1 1. Final Management Report This brief report summarises the progress made by the group throughout the project lifecycle. Initially, it was agreed by each member of the group that the best way to initiate the project was to carry out an initial assessment of the task at hand. The assessment was to establish the following points: ¾ ¾ ¾ ¾
Association of the vehicle’s subsystems to each member The terms of reference for the 2010-2011 CAD3 Group Agreement on the overall themes of the design A published list of the project management schedule.
From this, a weekly meeting was suggested and agreed by everyone. Each member of the group had opportunity/opportunities to chair/secretary the meeting. From these weekly meetings, the progress of each member’s designs was discussed and in cases where there was a decision to be made outside direct collaborations; it brought up at this point.
2. Progress of the project 2.1.
Design Methodology
To start off the project, the footprint of the overall car was established from which subsequent individual designs adopted the dimensions. From this, a chassis template was determined and each individual had to enter their relevant positional reference associated to their individual elements. Over a period of time, the progress of the assembly came together. General assembly was controlled through a digital drop box that was set up on the BlackBoard website for the CAD3 Unit. Through this method, every member had an opportunity to post their parts and subsequent methods of assembly so that the parts can be mounted on the assembly. Components having been completed/nearly completed, an appointment of Assembly Co-ordinator (Arvydas) was made. His role was to liaise with each member of the group about the position of their parts and any issues with assembly and would subsequently update the chassis as to be seen in the following part of the report.

5 5. Further Developments and Recommendations Overall, the project can be deemed to have been a success. This is evident from the ability of the group to produce a complete model of the car. There is however, a further need for some developments to be made on the model produced by the group. This is due to the fact that as the project progressed, there are a few compromises and assumptions that had to be made for the assemblies to come together. Examples include:
¾ Tyres ¾ Battery Pack ¾ Body Shell ¾ Fuel Tank ¾ Exhaust Pipe
Some more work could be carried out on the above mentioned parts and could subsequently determine the overall layout of other parts and most importantly, the integrity of the complete model. Further development must also address issues such as safety; i.e. front and back bumpers to protect the car from direct collisions.
