What are the most significant risks that could jeopardize the success of the project? How are these risks being managed? What contingency plans are ready?
One very significant risk is that our scope might be too large. Getting the controls, object detection and SLAM working on a single robot is a larger feat than we imagined.In particular, it will be difficult to fully implement SLAM in our system. We are managing this risk by talking with our Autonomous robotics professor who is experienced with the Jetson Orin Nano and Issac Ros. For example, he guided us with the setup of the object detection library and told us about the need for using an SSD. Depending on how much time we have remaining before our final submission, the contingency plan would be to scale down our localization and use April tags in a small defined environment, rather than a generalizable search algorithm that works in any place.
Were any changes made to the existing design of the system (requirements, block diagram, system spec, etc)? Why was this change necessary, what costs does the change incur, and how will these costs be mitigated going forward?
Not a change but we have realized that we need the Raspberry Pi and cannot eliminate it as libraries that could be used to eliminate its need don’t work effectively. This realization occurred after having spent significant time working towards eliminating the Pi and hence was a costly mistake in terms of. time. However, since we already posses 3 pi’s we don’t require any extra expenditure to use them.
