The York University Rover Team
I joined the York University Rover Team (YURT) in 2009. It was a team of undergrads with a goal to build mobile robots ("rovers") that compete in the annual University Rover Challenge (URC) in Utah and the NASA Lunabotics Mining Competition in Florida.
My major contribution was the electronics and embedded software for three generations of rovers: PCB design and fabrication, design and implementation of communication protocols for control, integration tests, wire management etc.

Besides the epic road trips to the Utah desert and the Kennedy Space Center in Florida (yes we drove there from Toronto, Canada), I also get to play with lots of cool toys, such as servo pan-tilt-roll units, mesh-capable RF modules, all kinds of sensors, optical rotary encoders, and single-board computers.
My primary work for the 2012 rover was the communication framework. The work is detailed here.

Software Architecture and Other
Software Architecture and Other
The rover control system consists of multiple computers and microcontrollers over regular TCP/IP and XBee networks. Various programming languages were used to implement the software: the user interface was written in Python and C#; the communication framework in C++; simulation and automated testing in MATLAB; microcontrollers programming in C.
