📢#IssueCover: Flexible Double-Sided Curvature Piezoresistive Sensor for Soft Robotics Cover Paper: https://brnw.ch/21wKI1e Authors: Racha Benarrait, Muneeb Ullah Khan, Jérémy Terrien, Hani AL HAJJAR, Frédéric Lamarque, Andreas Dietzel Technische Universität Braunschweig Université de Technologie de Compiègne (UTC) Full Volume 24, Issue 11: https://brnw.ch/21wKI1d Cover Story: #Soft #robotic grippers mimic the dexterity of human hands. To improve their performance, integrated sensors using flexible electronics enable real-time measurements, contributing to shape sensing, gesture recognition, and pressure mapping, allowing them to adjust their grip based on the object's shape. This paper shows the design, fabrication, and characterization of piezoresistive sensors arranged in a Wheatstone bridge configuration on a flexible polyimide substrate to detect curvature and bending. These sensors are embedded in PDMS with SMA foil (to mimic a human hand's finger movements controlled by temperature) and connected in a five-finger-shaped PCB, providing a voltage output while measuring the resulting finger shapes for future applications in soft robotics and prosthetics.

A rebar cage with protruding rebars on two sides makes it incredibly difficult for the nozzle to maneuver around. To tackle this, we leveraged an external axis (a turn-table) that can rotate the rebar cage during the spray process. This added degree of redundancy enhances flexibility but also complicates path planning. Traditional graph search methods in configuration space become inefficient as the degrees of redundancy increase. Instead, we utilized an adaptive multi-resolution graph to sample the configuration space (C-Space) only where collisions occur. This technique significantly speeds up the process. Using this advanced method, we produced an offline program in a short amount of time. The program ensures the nozzle maintains the correct orientation and avoids the rebar cage as it rotates on the palette. Watch the video to see this sophisticated obstacle avoidance in action and witness how our approach optimizes the robotic shotcreting process. #RoboticShotcreting #ObstacleAvoidance #PathPlanning #ExternalAxis #3DPrinting #ConstructionInnovation #AeditiveGmbH #StructuralEngineering #AdvancedAlgorithms #ConcreteTechnology #Robotic #Kuka #Algorithm #Rhino3d #Grasshopper3d #Automation #Precast #StructuralDesign #Building #Industry

✨ The Tripteron is a motion platform created by Laval University's robotics lab as a simple parallel actuator robot that is capable of multiple configurations, all of which are linear. In the orthogonal configuration, the actuation is also Cartesian. 💡 This platform is covered by a patent, which was filed in 2002. 🤖 A fixed build platform is simple and allows for consistency and high performance ✅ Parallel actuation avoids compounding of mechanical errors, if any exist. ✅ Framing and assembly are easy ✅ Part count is low 🔎 Tripteron can be used to build a 3D printer, as an example.

Adjust the deposition width during the print can simplify the deposition process while improving the quality of the results. We're excited to showcase a new application of #AdaOne's variable bead width feature, demonstrated on the MDAC10 cell in collaboration with Massive Dimension. This video highlights the "single wall" slicing mode, which allows for variable bead widths directly from a solid 3D model. The tool path automatically adapts to the model’s geometry, enabling intricate bead patterns with ease.

6D pose estimation of textureless shiny objects has become an essential problem in many robotic applications. Many pose estimators require high-quality depth data, often measured by structured light cameras. However, when objects have shiny surfaces (e.g., metal parts), these cameras fail to sense complete depths from a single viewpoint due to the specular reflection, resulting in a significant drop in the final pose accuracy. We are thrilled to share that our latest research has been accepted to #IROS2024! 🎉 In our paper, "Active Pose Refinement for Textureless Shiny Objects using the Structured Light Camera," co-authored by Yang J., Jian Yao, and Steven Lake Waslander, we present a complete active vision framework for 6D object pose refinement and next-best view prediction to mitigate the aforementioned issue. 🌟 Key Highlights 🌟: - Innovative 6D Pose Refinement: Our approach is tailored for SLI cameras and includes estimating pixel depth uncertainties and integrating these estimates into our SDF-based pose refinement module. - Surface Reflection Model: We predict depth uncertainties for unseen viewpoints using a reflection model that recovers object reflection parameters with a differentiable renderer. - Active Vision System: By integrating our reflection model and pose refinement approach, we can predict the next-best view (NBV) for pose estimation through online rendering.

Users in the steel or forging industries often encounter glowing round steel parts, such as the high-temperature round steel materials shown in today's video. These require robotic laser marking. The challenges are twofold. On the one hand, the high ambient temperature requires protection and cooling measures for both the robot and the 3D camera, and on the other hand, when steel is heated to a red-hot state, its properties change, posing challenges for visual recognition. We chose the AT-S1000-04A-S3, a high-precision, compact laser #3Dcamera, for our customers. ✅ This product excels at detecting and adapting to the glow characteristics of red-hot workpieces due to high temperatures. ✅ ALSONTECH's software can effectively analyse the point cloud collected by the camera, quickly extract the centre and contour of the round steel end, and guide the robot to achieve laser marking. ✅ This #3Dcamera uses a binocular structure, which provides good structural stability and effectively suppresses thermal drift caused by on-site temperature changes, ensuring stable performance in continuous high-temperature environments.
