-
Project Status: Ongoing M.Eng. project (Sep 2019 - Jan 2020)
-
Class: Advanced Topics in Product Design: Human Centered Design Development
-
Project Name: Designing Wearable Navigation Device for Visually Impaired
-
Project Scope:
- This is a human centered design project in association with Microsoft.
- Project aims at developing a technology that will guide the visually impaired people to navigate with better sense of surrounding.
- Our team is focusing on developing the wearable design that will satisfy the technological constraints as well as enhance the user experience. In the later stage of project, we will also fabricate the device.

Mobile Robot Skeleton
Current Sensing
Current Sensing Circuit Testing
-
Devised an electronic circuit to measure the current sensing in motor driver for variable load.
-
Performed Proof of Concept with breadboard testing.
-
Identified motor driver low-range current values and corresponding load values to perform calibration.
-
Built a working prototype and designed PCB.
Bed of Nails Tester
-
Developed basic CAD of Bed-of-Nail Tester with a box structure.
-
Based on user feedback, design had to be iterated for simplicity. Hence, came up with a structure to hold the PCB and in contact with Bed-of-Nail pogo-pin assembly.
-
Built a low-fidelity prototype for conceptualization.
-
Developed iterated CAD of Bed-of-Nail tester.
