Team Project for Applied Fabrication
I proposed to build Walkman as my final project for my applied fabrication class. Walkman copies the skills of animals such as bats, which emit sonar calls into their surroundings and use the echoes bouncing back from nearby objects to divert around them. Walkman sends out ultrasound waves and detects them on their return, and uses vibrations to inform users of any obstacles in their way.
Prototype 1 was the first test of concept. We used an Arduino Uno and attached a sonar sensor for sensing objects and a vibration motor for haptic feedback.
In our next version, we worked on fixing some technical issues we had in our first prototype. We scaled up our model to sense obstacles at a wider range and provide a diverse sense of haptic feedback.
In our final version we 3d print the molds, joints and safety boards. Mounted the device onto a elastic band with velcro straps.
Here's a look at our final product.
