2 x 75-minute lectures / week
This course explores the fundamentals of remote sensing techniques including
light detection and ranging (lidar), radar, and computer vision in the
context of emerging technologies such as autonomous navigation and terrain mapping. Throughout the semester, students are exposed to
a variety of sensors from the research and commercial domains - both in terms of hardware and software.

The course includes lectures from guest speakers of significant reputation in their respective branches of remote sensing. Guest lecturers join us from research, commercial, and government entities to discuss their work in remote sensing.
The course requires completion of a semester project employing the course material, CAD, rapid prototyping, and data collection & processing. The project provides students an opportunity to experience a hands-on project involving a remote sensing technology that is closely related to their area of study.

The lidar is integrated onto a standardized, 3D-printable mount. The mount consists of a single holder plate, which has mounting holes for an Arduino Uno, Raspberry Pi and Pi camera, and a LED line laser. The plate also has miscellaneous holes and slots allocated as cable tie downs, etc., along with two rectangular cutouts that can be used to tie the plate into a standard tripod.
A solid model file of the standardized plate is available for download. While it is
An additional 3D-printable piece is also available to attach the mount to a standard tripod via the two rectangular cutouts:
