First to use robotics for extreme test driving, says Ford

A single human operator can control and collect data from up to eight robots, says Ford Malaysia's national sales manager.

According to the Ford Motor company, it is the first automaker to develop robotic technology that drives vehicles during new accelerated high-impact on-road and off-road durability testing.

"Using robots enables Ford to perform extreme durability testing on Ford trucks that may be too dangerous for human drivers," said Veemala Rethinasamy, Malaysia national sales manager, Asia Pacific, Ford Export & Growth Operations.

"It also enables greater operational efficiency - a single human operator can control and collect data from up to eight robots, improving Ford's tough trucks safely and economically," said Rethinasamy.

Developed by Ford engineers, the new technology is being used to check that its trucks, including the new Transit van family meet the company's 'Built Ford Tough' objective. The pilot programme has been used most recently for durability testing of Ford's all-new full-size Transit van, which launches in 2014.
 
"Some of the tests we do on our commercial trucks for North America are so strenuous that we limit the exposure time for human drivers," said Ford manager, vehicle development operations, Dave Payne. "The challenge is completing testing to meet vehicle development timelines while keeping our drivers comfortable.
 
"Robotic testing allows us to do both," Payne said. "We accelerate durability testing while simultaneously increasing the productivity of our other programmes by redeploying drivers to those areas, such as noise level and vehicle dynamics testing."

He said the durability technology includes a robotic control module installed in the test vehicle that controls vehicle steering, acceleration and braking. The module follows a preprogrammed course, and the vehicle's position is tracked via cameras in a central control room and GPS accurate to plus/minus one inch. Should the vehicle stray from its programmed course, engineers have the ability to stop the vehicle, course correct as necessary, and restart the test. Onboard sensors can command a full stop if a pedestrian or another vehicle strays into the path.
 
Compressing 10 years of driving

Ford's robotically driven vehicles repeatedly perform tests on torturous surfaces with names like Silver Creek, Power Hop Hill and Curb Your Enthusiasm. The tests can compress 10 years of daily driving abuse into courses just a few hundred yards long, with surfaces that include broken concrete, cobblestones, metal grates, rough gravel, mud pits and oversized speed bumps.
 
 All North American Ford trucks must pass this battery of durability tests before they're certified for customer use. Until now, testing speeds and repetitions for specific scenarios were limited due to restrictions placed on human drivers, who were allowed to drive certain rigorous courses only once a day.
 
The use of robots now accelerates this testing, allowing an unlimited number of repeats until Ford engineers are satisfied with the results. Robots also allow Ford to develop even more challenging durability tests to build tougher trucks.
 
Ford engineers worked with Utah-based Autonomous Solutions Inc. to design and manufacture the software and components that enable autonomous, robotic operation of the test vehicle.

"We're very excited to work with Ford for autonomous vehicle testing," said Autonomous Solutions chief executive officer, Mel Torrie. "The reliability, durability and performance enhancements we've developed with Ford will not only help them reach their safety and accuracy goals, but will also improve vehicle automation in other areas such as mining, agriculture and the U.S. military."
 
"The goal here was not to develop a truly autonomous vehicle that can drive itself on city streets," said Ford's Payne. "Our objective was to create a test track solution that allows for this type of intense testing that could take our vehicles to the most extreme limits of their engineering while ensuring the safety of all involved."
