Machine Learning Driven Robot Motion Design and Implementation in a Web-based Mechanism Design Software

by Technical Committee for Linkages and Mechanical Controls

13:00-16:00 on 5th November 2023

Room: 42F Takao

Request for participants: Please bring your laptop.

This workshop will introduce attendees to a new computational framework which brings together machine learning with rigid body kinematics for simultaneous type and dimensional synthesis of mechanisms. Attendees will also be exposed to a new web-based mechanism design software, which implements research methods developed in the aforementioned framework. They will learn to use the software tool for designing and modeling planar N-bar, single- and multi-degree-of-freedom mechanisms and bring it back to their institutions for potential integration in their classrooms. The attendees will also engage in physical prototyping of their mechanisms using an in-house developed robot kit to take home. This work has been supported by several National Science Foundation grants.

Mechanisms for Sustainable Energy Systems

by Technical Committee for Sustainable Energy Systems

9:00-11:00 on 5th November 2023

Room: 42F Tama

Request for participants: None

Associate Professor PhD eng. Macedon Moldovan, Renewable Energy Systems and Recycling Research Centre, Faculty of Product Design and Environment, Transilvania University of Brasov, Romania

  1. Sustainable Development. The exponential growth of the world’s population in the last century has repeatedly raised questions about the ability of the Earth to provide enough resources to meet the needs of the present without compromising the ability of future generations to meet their own needs. The concept of Sustainable Development is discussed together with the Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development.
  2. Sustainable Energy. Sustainable Energy is a main part of the Sustainable Development. According to SDG 7, the access to clean and affordable energy is key to the development of all activity sectors. The three pillars of Sustainable Energy (energy saving, energy efficiency and renewable energy) are discussed.
  3. Mechanisms for solar tracking systems. One of the most accessible renewable energies is solar energy which can be converted into the two most used forms of energy today: electricity and thermal energy. The main aspects related to available and received solar energy are presented, focusing on the advantages brought by the solar tracking systems and on the existing mechanisms used in solar tracking systems.
