確保自主汽車射頻鏈路失效時的安全

　　主要公司的口袋里正在積極追求自主車輛和機器，但在平衡的生命和法律責任，設計師的壓力下，以確保導航性能最佳。這意味著傳感器備份和冗余。

　　本文介紹了無線導航如GPS和Wi-Fi的情況下，可以呈現無法操作。然后，它勾勒出一個設計和實施方法，使用替代和互補的輔助工具和傳感器的自主車輛和機器人。特別是，它將指向選項，幫助補償的位置和狀態的RF連接的變幻莫測。

　　Tech adoption’s un-sensed side effects

　　From delivery services for products and pizza， to Johnny Cabs from ‘Total Recall”， both car makers， retailers， and service corporations （like Uber） are putting a lot of resources into robots and vehicles that are location aware and adaptive to their immediate environments.

　　Meantime， the federal government has given the green light for states to regulate autonomous vehicles， and we are living in an evolving time with this new technology just beginning to be integrated into the transportation networks. As design engineers， we need to make sure this is done safely， especially given how lives and liability are in play.

　　While navigational aids like GPS have become almost indispensible， it seems that the more we rely on technology， the less able we are to perform even the mundane tasks that our devices perform. It’s getting to the point where people rely on GPS to navigate places they traverse on a daily basis. This can be troubling， especially as we realize that our technologies can fail. And when they do， we risk helplessness; or worse.

　　For example， as GPS systems strive to achieve finer resolution to ensure accuracy and reliability， there will be times when loss of signals could lead to catastrophic effects without some form of system backup. Anyone using a GPS knows what happens to a GPS signal upon entering a long tunnel.
