Risks and Contingencies
- The CMU wifi networks may not give connected devices public ip addresses, which could force us to change our network architecture to meet latency requirements. We’re looking into it more this week. In the worst case we’ll route communications through a server with a public ip address.
- Unsure if the motors we chose will have enough torque/rpm to be able to move the car freely. Have asked to meet with Sam later this week to discuss basic car mechanics and develop a good way to evaluate what motors we purchase for our cars.
- We are not sure if we have the budget to buy all the parts we need because we’re still shopping around for parts. When we do purchase parts, we’ll buy enough parts for two cars instead of the three we wanted in case we need to change parts. We’re also planning to implement the IR component later since we can compensate for a lack of those sensors with software.
Changes to Design
- We decided not to order custom PCBs, but rather to order prototyping PCBs and through-hole solder our circuit components. This change was necessary as it saves us much of our budget (~ $80+) that we can allocate elsewhere. While we save money, this does involve more manual labor when we actually have to build the IR circuit. We will mitigate this time cost by sharing the labor when this task occurs (rather than have one person solder, all three of us can).
Schedule Update
