Risks and Contingencies
- The RFID latency is still an issue, but it is something we have decided to address to after the midpoint demo on Wednesday.
- Latency on the video doesn’t seem to be optimizable at all. With basic Vuforia, we have a 270ms latency (without any feature/object detection). Without Vuforia, the latency drops to 200ms, which is still above our requirements. However, this may be the only solution (to just not use Vuforia at all).
- We don’t believe that the rubber band suspension system for the camera is very effective. We will continue to explore this (by trying different slack lengths), but we may just end up mounting the camera directly to the car.
- The motors don’t appear to be as fine tunable as we thought. This may cause an issue in being able to drive straight.
- Our BIGGEST concern is that the supplier that we ordered the motors from is currently out of stick of those motors, and will not be able to fill an order for 4 more motors for another 4 weeks. We may have to buy different motors for the remaining two cars.
Changes to Design
- We are no longer using XInput library as unity allows for retrieving controller data without external libraries.
- Looking into the idea of using a PCB for the IR circuits and also provide more grounding pins to the motor driver.
Schedule Update
- We moved some task around so that we will have a more rounded product for the midpoint demo. Overall, we seem to be on track.
