The biggest risk we are facing right now is our parts not arriving on time. We are behind schedule if they do not come this week as our plan was to assemble the glove and begin testing. However, without hardware we are still making progress working on the communication between Raspberry Pi and software as well as working on the user-interface. This week we will finish the Design document and assemble the glove if our parts arrive. We will also continue implementing the software portions that we do not need hardware for.
This week we also formalized parts of the design for the design report, like picking which protocols we’ll use for MVP and final. The glove is based on Raspberry Pi and will use C for the controls. The IMU will use I2C to communicate with the Raspberry Pi. The flex resistors will communicate with the Raspberry Pi through its GPIO, possibly with capacitors to filter out noise. For MVP, the glove will communicate with the computer via USB, but we’d like to do wireless communication for final. We’re considering adjusting the weight requirements based on the batteries we’ve been able to find: if we can’t find a light enough battery to make the glove easy to use, we’ll need to switch to powering the glove with a USB cable or similar, but make the cable long so it’s still ergonomic.
