Abstract
This paper proposes a novel technique which provides energy efficient circuit design for sensors networks. The overall system presented requires a minimum number of independently communicating sensors and sub-circuits which enable it to reduce the power consumption by setting unused sensors to idle. This technique reduces hardware requirements, time and interconnection problems with a supervisory control. Our proposed algorithm, which hands over the controls to two software mangers for the sensing and moving subsystems can greatly improve the overall system performance. Based on the experimental results, we observed that our system, which is using sensing and moving managers, the four sensors required only 3.4 mW power consumption when a robot arm is moved a total distance of 17 cm. This system is designed for robot applications but could be implemented to many other human environments such as “ubiquitous cities”, “smart homes”, etc.
Highlights
All of the sophisticated and intelligent man made equipment need some sort of sensor to infer the environment
The controller of each sensor is capable of transmitting this data to the computer and to the counter so that it can be used by the overall system to guide the robot arm
Vector Matrix Multiplier (VMM) analog VLSI implementation function offers the potential of significant benefits in terms of power, volume, and performance compared to a digital implementation for applications involving fixed or slowly varying weights [10]
Summary
All of the sophisticated and intelligent man made equipment need some sort of sensor to infer the environment. Collecting these data from different sensors and to perform the required tasks in a minimum time requires the efficient use of minimum size and easy to install and use sensors, communications and power systems. The above features should be implemented in such a way that there is no loss of required data and redundancy other than the safety. This paper presents a sensing technique using an experimental platform for micro-sensors used in robot arm for various missions such as space and home networks. The use of several sensors in an array with multiple connections complicates the construction and movement, especially when changing the sensors
