The average car is opened and closed 45,000 times over the course of 10 years — sometimes gently, sometimes with enthusiasm, occasionally slammed when you’re having a bad day. Imagine being the worker who has to do that open-close cycling to prove the durability of the door hinges, latch mechanisms, weatherstripping, and window glass frames.
Nissan has enlisted an automated test device, a 1.5-ton door-durability robot, to test car door reliability at the Nissan Technical Center North America (NTCNA) in Farmington Hills, Michigan. The robot is nicknamed Rosie, or Mrs. Doorboto. In three days, Mrs. Doorboto opens and closes a door as much as that typical customer does over the course of a decade, working around the clock, with no coffee, bathroom, or lunch breaks. For all her work (and with apologies to Styx), Nissan says, “Domo arigato, Mrs. Doorboto.”
A Company of Tech Breakthroughs, Cool Options
Nissan is more than robotic door testers. It has been a company with intriguing technologies. It is the top seller of electric vehicles. It has a home charging system with the ability to feed the Leaf’s battery power back to the house during a blackout. A second version uses recycled EV batteries as a home backup power source.
Nissan’s home energy storage can charge a Leaf or use the Leaf’s batteries to power a house for 1-3 days.
Nisan was the strongest supporter of continuously variable transmissions (CVT) as the bugs were being worked out; now many others use CVTs, too.
Nissan was out early with 360-degree camera systems (Around View Monitor). It was first with Easy Fill for adding air to tires, in the 2013 Nissan Altima sedan.
Rogue Dogue concept SUV.
At the New York Auto Show, Nissan showed the Rogue Dogue concept car, a Nissan Rogue compact SUV with the cargo area outfitted with a doggie mattress, rear compartment HVAC vents, slide-out food and water dispensers, and a slide-away ramp to help the pooch get in and out of the car. If the dog gets dirty (it happens), there’s a 10-gallon water tank with sprayer for washing Fido and a compressed heated air dryer.
