What are Cyber-Physical Systems or CPS?
- Is a CPS any engineered system with a microprocessor?
- Do all CPS need to be connected to the internet?
- Are there a set of basic functions and architectural elements common to all CPS?
You are invited to join us in answering these questions and charting the path to the future.

The overarching project goal is to advance the design of opportunistic state-triggered aperiodic controllers for networked cyber-physical systems. This poster considers the problem of opportunistic human-robot collaboration to solve multi-objective optimization problems. We consider scenarios where a human decision maker works with a robot in a supervisory manner in order to find the best Pareto solution to a given optimization problem. The human has a time-invariant function that represents the value she gives to the different outcomes.

The objective of this project has been to apply the techniques developed for communications networks to collaborative, intelligent vehicles. The techniques are applied to a lane merge protocol that assists a driver who is merging between two vehicles in an adjacent lane.
The previous work that has been reported on this project includes: a multiple stack, layered architecture; a strategy for using synchronized clocks; and the probabilistic verification of protocols.

Having a shared and accurate sense of time is critical to distributed Cyber-Physical Systems (CPS)
and the Internet of Things (IoT). Thanks to decades of research in clock technologies and
synchronization protocols, it is now possible to measure and synchronize time across distributed
systems with unprecedented accuracy. However, applications have not benefited to the same
extent due to limitations of the system services that help manage time, and hardware-OS and
