In the third video of the 2015 design series you can see the rocker-bogie suspension system. While this is the same system we used last year, stronger, and more reliable joints are being used together with the redesigned differential and in-wheel motors to obtain a significantly better mobility system in comparison to the previous year. Check out the 2015 rocker-bogie.
As a part of URC 2015, there will be a limit on the number of teams that can participate due to logistical challenges faced in last year’s competition. The final milestone before the competition the team must pass before competition is to complete the critical design review. One aspect of this is a video that demonstrates the progress of the team on its design and construction. Check out our video submission!
Kicking off the video series with multiple videos! This video discusses the in wheel motors designed this year. For those that were not following the team last year, we had an unfortunate mishap in the terrain traversing challenge at the URC in which one motor was no longer rigidly attached to the frame, and another entirely separated from the gearbox and wheel it was driving. While the team was able to rapidly fix the rover in order to complete some more of the challenge. This years design features in wheel motors, and new rocker-bogie arms that minimize the exposure to the elements, rocks, and other anything it could potentially impact. But for more details, check out this video!
This year we are going to be producing regular videos covering different aspects of our design in anticipation of the completed rover. The rover seen in these videos is going to be used by the USST in both the URC, and ERC this year. The first video outlines MARCO Mk II’s differential.
To see the videos first hand please follow the team’s Facebook Page.
Check out some footage from the University Rover Challenge in our new promotional video!
On 2 August, 2014 the team embarked on our first High Altitude Balloon Launch of the year. As last time we worked on collaboration with the Saskatoon Amateur Radio Club. On this launch we fixed the issues with our cameras from the launch last September, and ran a completely rebuilt payload, with nothing the same as last time. The launch demonstrated our communications systems that was run for the first time.
It was also one of the most eventful launches as the payload landed in water. Members worked to retrieve the payload from the water. All the data was still retrieved. When all is said and done, it was a very successful launch.
In case you are interested, footage from the camera on board has been compiled. You will notice how cloudy it was that day, and how much smoke still lingered in the air from the forest fires up north.
This year the team was able to place seventh at the 2014 University Rover Challenge. It was a challenging event that tested the team’s resolve and ability to make changes and repairs on the fly. We would like to thank all of our sponsors and supporters that helped get to the competition. We are looking forward to, and ready for action next year!
Stay posted for updates over the summer as the team works toward next years competition and gears up for the high altitude balloon launches over the summer months.
While we still have a long way to go before we reach our final working rover, here is a snap shot of what has been completed so far.
FOR IMMEDIATE RELEASE
University of Saskatchewan Space Design Team to Compete in Mars Rover Challenge
23 January 2014
The University of Saskatchewan Space Design Team (USST) is officially registered in the University Rover Challenge (http://urc.marssociety.org/) hosted by the Mars Society at their Mars Research Station near Hanksville, Utah. The team members are designing and constructing a rover to participate in this competition, which takes place at the end of May. The USST will be competing against a pool of international competitors in a series of events to test the rover.
The rover is being designed to operate in rough and challenging terrain, perform sample collection and analysis, and complete equipment maintenance and transfer.
The USST is a student group composed of members from the College of Engineering, Edwards School of Business, Computer Science, and Biology. The group is dedicated to developing new space technology by working on projects, and participating in competitions related to the space industry. The USST has proven to achieve excellence through its designs since its formation in 2005.

The USST is now participating in the University Rover Challenge hosted by the Mars Society! We were unable to participate in the NASA Lunabotics competition due to a rule changing preventing us from entering. The University Rover Challenge allowed us keep some of the work, and what we learned from the time we spent on the Lunar Excavator. The goal of the new project is to design a multipurpose rover. For more information see our project page.
