XR1922, XR1921, XR1911 XELA Robotics Tactile Sensor - Instruction Manual
■Applying too high forces or pressures will destroy the sensor module and will void the warranty. Never apply more than 3 N z-axis force (force applied perpendicular to the sensor's surface) to one sensor cell (the XR1922 has 4 sensor cells, for example). Regarding x-axis and y-axis, the sum of the shear forces has to stay below 15 kPa. These values are higher than the measurement range of the sensor (given in the datasheet), as the sensor can be overloaded.
▲Furthermore, apply forces only to the sensor surface, not to the sides of the sensor module.
■As a skin sensor, the contact geometry always influences the measurements. Therefore, we do not calibrate the sensors, as any calibration would be valid only for the same contact shape. We suggest that you use machine learning techniques or your algorithms to get various information out of the sensor measurements, relevant for your application.
■As our sensor uses magnetic field changes induced by the skin deformation as its sensing principle, other magnetic fields (including the earth magnetic field), nearby magnets, or nearby ferromagnetic materials can influence the sensor measurements. Also crosstalk between two of our sensor modules is possible. Please confirm within the inspection period (1 month from receipt of the product)with your application if those influences are prohibitory for your application. To counteract those influences, please also consider that a reference sensor could be used.
■Never bend the sensor modules. When you install the sensor modules on your robot, glue them to a sturdy and flat surface with thin double-sided sticky tape. Make sure to provide flat support to the whole backside of the sensor module.

How is the sensor constructed?
2024-07-30 - 技术问答 uSkin is a high-density, three dimensional, tactile sensor which consists of three main parts: The chip recognises displacement in three dimensions. Each sensor module includes a multitude of these chips, and each chip can measure 3D displacement individually. Soft elastomer ensures that the sensor is highly resilient to overloading, which makes uSkin very durable. Another feature that the soft skin adds to the sensor is the ability to conform to the object your robotic solution is trying to grasp. The outer shell serves the purpose of protection but can be modified for different applications. uSkin makes it possible to grasp objects with a human-like sense of touch, providing you with a precise, sensitive and overall more reliable grasping solution.
XELA Robotics Demonstrates Latest Tactile Sensors at ICRA 2024 in Yokohama

Is the software supplied with the sensor?
2024-08-30 - 技术问答 Yes, we currently provide the following software free of charge, please click here to review. The upcoming uSkin AI Software and the uSkin App will bring additional features such as slip detection, grasp success prediction, tactile object recognition, and many more to benefit the user. Our complete software solution will be available by the end of 2023 and operable with the uSkin App to improve the overall experience and ease of use. In particular, the following functions will be included in the software supplied with the sensor: -Grasping Features Grasping with Set Force/Pressure Grasp Success Recognition Slip Detection Re-grasping Suggestions for Unstable Grasps Self Learning -Tactile Object Recognition Detect Object Stiffness (upcoming) Detect Object Weight (upcoming) Detect Object Texture (upcoming) Detect Object Adhesion (upcoming) -Calibration Options XELA Robotics currently offers two options for calibration. Both calibration options will provide the user with more control over the grasped object and enable uSkin to measure forces in Newton, which will improve the reproducibility of the collected tactile data and enable the “set grasping force” feature. Standard Calibration (free) Individual Calibration (add on) For more information on our calibration options please click here.
