|Speech : Probabilistic Techniques for Mobile Robot Navigation
Probabilistic approaches have been discovered as one of the most powerful approaches to highly relevant problems in mobile robotics including perception and robot state estimation. Major challenges in the context of probabilistic algorithms for mobile robot navigation lie in the questions of how to deal with highly complex state estimation problems and how to control the robot so that it efficiently carries out its task.
In this talk, I will present recently developed techniques for efficiently learning a map of an unknown environment with a mobile robot. I will also describe how this state estimation problem can be solved more effectively by actively controlling the robot. For all algorithms I will present experimental results that have been obtained with mobile robots in real-world environments including autonomous cars, logistics applications, and robots navigating in city environments.

He completed his M. Tech from IIT Kharagpur and Ph. D from McGill University, Canada. Upon completion of his Ph. D, he joined Toshiba Corporation’s R&D Center in Japan. After 4-years of work experience in Japan, he returned to India in 1995.
He is actively engaged in teaching, research, and technology development. Prof. Saha recently completed the design and installation of an electrically-driven Six-DOF motion platform for an industry in India.

As recognition of his international contributions, Prof. Saha was awarded Humboldt Fellowship in 1999 by the AvH Foundation, Germany, and the Naren Gupta Chair Professorship at IIT Delhi in 2010. He has published a text book on “Introduction to Robotics” published by McGraw-Hill which is supported with a popular software RoboAnalyzer which he distributes free. He has also co-authored Dynamics of Tree-type Robotic Systems published by Springer in 2014.
|Speech : Two Decades of DeNOC-based Modelling and Its Use in Robotics
The decoupled form of the Natural Orthogonal Complement (NOC) of the velocity constraint matrix of a mechanical system used in dynamic modeling is referred here as DeNOC. It has been proposed by the speaker first in 1995 during IEEE Conference on Robotics and Automation held in Nagoya, Japan. Initially, the concept was used for the development of recursive inverse and forward dynamics algorithms for serial-type mechanical systems, e.g., the industrial manipulators. Later, the methodology was extended to several systems with different topologies like parallel Stewart platform, serial flexible systems, and tree-type and closed-loop systems. A general-purpose software called Recursive Dynamic Simulator (ReDySIM) written in MATLAB, which is freely downloadable http://www.redysim.co.nr/. However, the original serial-chain algorithms were used in the educational software named RoboAnalyzer, also available free fromwww.roboanalyzer.com. Some of the advantages of the DeNOC-based formulation are:
1. Analytical expressions of the terms appearing in the equations of motion, e.g., the Generalized Inertia Matrix (GIM).
2. Physical interpretations of the above expressions, e.g., mass matrix of a composite- or articulated-body.
3. Analytical decomposition of the GIM resulting into recursive, efficient, and numerically stable algorithms.
4. With the introduction of ‘determinate’ and ‘indeterminate’ subsystems in a closed-loop system, generation of a very efficient inverse dynamics algorithm, etc.
The talk will revolve around how to formulate the dynamic equations of motion using the DeNOC, and its applications in several robotic systems like industrial robots, biped, quadruped, etc.

|Speech : Rehabilitation Robotics: A Design Perspective
Robotics is emerging as a viable solution to numerous medical applications. It can improve the quality and efficiency of healthcare system, reduce trauma in surgery, assist patients in walking, or provide automation in medical research laboratories. Areas such as surgery, rehabilitation, independently living, and radiotherapy, are among the areas that widely use robotic systems. The recent advancement in underlying mechatronics technologies, including computers, sensors, actuators, or intelligent control, have increased the capability of robots in executing complex tasks, thus improving their chance of adoption by medical community. Nevertheless, designing robots is a complex multidisciplinary iterative process, where designers are required to have skills and communicate their designs in various disciplines, and work in a collaborative environment to bring innovative projects to completion. This talk, starts by a quick overview of robotic system evolution and multidisciplinary design process, with special emphasis given to biomedical robotics. The speaker will follow by discussing the current research in rehabilitation robotics at Carleton University’s Advanced Biomechatronics and Locomotion laboratory (ABL). The presenter’s research spans from aerospace robotics to stroke rehabilitation, early mobilization, and assistive devices. Major issues such as stability of interactive controllers, sensing, safety, and learning controllers, will be highlighted.
