Niveus is a remote controlled snowblower I designed in a group of 14
for MIT's Mechanical Engineering senior product design class, 2.009.
We took a commercial
CubCadet Snowblower, replaced the human pusher and handle with some
hefty screwdriver motors and a joystick controller. For remote
control we used a First Robotics controller board with a Basic
Stamp. It was quite satisfying to see it all work. If you are
interested check out our promotional video of
Niveus in action.
My contribution was primarily electronics: wiring up a 12V car
battery, GM alternator, additional motor controllers and safety
switches, as well as doing nifty things like wiring the controller to
a transistor to a relay to a solenoid to the starter motor to remotely
start the engine. In order to remotely determine if the engine was
running I used the preexisting handle-bar warming alternator as a
hall-effect sensor and wrote some code to alert the user when the
engine stalled and provided feedback that Niveus turned off when you
requested. We also alerted the user with a flashing light when Niveus
approached too close to a predefined boundary, like the edge of the
driveway. This feature was accomplished by hacking apart a
commercially available electric shock dog collar to detect proximity
to a buried wire.
