Title of presentation: Humanoid Robot: A Review of Our Research Works

Abstract: Since 1996, we have embarked on the journey of developing humanoid robots at Nanyang Technological University, Singapore. We have ventured into the various technical aspects of humanoid robot development. In particular, we have placed special emphasis on mechatronics design of humanoid robots, planning and control of biped walking, hand-eye coordination for humanoid robots, cognitive vision for humanoid robots, and cognitive speech for humanoid robots. Since 2006, several teams in Singapore have received a substantial amount of research grants and have developed together two full prototypes of humanoid robots, which are about 1.8 meters in height and weigh about 80 kg each. And, each humanoid robot has 42 degrees of freedom with independent actuations. In this plenary talk, I will share some findings and results related to the R&D works of humanoid robot in Singapore.

Title of presentation: Artificial potential function methods in mobile robotics and multi-agent systems

Abstract: Motion control is the fundamental problem of mobile robotics. It is non-trivial even for typical non-holonomic mobile platform executing set-point control in a free space. Real-life applications require solving this problem in an environment with static or dynamic obstacles. The shape of obstacles affects the complexity of the algorithms significantly. Circular shaped obstacles are the simplest ones. Star-shaped class of obstacles includes ellipses, super-ellipses and more complex, convex and non-convex geometrical figures which, however, have 'center point' fulfilling the condition that all rays starting at this point intersect the boundary of the obstacle only once.
In this presentation an overview of selected algorithms based on artificial potential functions (APF) is presented. It includes both classic local APFs used to avoid collisions and global APFs, called navigation functions that not only avoid collisions but also drives the robot to the desired positions. Some of these approaches are extended to formations of robots that execute the task in a coordinated manner and avoid collisions between agents.
Usefulness of various developed control algorithms is determined by their properties: stability, convergence and their behavior in the transient states. Theoretical analysis of new control algorithms is presented. Simulation results supported by experiments with differentially driven mobile robots MTracker are widely discussed.

Title of presentation: Control Architectures for Robust Multi-Robot Autonomous Systems

The control of complex dynamic systems, both in their behaviour and in their mission, goes through the implementation of multi-loop control architectures based on information about the system internal state and from the environment, as well as on the mission plan state. This results in systems that are becoming increasingly autonomous, for which requirements in terms of safety and reliability, as well as expected performance, are increasingly high. Research works developed at ONERA in the field of control for autonomous systems cover all levels of the control architectures, which are basically structured with respect to temporal aspects, as well as the level of abstraction that they entail for the system dynamic.
We will consider them in presentation by increasing level. We will discuss the advances achieved recently in the robust control techniques of uncertain dynamic systems generally implemented at the lower control level and we will discuss their extensions to consider input and output constraints, as well as the hybrid nature of most of the systems considered. To design "task" level control primitives that take place just above the previous control loops, we will introduce sensor-based robust and non-linear control techniques. These are based on information on the environment extracted from exteroceptive sensors, to estimate their state and to adapt system behaviour to uncertainties and perturbations. Multi-sensor and/or multi-objective controls will be discussed in this particular context.

We will also present several recent results in the field of trajectory tracking based on visual navigation techniques in complex environments, which combine objectives and constraints within the same control architecture. We will discuss how model predictive control (MPC) techniques and advanced optimization techniques can be used for solving the resulting control problems. In addition, we will discuss several ongoing developments of these methods by exploiting distributed model predictive control techniques (DMPC) and predictive control of hybrid systems. Finally, integration with the control architectures at the upper level of reactive, predictive and distributed planning capabilities will be proposed to accommodate time constraints and uncertainties in decision.
