What I accomplished this week:
This week majority of my time was spent working on the design review report. Specifically, I worked on the following sections: Abstract, Related Works, as well as all the sections related to the shank-mounted wearable and the vibrotactile feedback throughout the report.
I met with Vu and Iqui this week with Kailtlyn to discuss 3 different methods for creating the soft case for the hardware components (outlined here). After this discussion, I decided that the best method for making the case is to 3D print a mold for the case (given the dimensions of the actuator system and the central component) and create the case using the mold and liquid silicone.
On schedule?
Yes, I am on schedule for prototype fabrication. We recently ordered a second round of parts specifically for the foot-mounted device as well as the soft case, and will begin prototyping different versions of the case after the team is back from spring break.
Objectives for next week:
- Fabrication of different models for the case mold. I aim to make 3 versions of the soft case
- Solder the new hardware components
- 2nd Seeed Studio MCU/IMU
- Integrate the on/off switch into the shank-mounted wearable
- Develop vibration command sequences for the left and right LRA and test to see which vibration pattern and waveform is the most detectable
