When the coed leaders of the Northeastern College Mars Rover Crew determined they have been going to take part within the inaugural Winter Canadian Worldwide Rover Problem, they thought it could be good apply greater than the rest.

They didn’t anticipate to win the competitors. But, that’s precisely what occurred.

The Northeastern group took dwelling the gold final month, beating McMaster College for the highest spot with a rating of 237.71 factors to McMaster’s 137.13.

“It was fairly large for us when it comes to group morale,” mentioned Brooke Chalmers, a third-year pupil at Northeastern and the mixing lead and software program co-lead for the Mars rover group. “It actually felt like all of the hours that we put in through the prior weeks paid off in a means.”

It’s the primary competitors win for the six-year-old membership, which consists of scholars learning pc science, engineering, and life science.

The college group of about 50 college students had been exhausting at work creating and iterating on its newest robotic rover: the Watney, Mark V. 

Coming in at 50 kg (110 lb.), the rover encompasses a 5052 aluminum alloy chassis, six 3D-printed nylon wheels, a robotic arm with end-of-arm tooling (EOAT), a life-detection module for pattern assortment, and 14 onboard cameras. 

The Canadian competitors was damaged up into 4 challenges designed to place college students’ rovers via simulated environments much like duties a rover may need to finish whereas on Mars’ floor. Every problem was ranked utilizing a 100-point scale.  

Within the Arm Dexterity Problem, for instance, college students have been tasked with controlling the rover’s robotic arm to revive energy to a campsite. The problem concerned navigating the robotic via 4 management panels the place the robotic arm needed to press buttons and flip switches, defined Jason Kobrin, a fourth-year pupil at Northeastern and a mechanical operations co-lead for the Mars rover group.

Northeastern group redesigns robotic arm for energy

Of the 4 groups participating within the problem, Northeastern scored the best for the problem, with a rating of 49.49 factors. 

Kobrin mentioned the group has spent the previous yr finishing redesigning the robotic’s arm, which was one of many rover’s weak factors throughout earlier competitions. It’s now one of many rover’s greatest strengths. The robotic arm has six levels of freedom and might carry hundreds as much as about 10 kg (22 lb.). 

“With the intention to enhance that, we redesigned our arm this yr to make use of higher motors and to be simpler to regulate general,” he mentioned. 

It’s by participating in these competitions and thru common testing the place the group was in a position to slim in on the rover’s shortcomings and enhance its capabilities, Kobrin mentioned. By engaged on the rover, college students are additionally getting the chance to enhance their very own expertise. 

“Each week, it’s steady enchancment,” he famous. “Whether or not it’s including a brand new portion of software program code [or] whether or not designing a brand new mount for our cameras, each little enchancment makes an enormous distinction.” 

“For everyone to have the ability to design and construct this robotic to operate properly but in addition to have the ability to management it in high-pressure conditions and to achieve the targets we have been searching for to achieve, is simply actually spectacular,” added Kobrin. 

The group thought the two-day occasion hosted in Niagara Falls, Ontario, could be an ideal primer to check out the capabilities of the machine earlier than the group took half within the upcoming annual College Rover Problem (URC). The URC is the Mars Society’s premier Mars rover pupil competitors held on the Mars Desert Analysis Middle outdoors Hanksville, Utah. 

The URC competitors is previous hat for the group, having participated within the problem in 2019, 2022, and 2023. The competitors was canceled in 2020 and 2021 due to the pandemic.

“We went into this competitors pondering, ‘OK, we’re going to make use of this as a chance to organize for URC. We’re going to check stuff to verify all of it works,’” Chalmers mentioned.

Troublesome terrain and group pleasure

The group had its finest displaying through the Winter Transversal Problem, with a ending rating of 84.72 factors. For the problem, the rover needed to roll via treacherous and uneven terrain whereas avoiding obstacles.

“All of the challenges concerned a point of the rover driving round and transferring over troublesome terrain, however this problem was targeted totally on that,” mentioned Chalmers. 

With the general win, Chalmers mentioned she’s hopeful that new members will probably be excited to affix. 

“Most individuals on the group have been speaking about this with their family and friends and speaking about what we’re doing, which is actually cool,” she mentioned. “I do know a couple of of my associates have expressed curiosity in becoming a member of the group since. It’s very thrilling to have one thing to speak about and have one thing to point out for all the hassle we put in.”
