Mori3 - Rolling loop Reconfigurable Robotics Lab - EPFL 2023-06-12 | The Mori3 is a robot capable of changing its own shape to adapt to new environments and unseen tasks. The Mori3 consists of autonomous pieces which can connect together to form large, complex, and moving systems.This video shows ten modules connected as a loop, rolling across the floor.Each module can change the length of each triangular edge. When all edges on a module are identical, the loop rolls in a straight line, like a cylinder. Extending all the edges on one side of the loop changes the system to resemble a cone, allowing the robot to steer around corners, without having to disconnect and reconnect modules.

Mori3: A polygon-based modular robot (all footage and descriptions) Reconfigurable Robotics Lab - EPFL 2023-06-12 | by Christoph Belke, Kevin Holdcroft, Alexander Sigrist, and Jamie Paik.The Mori3 is a modular robot built by the Reconfigurable Robotics Lab at EPFL.The Mori3 can change its own shape and function through changing the way modules interconnect.Each module is their own robot; they have their own power, motors, sensors. By themselves, they can drive around on the ground and change the length of each of their triangular edges. However, working together, they function as a complete system capable of achieving many different types of tasks. The Mori3 is geared towards difficult to reach environments where the task isn't always known ahead of time, such as space. For more please see the article linked below:Morphological flexibility in robotic systems through physical polygon meshing.doi: 10.1038/s42256-023-00676-8Abstract - Shape-changing robots adapt their own morphology to address a wider range of functions or environments than is possible with a fixed or rigid structure. Akin to biological organisms, the ability to significantly alter shape or configuration emerges from the underlying mechanical structure, materials, or control methods. Soft robots, for instance, employ malleable materials to adapt to their environment, modular robots assemble multiple units into various three-dimensional (3D) configurations, and insect-like swarm robots interact in large numbers to fulfil tasks. However, the promise of broad functional versatility in shape-changing robots has so far been constrained by the practical implications of either increasing the degree of morphological flexibility or addressing specific applications. Here we report a method for creating robotic systems that realises both sides of this trade-off through the introduction of physical polygon meshing. By abstracting functional 3D structures, collections of shape-changing robotic modules can recreate diverse 3D shapes and dynamically control the resulting morphology. We demonstrate this approach by developing a system of polygon robots that change their own shape, attach to each other, communicate, and reconfigure to form functional and articulated structures. Applying the system to three distinct application areas of robotics involving user-interaction, locomotion, and manipulation, our work demonstrates how physical polygon meshing provides a new framework for more versatile intelligent machines.

Foldaway - Ultra Portable Haptic Interface Reconfigurable Robotics Lab - EPFL 2017-08-30 | FOLDAWAY technology introduction.System description and possible applications. more information: www.foldaway-haptics.comcontact us: info@foldaway-haptics.comFoldaway Haptics Youtube Channel: youtube.com/channel/UCx4v3QiMSk67ZnWpgYiPH1Q?view_as=subscriberfollow us on facebook: https://www.facebook.com/foldawayhapt...In a world where machines and electronic devices are becoming ubiquitous and portable, the quest for low-cost and ultra-portable haptic interfaces is exponentially growing. However, the market is currently populated either by bulky and expensive interfaces that render forces with high accuracy, either by simple devices that exploit vibrations to render a limited number of sensations. FOLDAWAY, is innovating the field by developing ultra-portable and low cost origami haptic interfaces.The device has three degrees of freedom and can interact with human fingers by tracking their motion and providing force, stiffness and texture perception. Through its unique origami manufacturing, it is the first interface of its kind that folds-away when not in use. Its palm size, and thin design, makes it the ideal user interface for any portable device. The manufacturing of these structures is cost competitive, scalable and does not require manual assembly.
New soft robots really suck Reconfigurable Robotics Lab - EPFL 2017-08-30 | News Coverage EPFL Mediacom : Hillary SanctuaryEPFL scientists have created the first functional robot powered entirely by vacuum: made up of soft building blocks, it moves by having air sucked out of them. The robot can be reconfigured to perform different tasks, like climbing vertical walls and grabbing objects.This new robot sucks: to move, air has to be sucked out of its individual components. Inspired by muscle contraction, its individual soft components are activated (they collapse) when negative pressure (vacuum) is applied to them. The robot uses suction to grab objects or to stick to a smooth wall for climbing, so it can really achieve a wide range of tasks because of the unique properties of vacuum. The robot can be reconfigured to perform different tasks, making it highly modular and versatile, with a wide range of applications in both research and in industry. The invention is published today in Science Robotics.“What we have is a fully functional robot which is entirely powered by vacuum, which has never been done before,” says EPFL roboticist Matt Robertson who worked on the project. “Previous work has shown individual components powered by vacuum, but never in a complete system.”Vacuum-powered components are a recent addition to robotics – and, more importantly, they’re safe. Today, most actuators on the market are activated by applying positive pressure, i.e. by injecting air into their components. But containing positive pressure requires stiff high-pressure pneumatics, which also pose a safety threat: in extreme situations, they can explode. By comparison, vacuum-powered actuators are safe, soft, and simple to build.

SPA-Skin with PZT Sensors for Vibrotactile Feedback Reconfigurable Robotics Lab - EPFL 2016-07-15 | We present a soft pneumatic actuator (SPA)-based skin prototype that allows bidirectional tactile information transfer to facilitate simpler and responsive wearable interface. It is a 1.4 mm-thick vibratory SPA – skin that is integrated with piezoelectric sensors. Experimental findings show that this ultra-thin SPA and the unique integration process of the discrete lead zirconate titanate (PZT)-based piezoelectric sensors achieve high resolution of soft contact sensing as well as accurate control on vibrotactile feedback by closing the control loop. This system can not only detect the internal vibrations from actuators but also, external interaction forces as can be seen from the graph (inset).
4 gram origami robot (Robogami) that crawls and jumps Reconfigurable Robotics Lab - EPFL 2015-11-10 | Robotic Origami or Robogami is foldable quasi-2D crease patterned robots built from functional materials that can pop-up to reconstruct various 3D shapes and mechanisms, theoretically, with infinite degrees-of-freedom.Tribot is a unique mobile origami robot that can simultaneously choose between two modes of locomotion: jumping and crawling. When assembled, Tribot weighs 4 g, crawls at 17% of its body length per gait cycle and jumps seven times its height repeatedly. To optimize the practicality of the nominally 2D design, we made two different approaches to build the prototypes. For one of them, we used the "traditional", monolithic, layer-by-layer robogami fabrication method and the second, we printed out most parts using a multi-material 3D printer. The embedded sensors allow Tribot's crawling gait pattern and jumping height to be modulated with a closed loop control. For more details, please visit rrl.epfl.ch.
