At Robotics, Intelligent Systems, and Control (RISC) Lab, we design and build a team of underwater robots that can autonomously navigate and perform manipulation tasks in subsea environments. Applications of the underwater robotic systems include underwater environmental monitoring/preservation and data/sample collection among others. However, there are many technical challenges to make them fully autonomous in underwater environments where human intervention is extremely difficult. For instance, the operation and safety of the robots could be affected by communication losses, multi-path effects, ocean current, distorted vision, etc. In this microelectronics winter camp project, we design a robust embedded control system based on Fractional-order (FO) controllers, which are known to outperform their integer-order counterparts. The tasks of participating student(s) are (i) designing and implementing FO controllers for motion, speed, and depth control and (ii) integrating and testing the FO control system in one of our underwater robots in RISC Lab.
