This paper present a type-2 fuzzy logic system can be applied to a mobile robot which is a project associates with using eight ultrasonic sensors as distance sensors. The inputs are obtained from ultrasonic sensors mounted. These inputs are sent to a microchip PIC 16F84 microcontroller onboard the robot, which analysis the data and provides the necessary control signal. The behavior based contr...

Though there are a variety of graphics tablets, these do not necessarily allow an artist to interact with the computer as if handling traditional pens and brushes. A study of practising artists indicates that haptic and propriaptic feedback respectively of pen pressure and motion, together with a direct view of the image being created, is required. Flat-screen LCD (Liquid Crystal Display) techn...

The deployment of a wireless sensor network to monitor subjects’ locations and relative distances during psychological experiments is discussed. As its primary function, an overhead array of ultrasound sensors automatically tracks a parent, child and stranger over a 4.45 m×4.23 m observation area. The array of ultrasonic-equipped motes can resolve two point targets separated by at least 73 cm. ...

Variable rate spraying technology can improve the pesticide utilization ratio, reduce the waste of pesticide, and canopy volume was a very important variable rate reference in orchard spraying, so a variable rate spraying system based on canopy volume measurement was presented and developed. The system was mainly made up of PC, ultrasonic sensor, single chip, flow control mechanism and nozzles....

A signal processing method was developed to improve the resolution and accuracy of ultrasonic Doppler ground speed sensors particularly in low speed ranges. Prototype sensors were made and tested. The sensor consists of ultrasonic transducers of 200 kHz and electronic circuits for signal processing. The frequency of received signal from the ground was multiplied by 5 to increase the resolution ...

Map Building and Position Estimation are basic tasks in mobile robot navigation with path planning. A method to generate a global map of the vehicle work environment using ultrasonic sensors is developed in this paper. Depending on the physical properties of the walls that form the room where the robot is navigating, sonar sensors show different behaviours. A neural network is utilized to inter...
