Valveless Hydraulics Cuts Fuel Consumption in Construction Vehicles
Purdue University professor Monika Ivantysynova and doctoral student Naseem Daher discuss research related to new hydraulic steering technology, while graduate student Michael Sprengel looks over the electronic controls of a front loader. Researchers led by Ivantysynova, a fluid systems professor at Purdue's School of Mechanical Engineering, have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment.

An interesting idea. There would be less plumbing; fewer hoses to dry out, seals to fail and losses from the hoses flexing during actuation. I wonder if there is a weight benefit from the reduced plumbing too.
Some of our culture's most enduring robots appeared in the 80s. The Aliens series produced another evil android, and we saw light robot fare in the form of Short Circuit. Two of the great robots of all time also showed up: The Terminator and RoboCop.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
