Skyrocketing growth in the cellular personal communications services (PCS) sector has fueled the needs for higher density, more functionality, and greater performance on both handset and basestations. Third generation wireless standards, which require hardware upgrades, loom on the horizon. RF component suppliers are scrambling to find solutions at the IC,(More)
This paper presents a pipeline inspection robot with a linkage mechanical clutch, which consists a novel belt driven ridged cone shaped skate model that can be used to conquest irregular environmental barriers. The mechanical clutch is a 3-bar linkage mechanism. The robot is designed to be conformal to the environment: each chain being in touch with the(More)
There has been a proliferation of real-time sensing application due to the recent technological improvements in small, inexpensive, low-power, and distributed “smart” sensor nodes capable of doing a small amount of data processing and storage. Sensor network coordinates a collection of these sensor nodes to enable a high quality detection(More)
In this paper, a new method of position along with node teaching and placement is proposed. Different from the traditional triangulation position, the proposed method employs a faster computation technique with special proximity learning and placement, which leads to reduced computational time. In position computation, the received signal strength(More)
This article presents an adjustable pipeline inspection robot with three belt driven mechanical modules. The adjustable pipeline robot can be used for 30–45cm diameter pipeline. This robot has three powered belt driven chains each of which has a mechanical clutch. The mechanical clutch is used a 3-bars linkage type mechanism. The robot is designed(More)
