the study more robust.
