Program Description

Pathfinder's Electronics/Robotics Technology Program is based on the exposure, comprehension, and application of engineering and technical principles fundamental to electronics technology in industry. Students are provided the opportunity and motivation to prepare for entry level employment and post-secondary education in the dynamic and challenging field of Electronics. Students will develop both theoretical and practical skills through a planned sequence of topics. Students work in a contemporary technical shop area/lab facility complete with powered work benches, computer work stations, and state-of-the art testing and measuring equipment.

In addition, students receive instruction in robotic principles, including, but not limited to the conceptualizing and application of gears, sensors, and programmable controllers. VEX robotic components are utilized to not only learn and apply these skills in the shop area, but students will also have the opportunity to join our extra-curricular robotics club. The club is comprised of multiple teams that design, build, and program a robot to enter and compete in local and regional VEX competitions.
