Project Description
Coursework for ES96, Junior Design Tutorial. In light of the record snowstorm that shut Boston down for a week in 2015, Harvard University professors and Facilities Maintenance Operations reached out to us for new snow removal solutions.
Advisor: Prof. David Mooney
Project Details
Our team of 18 students developed three new snow removal methods: a snow-melting hydrogel-based mat, a nichrome icicle cutter, and a robotic snowblower (my team's focus). I was one of the primary drive train designers.
-
Weighs < 400 lbs, breaks into 2 pieces such that it can be carried by hand.
-
Drivable using a Playstation controller over the Harvard Wifi
-
Small enough to work on flat rooftops: turning around corners without damage, reducing risk of human injury if a structure buckles under snow's weight

Components
Teammate Cesar Maeda talks about the various specifications of our snowblower.

Gear Box Design
One of my key contributions. The motors and gears needed to be able to fit inside the pre-existing framework and align with the already existing openings for axles.
Demo: Wheels in Action
Demonstration of the functionality of the gear box components, driven wirelessly from a computer on the other side of the room.
