NASA’s Perseverance Rover is bringing his own steering wheel for Mars Drive

NASA’s Perseverance rover is picking up its pace on Mars, thanks to technology that helps robots avoid problems with otherworldly units. The
technology, called AutoNav, is a navigation system that can map terrain and plan routes, while the rover doesn’t need to rely too heavily on ground guidance. AutoNav is four to five times more powerful than the equivalent technology tested on Curiosity, NASA’s previous Mars rover, meaning Perseverance will be able to take more direct routes and travel faster, which in turn allows the rover to do so. in the same amount More scientific hour.
“We will be able to get where scientists want faster,” said Jennifer Trosper, Mars Rover Project Manager at NASA’s Jet Propulsion Laboratory (JPL) in California, in a NASA statement. “Now we can drive through these more complex terrain instead of avoiding it – this is not what we used to do.”

will not eliminate human drivers entirely, but will only increase the range of the rover when possible.
“We have a skill called ‘thinking while driving,'” said Vandy Verma, senior engineer, mobile vehicle planner and driver at the Jet Propulsion Laboratory in the same statement. “The rover is considering autonomous driving while the wheels turn.” Other features of the new rover
will also help increase speed. Percy’s wheels have larger diameters, narrower widths, and wider tread patterns, and mission engineers aim to increase traction and durability on Mars. Perseverance is also equipped with a completely independent navigation computer. The new rover has a higher abdominal space and can safely explore more types of terrain.
“This is a rover driver’s paradise.”
Overall, the improvements implemented for Perseverance mean that the rover can reach speeds of 393 feet per hour compared to Curiosity’s speed of 66 feet (20 m) per hour. 120 meters) – a little more than the length of a football field. This will allow Perseverance’s top speed to reach approximately 0.07 mph (0.12 km / h). Increasing the speed of the rover for Perseverance is important because mission scientists want to guide the rover to cover a total of 9 miles (15 kilometers) during its mission.

This is not only exciting for the scientists, but also for the humans who helped Perseverance navigate, as they can enjoy more views of the red planet in Jezero crater.
“Jezero is great,” Verma said. “This is an ATV driver’s paradise. When you put on 3D glasses, you will see more ripples on the terrain. Sometimes I just look at the images.”
