Title: 2022 - Using GPS to Implement PID Control for a Remote-Control Car’s Speed - Oral Presentation
Description: ENGR 2900 students work on improving the SLICK Science cars that are used for an interactive summer camp for middle school students to learn more about engineering and robotics. This year, students plan to add a PID controller to the throttle so that the cars can maintain a desired speed regardless of the surface on which they are driving. PID controllers are a common way of aligning as closely as possible the output of a system to a desired value. The “P”, “I” and “D” in PID control stands for “proportional”, “integral” and “derivative”. Implementation of a PID control comes in comparing the output of a system (as read from a sensor) to a desired input. The difference between the two, the “error”, is then integrated and differentiated and the new output to the system is a scaled up or down version of the sum of the proportional, integral, and derivative terms. With the implementation of PID control, the motors on the SLICK Science cars will work harder to maintain a certain speed on rough terrain, such as grass, than they will on smooth surfaces like asphalt. The controller uses information from the GPS in a closed loop system in order to adjust power to the motors. PID controllers are a powerful way of controlling an input given a desired output and are used in many every day and industrial applications. This is a video of the presentation, "Using GPS to Implement PID Control for a Remote-Control Car’s Speed" given at the 2022 Undergraduate Projects & Research Conference at Salt Lake Community College. The presenter: Cecilia Costelow, Jacob Sampson, Jeremy Riedl & Quentin McRae. The video can be accessed via YouTube here: https://youtu.be/lEYzN-oAvsA

Title: 2022 - Overview of the Mars Rover - Poster Presentation
Description: The Bruin Robotics Club will be presenting the Mars Rover at the 2022 UPRC. The Rover is comprised of different components that contribute to the mechanical design and overall communication system. The mechanical design has generally focused on converting the 3D printed prototype models to aluminum parts. Outside of the mechanical design of the platform, components on the rover includes LiDAR which helps with obstacle detection, a rocker bogy suspension that allows the rover to traverse over various types of terrain, the power system that provides power to the motors as well as to all of the sensors on the rover, electronic speed controller which will set the speed that the rover should be moving at, autonomous navigation that uses a GPS sensor to calculate current and desired location. The overall communication system design determines how all of the different sensors talk to the micro-controller. At the conference, we will be discussing the above topics in more detail via a poster presentation.

Title: 2022 - Demonstration of Work and Energy Using a Stirling Engine - Poster Presentation
Description: We designed an experiment to demonstrate the concepts of heat and work in a thermodynamic system. Heat is thermal energy in the form of the movement of particles at the molecular and atomic scale. A Stirling engine is a mechanical device that can harness heat energy into the mechanical energy of a spinning flywheel. In this lab experiment, the efficiency of the Stirling engine is determined by calculating how much heat energy in the system is transferred into the actual rotation of the flywheel of the engine. Through doing this, it demonstrates, in a non-abstract way, the concepts of work and energy.
