We attached and corrected the front and back modules and attached them to the chassis. Hence our chassis was completed.

We made the front and the back modules of our chassis.

We completed the central portion of the chassis.

Today we completed the base of the chassis.

Today we went for shopping for rivets. We were looking forward to working with rivets, but the rivet gun available in the club was faulty and hence, our work got delayed by yet another day. We decided that we'll work in Tinkering lab the next day. We also tested our GPS module and found that it was quite accurate.

We started making our chassis using nuts and bolts. It took extra bit of effort from our side doing this and also due to some alignment errors, we were able to complete only a small part of the chassis.

Today was our project evaluation. Due to the unavailability of rivets, we were suggested to make our chassis temporarily using nut and bolts and then rivet later. We were also given suggestions regarding our mechanical design.

More of our mechanical parts were received today. But, due to the unavailability of rivets, we couldn't resume our work. Also, the bill of Ardupilot wasn't cleared.

The bills of the mechanical parts ordered were cleared and hence the machanical work started as we cut the Aluminium tubes according to the dimension needed. There was no progress in electronics as the bill of Ardupilot wasn't cleared. Our further mechanical work was hampered by the non-availability of rivets. 

We received the Ardupilot today. Hence, we started researching on its connection and communication with Arduino, Mission Planner and its power requirements. We also contacted seniors for help. But, again due to the fact that the bills weren't verified due to the absence of the authorities, we couldn't either start our Mechanical Work or start using the Ardupilot. 

We went for shopping to purchase Mechanical parts required for the construction of our part. Also, we found and studied Github repositories for PID implementation and Communication of Ardupilot, We also planned to start our Mechanical construction work, but due to the fact that the bills were not verified, we had to cancel our plan.

We faced many problems in reading about PID and Kalman filter. The codes were difficult to understand and quite lengthy. Hence, we started by reading about there applications and the theory behind the algorithms. On the other hand, our mechanical design was nearing completion.

As almost all the components were fixed, we started studying about the various components. Also, we started learning how to implement PID and Kalman filter to filter out the errors in the movement of our bot. We also started looking for libraries of the components ordered to simulate them in software like Proteus.

We started finalising our components and ordered Ardupilot and Dampers. We also started making the mechanical model of our bot in Solidworks.

We broke down our work into 3 parts - Mechanical, Electronics and Programming. Then, according to our needs, we researched and selected the components that we would require. We had to take in account the respective individual qualities as well as the ease of integration with other spheres of work while selecting a component.
