ME-202: Mechanical systems

Ce cours vise à approfondir la compréhension des lois de fonctionnement de plusieurs principes mécaniques majeurs et largement utilisés en construction de machines, en vue d'être capable d'en faire le dimensionnement dans les cas concrets les plus courants ...

Description

This lecture introduces the concept of collaborative robots, focusing on their fast execution speed and lack of contact or remote sensors. It covers the design of collaborative robotic arms, including their padded envelope bodies and assembly techniques. The lecture also delves into bolted assemblies, discussing self-locking mechanisms and the importance of thread contact transformation. Additionally, it explores prestressing in mechanical systems, explaining the internal closed-loop efforts and constitutive laws. Examples of prestressing applications, such as electric motor frets and coffee maker seals, are presented. The importance of load application factors and screw stiffness in mechanical systems is also discussed.

Mechanical engineering

Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, design, structural analysis, and electricity.

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.

Mechanical energy

In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes.

Industrial robot

An industrial robot is a robot system used for manufacturing. Industrial robots are automated, programmable and capable of movement on three or more axes. Typical applications of robots include welding, painting, assembly, disassembly, pick and place for printed circuit boards, packaging and labeling, palletizing, product inspection, and testing; all accomplished with high endurance, speed, and precision. They can assist in material handling.

Human–robot interaction

Human–robot interaction (HRI) is the study of interactions between humans and robots. Human–robot interaction is a multidisciplinary field with contributions from human–computer interaction, artificial intelligence, robotics, natural language processing, design, and psychology. A subfield known as physical human–robot interaction (pHRI) has tended to focus on device design to enable people to safely interact with robotic systems. Human–robot interaction has been a topic of both science fiction and academic speculation even before any robots existed.
