Wrote and presented the Proposal Presentation to the class. We provided information such as our target user, user requirements, possible technical challenges, as well as proposed solution from a high-level. After the presentation, we got some good feedback regarding how the user will control the kart.
Investigated how FreeRTOS would be setup on the ESP32-S3 and STM32 microcontrollers, and made plans to implement them next week.
Investigated how BLE would be etup on the ESP32S3 and STM32WBx. Tested some starter code on Arduino IDE for ESP32 BLE services, downloaded/installed environments for STM32 firmware and debugging, and read through documentation and community forums for ST.
Began the Order List and will finish ironing it out by the end of next week.
Mostly completed component selection + schematic for both the glove and kar PCBs.
Design Changes
For hardware on the controller, instead of sticking with IMU sensors for inferring user command, we will also investigate flex sensors to detect motion on the user’s fingers. This will enable us to explore more controls that the user can do with their fingers, in addition to the tilt/rotation of the user’s hand.
Risks & Risk Management
One of the current risks that the team thought about this week is getting an accurate and reliable reading from the IMU. When creating the Order List, we will need to research extensively and explore a variety of IMUs online. To mitigate this concern/risk, we will order a few different types of IMUs and experiment to see which can provide the best measurements.
Another risk is that the PCB development is already behind schedule, but due to the team taking a moment to evaluate IMU and flex sensor options, this is to be expected; it is fully expected that the team will be back on track once this design decision is resolved.
