MICRO-451: Applied and industrial robotics

This course is a real contact with industrial robotic applications. Components and mechanisms are reminded. The fields of microtechnical assembly and packaging are treated. CTOs from established companies (BlueBotics, Adept, Maxon motors and UniTechnologie ...

Description

This lecture covers the simulation and modeling of dynamic responses using Simulink, focusing on acceleration profiles, natural frequencies, and rigidity calculations for multi-axes robots. It also discusses the modification of rigid body models to consider eigen-modes and anti-resonance solutions.

Instructor

Mohamed Bouri

Dr. Mohamed Bouri is a group leader of Rehabilitation and Assistive Robotics in LSRO and lecturer of Robotics and Industrial Robotics. He graduated in Electrical Engineering in 1992 and obtained his PhD degree in 1997 in Industrial Automation at INSA LYON, France. Since 1997, he is at EPFL and is mainly active in the field of robot control, automation and robot design for medical and industrial applications. He is the head of Rehabilitation and Assistive Robotics group since 2005 and has strong references with the development of robotic devices for lower limb rehabilitation : The MotionMaker and WalkTrainer commercialzed by the company Swortec. His ongoing research currently focuses on the development of exoskeletons and the associated control strategies. His main current projects are TWIICE, a lower limb exoskeleton for people with paraplegia, AUTONOMYO, a walk assistance exoskeleton for people with muscle weakness, and the HiBSO, a hip orthosis for elderly.

Robotics

Robotics is an interdisciplinary branch of electronics and communication, computer science and engineering. Robotics involves the design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics engineering, electronics, biomedical engineering, computer engineering, control systems engineering, software engineering, mathematics, etc.

Robot

A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics.

Robotic arm

A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand.

Computer simulation

Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering.

Simulation video game

Simulation video games are a diverse super-category of video games, generally designed to closely simulate real world activities. A simulation game attempts to copy various activities from real life in the form of a game for various purposes such as training, analysis, prediction, or entertainment. Usually there are no strictly defined goals in the game, and the player is allowed to control a character or environment freely. Well-known examples are war games, business games, and role play simulation.
