The main risk at this point is that we are still working on the details of how many of the systems will work, and we aren’t yet sure what problems will arise as we try to implement our designs. For example, we are still figuring out exactly how the pathing algorithm will work and where the robot will decide to go (though this will come into more focus once we have an initial version of the SLAM system completed so we can see exactly what the input to the pathing algorithm will look like). To manage these risks, we plan to start implementing our software on the actual Raspberry Pi so we can refine the designs by seeing how they will be implemented. We have ordered the Raspberry Pi and it is ready for pickup from the ECE Inventory, so we can get it first thing Monday morning.
Last week a lot of the design was uncertain, but we have worked a lot more on the design for the design review presentation. There have not been any major changes to the design since the design review presentation. However, we are still working on refining our design and going into greater detail for the design review report. There have also not been any changes to the schedule since the design review presentation.
