Range finder sensors are widely used in the obstacle detection and collision avoidance applications. In this research, we propose rotating range sensor that provides economic efficient solution for mobile robot Rotating approach is achieved by coupling with servomotor. article, model design, main parameters, equations limitation described. addition, an algorithm developed to control rotation an...

Experiments were performed to measure the dependence of the delay time of the appearance of the first saccade preceding smooth eye movement on the velocity of the target. A clear hyperbolic dependence was found meaning that the delay time is composed of at least two components, i.e. the time needed to measure the stimulus velocity and the time to select one program for the smooth eye movement. ...

This paper proposes a vision-based fuzzy 8051 surveillance system which emphasizes on designing the image processing function to detect the invaded states and the 8051 fuzzy servomotors controller to track the invader region. The techniques include discrete wavelet transformation (DWT) image data reducing, edge detection, motion detection, and fuzzy servomotor control. In this paper, image proc...

A comparative study on performance in terms of transient time response specifications for position control of a separately excited DC Servomotor using Fuzzy logic control on PD strategy and general PD control strategy is done. Fuzzy Logic Controller (FLC) based on PD strategy is designed for both the inference mechanismsMamdani type and Takagi-Sugeno type. Robustness test for both the controlle...

The manufacture, maintenance and inspection of a ship involve series works on the shell plate, which were always seen as harmful for human operators time-consuming work. shipping industry is looking to replace manual work with automation equipment. A magnetic climbing robot that can omnidirectionally move plate was presented in this paper. This article summarized mechanical structure, control s...

Direct current (DC) servomotor-based parabolic antenna is automatically positioned using control technique to track satellite by maintaining the desired line of sight for quality transmission and reception electromagnetic wave signals in telecommunication broadcast applications. With several techniques proposed literature position control, there still a need improve tracking error robustness sy...

The goal of this laboratory activity is to design, implement and test a digital speed PI controller for the DC servomotor available in laboratory. Two different design approaches are considered: in the design by emulation, the digital controller is obtained by discretisation of a controller that is originally designed in the continuous–time domain; vice versa, in the direct digital design (or d...

Tactile displays are used to convey small-scale pressure and shape information to the finger tip. Our device designs include a 1x10 pin display using shape-memory alloy actuators and a 6x6 pin display using inexpensive commercially available servomotor-gearhead packages. Our human factors studies suggest that bandwidths of about 30 Hz are required for free exploratory motions with pin-based dis...

This work deals with parameter identification of permanent magnet motors, a class of ac motor which is particularly important in industrial automation due to characteristics like applications high performance, are very attractive for applications with limited space and reducing the need to eliminate because they have reduced size and volume and can operate in a wide speed range, without indepen...
