Fault tolerance is increasingly important in industrial robots. The ability to detect and tolerate failures allows robots to effectively cope with internal failures and continue performing designated tasks without the need for immediate human intervention. To tolerate hardware failures, a set of fault tolerance algorithms are written for each component. These processes are responsible for detecting faults in their respective component and minimising the impact of the failure on the robot's performance. This work presents new intelligent neuro-fuzzy fault detection algorithms, which detect failures in robot components using analytical redundancy relations. An intelligent fault tolerance framework is proposed in which a fault component database or rule base and the detection algorithms work together to detect and tolerate sensor or motor failures in a robot system. Motor faults as well as sensor faults are considered. The Scorbot ER 5u plus model was simulated in robotics toolbox for MATLAB using the neuro-fuzzy algorithms.

New California Regulations Pose Challenges and Potential Economic Benefits for Industrial Facilities
States like California are well on their way to implementing laws, rules, and regulations that call for more community ambient air quality monitoring and greater transparency from the chemical industry. For instance, California Assembly Bill 617, signed into law this July, establishes a statewide air monitoring network and calls for greater community air quality monitoring in and around chemical facilities. At the same time Assembly Bill 1647, signed into law earlier this month, directs local air pollution...
The recipe for the successful sales of environmental sensors
“One accurate measurement is worth a thousand expert opinions”. This quote from Grace Hopper, the famous American computer scientist, provides a good insight of my passion for the measurement industry. There’s no wonder why I decided to meet the challenge of working at Lufft again: The company, which I already worked for from 2008 until 2012, gave me a real taste for this business. In this increasingly interconnected world, sensors are in use at the most critical point of the information...
Light Color Recommendations for Commercial and Industrial Spaces
Commercial, recreational and industrial spaces, such as offices, construction sites and outdoor parking lots, have different lighting needs. In most cases, the activities conducted on the location dictates the type of luminaries used, brightness settings and colors of the lights. Light color is a salient aspect of lighting systems, due to its passive contributions to productivity and clarity. Such components are measured using a Kelvin color temperature scale, with 1,500K-2,700K ratings resembling warm, yellowish...
The benefits of a Force-Balanced Sensor
Your project needs the precision to monitor movement as fine as 1 µG or µradian, but there will also be a lot surrounding noise and vibration that you don’t want to interfere with your readings. If you’re working on something like this, a sensor with force-balanced technology is the answer and here is why. Benefits of Force-Balanced Sensors Force-balanced sensors have a strong dynamic response (as much at 200 Hz for some models) and diverse measuring ranges, up to +/-90° for...
IIoT Sensors and Industry Use Cases
The term “Internet of Things”, or IoT, has been making waves in the industrial, commercial, manufacturing and consumer markets over the past years since the concept was formerly introduced in 2012 by the The Global Standards Initiative on Internet of Things (IoT-GSI). Coined as a term for computing devices that can perceive the world without relying on humans for data input, the Internet of Things (IoT) concept promises a world of seamlessly interconnected devices communicating together to process new...
