The nature has a beautiful source of inspiration for reaching invisibility. Jellyfish are well-known sea creatures that are transparent and look transparent so that they are almost invisible in seawater. Consider flat fishes such as winter flounders that hide themselves from predators by adapting their skin pigments according to the background environment, cells, located in the dermis and epidermis...
Large contact area, zero scrub, three-degree-of-freedom holonomic vehicles (ldquoLCArdquo ldquoZS-3rdquo vehicles) are proposed for use in mobile robotics applications. ZS-3 vehicles avoid any rotational degree of freedom about a surface-normal axis between respective paired vehicle-ground contacting surfaces, resulting in nominally zero scrub at the surface contact plane. We briefly survey various...
This paper describes the vision-based obstacle detection system of the CWRU Cutter, an Autonomous Lawnmower developed for the annual ??Institute of Navigation (ION) Autonomous Lawnmower Competition.?? Unlike LIDAR sensors commonly found on autonomous vehicles, computer vision systems can provide similar information at drastically reduced prices. Though significantly more cost-effective than LIDAR,...
