General Motors and University of Michigan develop automated safety features

October 24, 2019 by David Edwards

As General Motors moves toward its vision of a world with zero crashes, the company is partnering with the University of Michigan Transportation Research Institute to understand the real-world effectiveness of some of its available active safety, driver assistance, and advanced headlighting features that may prevent or mitigate different types of crashes.

The company says results show that several of these features are making a statistically significant impact in helping to reduce crashes.

The study leveraged 3.7 million GM vehicles across 20 different models from 2013-2017. Fifteen different systems were evaluated using police report crash databases available to UMTRI from 10 states. [Read more…] about General Motors and University of Michigan develop automated safety features

Public policy group calls for updating of laws to enable driverless truck platooning

July 23, 2019 by David Edwards

A US public policy organization called the Competitive Enterprise Institute is urging states to update their laws to enable driverless truck platooning.

The CEO says the measures would offers safety, economic, and environmental benefits.

New automated vehicle technology will help freight truck companies transport consumer goods in a more fuel-efficient way, reducing transportation costs and emissions and boosting highway safety thanks to always-on automatic emergency braking.

Rough seas: Resistors for severe environments

February 9, 2017 by Sam Francis

Resistor liquid cooling boosts 3.3kV medium voltage loads, and slashes resistor footprint in industrial and marine applications, as David Atkins, projects director at Cressall Resistors explains

In motor driven applications like cranes, lifts, hoists and conveyors, air cooled resistors are common, but in medium voltage, high power applications liquid cooling wins out.

A medium voltage drive running off a 3.3kV supply to turn a 500kW motor will put a severe heating load on the application’s power transistors – hence the need for water cooling.

The new EV2 advanced water cooled modular resistor range for low and medium voltage applications is especially designed to function in severe environments, like the ones marine systems have to function in.

This patented design encapsulates and completely separates the resistor elements from the coolant. [Read more…] about Rough seas: Resistors for severe environments

Braking resistors that will not break

February 1, 2017 by Sam Francis

David Atkins, projects director at Cressall Resistors, explains why design is essential not only in art, but also in industry, especially when designing equipment such as power resistors for demanding environments like oil and gas

One of the most popular works of Renaissance sculpture is Michelangelo’s David, a piece that has become synonymous with human strength and beauty.

Despite its seemingly perfect proportions, a basic design flaw of the statue has recently been brought to light.

Recurring micro-fractures in the ankles might cause the statue to collapse under its own weight. [Read more…] about Braking resistors that will not break

Industrial power: The road to energy efficiency starts here

Leonardo da Vinci robot drummer — Leonardo da Vinci sketched a large number of mechanical ideas, including this robot drummer

Tony Young, owner and director of supply and repair specialist CP Automation, explains how easy it can be to make industrial applications more energy efficient by using regenerative braking

Did you know the invention of robots dates back to XVth century?

When Leonardo da Vinci explored the idea of the human body as a machine, he came up with a robotic knight – medieval armour designed with gears, wheels, pulleys and cables that allowed it to move its arms and legs.

Premature inventions like this one populate the engineering landscape to this day, often when it comes to energy-saving technologies such as regenerative braking. [Read more…] about Industrial power: The road to energy efficiency starts here

The wheel robot: intelligent modular actuator concept

Wheel robots

The wheel robots are for the larger part derived from the Mars rovers, which have actuators integrated into the wheels to help with the movement on the rugged grounds in space. This is made possible with the help of 12 volt linear actuators.

There is some elemental aspects of robotics that are involved in the setup. For there to be synchronous movement on a ground that is not evenly leveled, there is need for each of the units to have its own local control unit.

The local control units are then connected to the central control unit to make sure that they all are moving in the same direction, despite the fact that the wheels they control are experiencing variance in travel and elevation.

Chicago Auto Show: Robots rev up their engines in preparation for final victory over human drivers

February 12, 2016 by Abdul Montaqim

Autonomous cars have already taken over the world and are on the verge of making their final, decisive manoeuvre to eject humanity out of the driving seat. The machines have achieved their domination by using the humble and unsuspecting traditional car as their primary instrument of deception.

That’s according to David Sloan, Chicago Auto Show general manager, although he may not have put it in those exact words. Speaking to Chicago Sun-Times, Sloan says: “People might be surprised to know that most of the technology that will be used to make car autonomous in the future is already in cars today on our show floor.”

Surprised? Try shocked and terrified.

Sloan goes on to say: “All the safety technology that allows cars to automatically brake or park, even adaptive cruise control, is there. Vehicles are now safer, cleaner and more efficient than they have ever been and automakers are still able to make them perform really well. The technology is rapidly advancing, and we’re ready for it.” [Read more…] about Chicago Auto Show: Robots rev up their engines in preparation for final victory over human drivers
