Autonomous mobile robots do heavier lifting

ROEQ has launched two new top modules and accompanying accessories designed to boost the payload and lifting capabilities of autonomous mobile robots (AMRs) from industry leader Mobile Industrial Robots (MiR). Capable of handling total payloads of up to 1,500 kg (3,307 lb), the new ROEQ top module TMS-C1500 combined with the new S-Cart1500W shelf cart greatly increases the payload capabilities of MiR's MiR500, MiR600, MiR1000, and MiR1350 AMRs. Eliminating the need for a docking station, the TMS-C1500 can pick up and drop off the shelf cart in free space and with precision. The AMR is never left idling, and it can simply drop off the cart and immediately go and pick up a new one. ROEQ has also launched the top module TML200 with a stroke of 40 mm that can lift and transport crates, pallets, racks, and ROEQ shelf carts.

Inductive vs. optical vs. magnetic encoders: How to choose

It makes sense that when there isn't a need to spend on a high-end optical encoder, the most common thought is to look directly to magnetic encoders. According to HEIDENHAIN, sometimes that's the right move, but when using an inductive encoder is an available option, your search shouldn't be limited to magnetic or optical. Confused? You won't be after reading this informative HEIDENHAIN blog.

How to avoid premature linear screw actuator failure

At their core, electric linear screw actuators deploy mechanical technology such as ball bearings, ball screws, and roller screws that have a finite life. These components do not last forever -- even though that is the expectation of some customers. But how long will an actuator really last? Tolomatic engineers provide a way to calculate, estimate, and size the electric linear screw actuator to achieve the desired life for your application.

Actuator selection: External motor or internal servo motor?

There are key differences between traditional (external motor) and integrated (internal servo motor) actuators. Each technology offers performance advantages depending on the application type and requirements. Knowing how to compare the two will help engineers design machines that meet their requirements.

Cobots in Automotive?

While automotive was one of the first industries to automate its factories, today's OEMs and tier suppliers still have employees managing far too many manual tasks which can lead to bored workers, inconsistent product quality and workplace injuries. This webinar hosted by Universal Robots will help those seeking to learn how collaborative robots are being used in automotive, with specific examples of cobots taking over machine tending, screwdriving, welding, painting and quality inspection tasks.

Ford and Purdue patent alternatively cooled EV charging station cable

Ford Motor Co. and Purdue University researchers have taken an important early step to make recharging EVs simple and time saving.

Through a research alliance, researchers from both groups are working to develop a new, patent-pending charging station cable that could combine with in-development vehicle charging technology to make it easier for people to transition to EVs with seamless recharging.

"Today, chargers are limited in how quickly they can charge an EV's battery due to the danger of overheating. Charging faster requires more current to travel through the charging cable," said Michael Degner, senior technical leader, Ford Research and Advanced Engineering. "The higher the current, the greater the amount of heat that has to be removed to keep the cable operational."

Purdue researchers are focusing on an alternative cooling method by designing a charging cable that can deliver an increased current. The cable uses liquid as an active cooling agent, which can help extract more heat from the cable by changing phase from liquid to vapor -- the key difference between this and current liquid-cooled technology on the market.

This innovation could one day deliver significantly more power than today's leading systems to recharge electric vehicles, making the potential of faster recharging times possible if vehicle charging and other technology enhancements are made in parallel. Ultimately, this could lead to recharging EVs as quickly as conventional gas station fill-ups.

The idea for this technology originated from the Ford team's understanding of the challenges faced when trying to move to faster charging rates, as well as Purdue researchers' area of expertise. The teams collaborate regularly to review the latest results and give feedback on areas of focus as the technology is developed.

"Electric vehicle charging time can vary widely, from 20 minutes at a station to hours on an at-home charging station, and that can be a source of anxiety for people who are considering buying an electric vehicle," said Issam Mudawar, Betty Ruth and Milton B. Hollander Family professor of mechanical engineering, Purdue University. "My lab has come up with a solution for situations where the amounts of heat that are produced are beyond the capabilities of today's technologies."

Mudawar says his lab intends to begin testing a prototype charging cable in the next two years to determine more specific charge speeds for certain models of electric vehicles.

"Ford is committed to making the transition to electrification easy," said Degner. "We are glad to work closely with Purdue's research team, which has the potential to make electric vehicle and commercial fleet ownership even more appealing and accessible."
