The Sakura is "very compact, as it has to go down stairways just 70cm wide and turn around on landings that are also 70cm," Eiji Koyanagi fuRO's vice director, told DigiInfo TV at Japan Robot Week last month (watch the video below). "Coolant water is leaking from somewhere inside the reactor, because no matter how much water is pumped in, the level doesn't stay above 60cm. But unless that space can be filled with water, the melted-down fuel rods can't be removed safely, so Sakura's first job is to find out where the cracks are."
Its developers say the robot is especially adept at negotiating stairs and ramps, including changes in slope. "The part [of the buildings] above ground slopes at 40 degrees, and that below ground at 42 degrees," Koyanagi said. "This difference of just two degrees is very hard for a robot to handle. What's more, Sakura has to climb down and then climb up to the top of the suppression pool. That stairway slopes at 53 degrees."
He said fuRO expects to test the robot's mobility and durability in the next month or so. "Once that's done, we'll test its ability to carry the necessary equipment on a stairway. Then we plan to fine-tune Sakura by testing it with TEPCO."
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
