چکیده

<div class="section abstract"><div class="htmlview paragraph">The drilling of large quantities repetitive holes during the manufacture aerospace components is often considered a key limiting factor with regards to production efficiency. Whilst desire within use relatively cheap six axis robot arms end effector units, their poor accuracy remains an obstacle. Robot calibration presents way improving such that tolerances can be met, without permanently committing metrology equipment automation cell production. Extensive research has been conducted into by correcting kinematic model, known as parametric calibration. This method highly complex, and calibrates across entire working volume. not required in industrial applications, routines are contained smaller volume reach. In this paper, non-parametric proposed. involves calibrating regions where pose similar, thus effects geometric errors model roughly constant. By establishing average positional error for each region, locally improved compensation through definition tool centre point. The proposed completed models or complex mathematics, making it more suitable users. From experimental trials, significant improvement drilled using standard reported, from 2 mm 0.1 mm, well requirements majority applications.</div></div>

A Method to Improve Accuracy and Precision

Background and Purpose High-resolution ultrasonographic imaging is a nonnvasive method that allows estimation of the thickness of the intima-media complex in human carotid arteries. The determination of intima-media thickness involves several steps, each of which may introduce an error that influences the reproducibility of the method. In the present study, apart from the general reproducibilit...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Calibration of Robot Reference Frames for Enhanced Robot Positioning Accuracy

Industrial robot manipulators are important components of most automated manufacturing systems. Their design and applications rely on modeling, analyzing, and programming the robot tool-center-point (TCP) positions with the best accuracy. Industrial practice shows that creating accurate robot TCP positions for robot applications such as welding, material handling, and inspection is a critical t...
