Ka C. Cheok, Ph.D.
He received the B.S. Electrical Engineering from the University of Malaya in 1977, and the M.S. Electrical & Computer Engineering & Ph.D. Systems Engineering from Oakland University in 1979 and 1982, respectively. Ka C Cheok joined OU as an assistant professor in 1984. He is currently a full professor of engineering at the Electrical and Computer Engineering Department.
Dr. Cheok is active in the research areas of computer-based automated systems involving artificial intelligence and computer visualization. His contributions include the development of heuristics search, fuzzy logic and neural network techniques for guidance of autonomous robotic vehicles, and control of active suspension, automotive traction and tracking systems for the automotive and defense industries. He has published over nine patents, 40 technical journal articles and 100 conference papers.
He is currently working with a local startup company to develop automated breast cancer detection tester that combines robotics, computer vision, IR thermography and AI decision to automatically diagnose patients. He is also assisting with a colleague in the University of Pristina on a mine detection robot that sweeps for anti-personnel ordinance.
In the past few years, he had helped another company to incorporate fuzzy logic algorithm into a computer vision for recognizing and steering an autopilot automobile smoothly through various road topologies on a highway and city street lane centering system. He was also involved UWB tracking of mobile robots and assets in GPS-denied areas and path planning of omnidirectional robotic vehicles, where the flexible and agile operation leads to savings in cost, time and efforts.
He is co-chairman and co-founder of the annual Intelligent Ground Vehicle Competition (IGVC) co-organized and hosted by Oakland University. He is the faculty advisor for the Oakland Robotics Association, whose team took the top prizes at the 21st annual IGVC in June, 2013, among 53 collegiate teams from across the globe.

Education Plan and ProgramOU has already established the following education program to promote Smart Vehicle Systems through Intelligent Ground Vehicle Competition (IGVC). OU, US Army TACOM, the SAE and AUVSI organize and host the annual international IGVC since 1993. Each year engineering students teams (approximately 200 plus students; roughly 80% undergraduates and 20% graduates) from 20 to 30 universities (OU included) from the US, Canada and Japan build autonomous Unmanned Ground Vehicles (UGV’s) that compete in the IGVC events. The UGV’s must autonomously navigate around obstacle courses in the quickest and safest manner. The challenge requires integration of multidisciplinary technologies (computer, camera, GPS, radar, sonar, electronics, motors, drive train) with smart system decision (signal processing, estimation, control and navigation). The IGVC is sponsored by government agencies, automotive, robotic and defense industries (see www.igvc.com). The SVS Center will promote additional events in the IGVC.

Its application can be extended to areas of security surveillance, field harvest, etc. Self-Guided Systems has committed to bringing this concept into the commercial and consumer market place and will support OU for the next several years.|
|Collision Warning and Avoidance (CWA) systems. Automobile safety systems are being researched extensively by automobile manufacturers and their first-tier suppliers. In 1999-2000, OU demonstrated a CWA system for a military hummer to the National AutomotiveCenter at the US Army TACOM facility in Warren, Michigan. With the CWA system, the vehicle would warn its driver and automatically slow down when its sensor integration (radar, sonar and camera) algorithm perceived a potential impending collision. The project led to support from the Army, Ford and Hitachi. It is envisioned that this automotive research will lead to smart systems that will save lives or minimize collisions.|
|Short-range radars. OU is also working with a radar manufacturer called M/A COM, and Ford Scientific Research Lab, concerning embedded functions for processing the millimeter wave radar. OU is developing neuro-fuzzy logic clustering and tracking technique for short-range radar arrays to monitor traffic in front of the automobile. The project will be sponsored through 2003. Commercialization of the systems is currently being pursued.|
|Virtual Vehicle System Simulation (VVSS). OU has developed a 16 degree-of-freedom full vehicle driving simulation environment for the purpose of virtual prototyping and engineering performance evaluation studies of vehicle subsystems. The simulation environment is employed for various projects and collaborations. The VVSS has been used to design and benchmark a robotic convoying system in a leader-following configuration for US-Army TACOM. It has been used by the Automotive Research Center (ARC) to simulate and evaluate a rollover warning and avoidance system for SUV’s. It is currently being used to evaluate multi-radar collision warning and avoidance schemes for automotive safety application. The VVSS consists of an open architecture mathematical representation of a vehicle system. The architecture allows for Pentium-PC workstation on the local area network, to interact with the simulation execution in real-time, using the Matlab/Simulink environment. The simulation incorporates Human-in-the-Loop and Hardware-in-the-Loop capabilities as well as a motion base simulator for force-feedback studies.|
