Electrohydraulic artificial muscles require high operating voltages, often several kilovolts. How can we reduce these voltages to avoid bulky and inefficient driving electronics? You can find out in our latest publication on low-voltage electrohydraulic actuators for untethered robotics. We introduce ferroelectrics in the actuator shell to reduce the required operating voltages significantly by 5 times. Due to the composite shell structure, these actuators are also safe to touch, are waterproof, and exhibit self-clearing properties.

https://lnkd.in/gqexWm9V Article Title: Vibration of flexible robots: Dynamics and novel synthesis of unbounded trajectories Author(s): Vibration of flexible robots: Dynamics and novel synthesis of unbounded trajectories Journal: Annals of Robotics and Automation Journal ISSN: 2994-418X Abstract: Flexible Robotic Systems, by and large, are prone to inherent vibration that recreates itself in several modal frequencies. This in-situ vibration in flexible robots or in any such complaint robotic unit becomes tricky so far as the control system architecture is concerned. Thus, customization of the design and firmware of higher-order flexible robots is highly challenging due to its inherent parameters related to real-time vibration. Vibration in flexible robots has been investigated hitherto from the standpoint of frequency & amplitude tuple, sidetracking the important paradigm of looping of the trajectories. This work has added a technological niche in bringing out the intrinsic dynamics of this vibration from a mathematical perspective of trajectory formation so as to understand the mechanics of spiraling loops while a flexible/compliant robotic system is vibrating under natural conditions. The analytical modeling of the said in-situ vibration has been experimented with through an indigenous single-link flexible robot, fitted with a miniature gripper. #Flexiblerobot #Compliance #Vibration #Modalfrequency #Nonlinearity #Engineering #MechanicalEngineering #ElectricalEngineering #CivilEngineering #ChemicalEngineering #ComputerEngineering #SoftwareEngineering #AerospaceEngineering #BiomedicalEngineering #EnvironmentalEngineering #StructuralEngineering #IndustrialEngineering #MaterialsEngineering #SystemsEngineering #Robotics #Peertechz #PeertechzPublications #Nanotechnology #RenewableEnergy #EngineeringDesign #EngineeringManagement #ManufacturingEngineering #AutomotiveEngineering #TelecommunicationsEngineering #Mechatronics #EngineeringMechanics #ControlSystems

Robotics is a field of engineering and science that involves the design, construction, operation, and use of robots. Robots are automated machines capable of carrying out tasks or activities autonomously or semi-autonomously. Robotics encompasses various disciplines, including mechanical engineering, electrical engineering, computer science, and artificial intelligence. The goal of robotics is to create machines that can assist or replace humans in performing repetitive, dangerous, or complex tasks efficiently and accurately. Applications of robotics range from industrial automation (e.g., manufacturing robots) to healthcare (e.g., surgical robots), exploration (e.g., space and underwater robots), and everyday life (e.g., household robots like vacuum cleaners). Advances in robotics continue to drive innovation and shape the future of automation and technology. #snsinstitution #snsdesignthinkers #snsdesignthinking

A miniature wireless robot that can effectively move through tubular structures. Robots have already proved to be promising tools to complete complex and demanding maintenance tasks. While engineers have developed a wide range of robots that could help to maintain and repair infrastructure, many of these robots need to be plugged into external power sources, which limits their real-world application. Researchers at the Max Planck Institute for Intelligent Systems, Harbin Institute of Technology, and Hong Kong University of Science and Technology recently developed a new wireless miniature robot that can move through pipes and other tubular structures without relying on external sources of power.

#snsinstitution #snsdesignthinkers #snsct Robot Operating System (ROS) has transformed the robotics industry by offering a flexible and powerful framework for building robotic systems. ROS is a middleware that enables seamless communication between the various components of a robot, including sensors, actuators, and controllers. The concept of nodes is one of the key features of ROS, which are individual computational units that perform specific tasks and communicate with each other through topics and messages. These messages can carry data such as sensor readings, motor commands, or even high-level commands for autonomous navigation. ROS's decentralized architecture facilitates modularity and scalability, allowing developers to easily integrate new hardware components or functionalities into their robotic systems. Additionally, ROS offers a rich set of tools for visualization, simulation, and debugging, making it an invaluable resource for both research and industry applications. If you are interested in the field of robotics, understanding ROS is essential. It is a game-changer in the industry and provides a foundation for building complex robotic systems.

IROS 2024, one of the most ambitious and prestigious conferences on Robotics. The following work from our team has been accepted for publication in the Proceedings of the 2024 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2024), which will be held in Abu Dhabi, UAE, from October 14 to 18, 2024. Minh Tuan Hua, Emil Mühlbradt Sveen, Siri Marte Schlanbusch, Filippo Sanfilippo. Robust-Adaptive Two-Loop Control for Robots with Mixed Rigid-Elastic Joints. Accepted for publication in the Proceedings of the 2024 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2024), Abu Dhabi, UAE, from October 14 to 18, 2024. In robotics, while rigid joints are common due to their accuracy and fast response ability, elastic joints are well-known for their safety when interacting with the environment. To harmonise the advantages of these joint types, robots with mixed rigid-elastic joints can be considered. In this paper, a robust-adaptive two-loop control algorithm is proposed to control this type of robot when there are uncertainties in system parameters. In the outer loop, a robust control algorithm is proposed to deal with the uncertainties in the dynamic parameters of the joint side, together with an adaptive controller for the rigid joints. In the inner loop, another robust control algorithm is proposed to handle the uncertainties in system parameters of the elastic joint’s motor side, and a similar adaptive control algorithm is presented to manipulate the elastic joints' motors. The stability of the system is assured by Lyapunov's stability theory. Finally, simulations are conducted to verify the proposed control algorithm.
