NASA’s Mars Rover Drivers Need Your Help

You may well be equipped to aid NASA’s Curiosity rover drivers greater navigate Mars. Applying the online tool AI4Mars to label terrain functions in pictures downloaded from the Crimson Planet, you can practice an artificial intelligence algorithm to instantly study the landscape.

Is that a major rock to the still left? Could it be sand? Or possibly it is great, flat bedrock. AI4Mars, which is hosted on the citizen science site Zooniverse, allows you draw boundaries all-around terrain and choose 1 of 4 labels. These labels are important to sharpening the Martian terrain-classification algorithm called SPOC (Soil Property and Item Classification).

Designed at NASA’s Jet Propulsion Laboratory, which has managed all of the agency’s Mars rover missions, SPOC labels numerous terrain varieties, creating a visual map that assists mission team users figure out which paths to just take. SPOC is presently in use, but the program could use more coaching.

“Typically, hundreds of hundreds of examples are desired to practice a deep understanding algorithm,” stated Hiro Ono, an AI researcher at JPL. “Algorithms for self-driving autos, for case in point, are experienced with numerous pictures of roadways, signals, visitors lights, pedestrians and other vehicles. Other public datasets for deep understanding comprise people, animals and buildings – but no Martian landscapes.”

After thoroughly up to velocity, SPOC will be equipped to instantly distinguish concerning cohesive soil, higher rocks, flat bedrock and perilous sand dunes, sending pictures to Earth that will make it a lot easier to strategy Curiosity’s upcoming moves.

“In the potential, we hope this algorithm can come to be accurate plenty of to do other practical responsibilities, like predicting how possible a rover’s wheels are to slip on distinctive surfaces,” Ono stated.

The Occupation of Rover Planners

JPL engineers referred to as rover planners may well gain the most from a greater-experienced SPOC. They are dependable for Curiosity’s each individual transfer, irrespective of whether it’s taking a selfie, trickling pulverized samples into the rover’s body to be analyzed or driving from 1 spot to the upcoming.

It can just take 4 to 5 hours to function out a generate (which is now carried out virtually), demanding numerous people to publish and evaluate hundreds of lines of code. The task entails in depth collaboration with researchers as properly: Geologists assess the terrain to predict irrespective of whether Curiosity’s wheels could slip, be destroyed by sharp rocks or get stuck in sand, which trapped both equally the Spirit and Opportunity rovers.

Planners also contemplate which way the rover will be pointed at the conclusion of a generate, due to the fact its high-gain antenna needs a very clear line of sight to Earth to obtain instructions. And they attempt to anticipate shadows slipping throughout the terrain in the course of a generate, which can interfere with how Curiosity determines distance. (The rover employs a technique referred to as visual odometry, comparing digicam pictures to close by landmarks.)

How AI Could Assistance

SPOC won’t replace the challenging, time-intense function of rover planners. But it can totally free them to concentrate on other facets of their occupation, like speaking about with researchers which rocks to review upcoming.

“It’s our occupation to figure out how to safely and securely get the mission’s science,” stated Stephanie Oij, 1 of the JPL rover planners involved in AI4Mars. “Automatically creating terrain labels would conserve us time and aid us be far more productive.”

The added benefits of a smarter algorithm would prolong to planners on NASA’s upcoming Mars mission, the Perseverance rover, which launches this summer. But to start with, an archive of labeled pictures is desired. Much more than eight,000 Curiosity pictures have been uploaded to the AI4Mars web site so significantly, delivering plenty of fodder for the algorithm. Ono hopes to include pictures from Spirit and Chance in the potential. In the meantime, JPL volunteers are translating the web site so that participants who speak Spanish, Hindi, Japanese and a number of other languages can lead as properly.
