Origami Robots

Ramses Martinez, Carina Fish, Xin Chen and George Whitesides have published a paper describing a soft pneumatic actuator constructed by combining paper with a silicone elastomer. On pneumatic inflation, these actuators move anisotropically, based on the motions accessible by their composite structures. They are inexpensive, simple to fabricate, light in weight, and easy to actuate. This class of structure is versatile: the same principles of design lead to actuators that respond to pressurization with a wide range of motions (bending, extension, contraction, twisting, and others). Paper, when used to introduce anisotropy into elastomers, can be readily folded into 3D structures following the principles of origami; these folded structures increase the stiffness and anisotropy of the elastomeric actuators, while being light in weight. These soft actuators can manipulate objects with moderate performance; for example, they can lift loads up to 120 times their weight. They can also be combined with other components, for example, electrical components, to increase their functionality.

uEye XC AUTOMATICALLY PERFECT IMAGES

Combining the ease of use of a webcam with the performance and reliability of an industrial camera? The uEye XC autofocus camera from IDS Imaging Development Systems proves that this is possible. Its high-resolution imaging, simple setup and adaptability make it an invaluable tool for improving quality control and streamlining workflows in industrial settings - especially for cases where users would normally employ a webcam. The uEye XC autofocus camera features a 13 MP onsemi sensor and supports two different protocols: USB3 Vision, which enables programmability and customization, and UVC (USB Video Class). The UVC functionality enables a single cable connection for easy setup and commissioning, while delivering high-resolution images and video. This makes the uEye XC camera an ideal option for applications that require quick setup and need to manage variable object distances. Additional features such as digital zoom, automatic white balance and color correction ensure precise detail capture, which is essential for quality control.
