When the scholar leaders of the Northeastern College Mars Rover Workforce determined they have been going to take part within the inaugural Winter Canadian Worldwide Rover Problem, they thought it will be good apply greater than the rest.
They didn’t count on to win the competitors. But, that’s precisely what occurred.
The Northeastern team took home 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 big for us when it comes to staff morale,” mentioned Brooke Chalmers, a third-year scholar 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 in the course of the prior weeks paid off in a approach.”
It’s the primary competitors win for the six-year-old club, which consists of scholars finding out laptop science, engineering, and life science.
The university staff of about 50 college students had been laborious at work creating and iterating on its newest robotic rover: the Watney, Mark V.
Coming in at 50 kg (110 lb.), the rover contains 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 competition was damaged up into 4 challenges designed to place college students’ rovers by way of simulated environments just like duties a rover might 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 by way of 4 management panels the place the robotic arm needed to press buttons and flip switches, defined Jason Kobrin, a fourth-year scholar at Northeastern and a mechanical operations co-lead for the Mars rover group.

Northeastern staff 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 staff has spent the previous 12 months finishing redesigning the robotic’s arm, which was once 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 may carry hundreds as much as about 10 kg (22 lb.).
“As a way to enhance that, we redesigned our arm this 12 months 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 staff was in a position to slender 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 nicely but in addition to have the ability to management it in high-pressure conditions and to succeed in the targets we have been in search of to succeed in, is simply actually spectacular,” added Kobrin.
The staff thought the two-day occasion hosted in Niagara Falls, Ontario, can be an excellent primer to check out the capabilities of the machine earlier than the staff took half within the upcoming annual College Rover Problem (URC). The URC is the Mars Society’s premier Mars rover scholar competitors held on the Mars Desert Analysis Heart exterior 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 considering, ‘OK, we’re going to make use of this as a possibility to organize for URC. We’re going to check stuff to verify all of it works,’” Chalmers mentioned.

Tough terrain and staff pleasure
The staff had its greatest exhibiting in the course of the Winter Transversal Problem, with a ending rating of 84.72 factors. For the problem, the rover needed to roll by way of treacherous and uneven terrain whereas avoiding obstacles.
“All of the challenges concerned some extent of the rover driving round and shifting over tough terrain, however this problem was centered completely on that,” mentioned Chalmers.
With the general win, Chalmers mentioned she’s hopeful that new members can be excited to hitch.
“Most individuals on the staff have been speaking about this with their family and friends and speaking about what we’re doing, which is admittedly cool,” she mentioned. “I do know a couple of of my mates have expressed curiosity in becoming a member of the staff since. It’s very thrilling to have one thing to speak about and have one thing to indicate for all the trouble we put in.”
