In this article we will discuss the development and implementation of a computer vision system to be used in decision-making and control of an electro-hydraulic mechanism in order to guarantee correct functioning and efficiency during the logistics project. To achieve this, we have brought together a team of engineering students with knowledge in the area of Artificial Intelligence, Front End and mechanical, electrical and hydraulic devices. The project consists of installing a system on a forklift that moves packaged household appliances that can identify and differentiate the different types of products moved in factories and distribution centers. Therefore, the objective will be to process this identification and control an electro-hydraulic pressure control valve (normally controlled in PWM) so that it releases only the hydraulic pressure configured for each type of packaging/product, and thus correctly squeezing (compressing) the specific volume, without damaging it due to

iMotions employs neuroscience and AI-powered analysis tools to enhance the tracking, assessment and design of human-machine interfaces inside vehicles. The advancement of vehicles with enhanced safety and infotainment features has made evaluating human-machine interfaces (HMI) in modern commercial and industrial vehicles crucial. Drivers face a steep learning curve due to the complexities of these new technologies. Additionally, the interaction with advanced driver-assistance systems (ADAS) increases concerns about cognitive impact and driver distraction in both passenger and commercial vehicles. As vehicles incorporate more automation, many clients are turning to biosensor technology to monitor drivers' attention and the effects of various systems and interfaces. Utilizing neuroscientific principles and AI, data from eye-tracking, facial expressions and heart rate are informing more effective system and interface design strategies. This approach ensures that automation advancements
Electrification isn't just a matter of switching out the diesel engine for an electric motor. It requires a thorough review of connected systems - particularly the hydraulic system. Using the same components in electric machines as those used in conventional machines often requires more battery power or a larger electric motor. For this reason, OEMs have discovered the need to rethink efficiency and productivity when electrifying machines. MPG Makine Prodüksiyon Grubu learned this firsthand when designing a truck-mounted electric crane for one of its Netherlands-based customers. The Konya, Turkey-based OEM produces truck-mounted hydraulic cranes with folding and telescopic booms as well as aerial work platforms and tree trans-planter machines.
Heavy vehicles such as construction machinery generally require a large traction force. For this reason, axle components are equipped with a final reduction gear to provide a structure that can generate a large traction force. Basic analysis of vertical load, horizontal load (traction force), centrifugal force, and torsional torque applied to the wheels of heavy vehicles such as construction machinery and industrial vehicles, as well as actual working load analysis during actual operations, were conducted and compiled into a load analysis diagram. The loosening tendency of wheel bolts and nuts that fasten the wheel under actual working load was measured, and the loosening analysis method was presented. The causes of wheel fall-off accidents in heavy trucks, which have recently become a problem, were examined. Wheel bolts are generally tightened by the calibrated wrench method using a torque wrench. The method is susceptible to variations in friction coefficient and tightening torque
Engineers at the University of California San Diego have developed electronic “stickers” that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces. That makes them versatile for a wide range of applications, from arming robots with a sense of touch to elevating the immersive experience of VR and AR, making biomedical devices smarter, monitoring the safety of industrial equipment, and improving the accuracy and efficiency of inventory management in warehouses.
NMC and LFP lithium-ion batteries find favor in different regions as OEMs move to electrify larger excavators and loaders. The success of electric vehicles in the construction industry will largely be determined by battery prices being low enough that the total cost of ownership is cheaper than diesel alternatives. IDTechEx's new report, “Electric Vehicles in Construction 2023-2043,” shows that there is a battery price tipping point, under which it will be cheaper over the vehicle lifetime to operate an EV. Selecting the right chemistry will be imperative for getting a low enough vehicle price. So why is a clear dichotomy seen between the batteries being deployed in China compared to Europe? Electric vehicles in construction are an emerging market. IDTechEx has built a database of more than 100 example makes and models across seven different construction-vehicle categories: mini excavators, excavators (>6 tonne), compact loaders, backhoe loaders, wheel loaders, telehandlers and mobile

Industrial vehicles such as forklifts, cranes and tractors have come a long way in terms of applying technology, enhancing performance with improved operation and safety. With the advancements in computer vision, robotics and artificial intelligence (AI), these vehicles now are equipped with functionality that utilizes information to support and optimize performance. One of the key enablers of these advances is the integration of machine learning (ML) derived platforms and powerful computers, neural processing units and cameras integrated into the digital system. System designers and OEMs can get started with AI and computer vision using just a standard Ethernet camera and a Cortex A35 dual- or quad-core next-generation display. Using the detection and recognition of objects, designers can implement and train neural networks to realize new solutions for process guidance, automation, augmented reality and operator awareness. For example, the dual-core CCpilot V700 from CrossControl can

Ethernet is widely used among consumer and commercial systems throughout the world, and it is well understood by all levels of end-users. Due to economies of scale, coupled with availability of industrial-grade devices, Ethernet has also become suitable, and often dominant, for many types of more rigorous applications. Unfortunately, industrial-grade Ethernet devices are often associated with high costs and complex network management and configuration requirements.

Cranes for lifting and lowering heavy objects are an important and sometimes essential tool in modern industries such as construction, transportation, and manufacturing. NASA uses overhead and mobile cranes for assembly of load lines employed in full-scale testing of its Space Launch System (SLS), a super-heavy-lift launch vehicle for deep space human space exploration. Structural testing of the SLS requires precision placement of heavy objects with soft contact during mating connections, which proved to be problematic with the relatively coarse control available with motor-driven overhead cranes and the existing rigging devices.
