Welcome week started off with the Club Expo in the Usask Bowl and ended with a wonderful pancake breakfast before our new member orientation and first design meeting of the semester in the Engineering Hardy Lab.

Our team had a great showing at the second annual Canadian International Rover Challenge.
Our team only had 55 days between returning from the University Rover Challenge in Utah and leaving for CIRC in Drumheller. In this time we had to modify our rover to operate in the two new tasks at CIRC, the resource extraction and night search and rescue tasks.
Our team built a linear actuator driven front end loader attachment for our rover. Our loader had integrated load cells, allowing us to weigh our payload to approximately +/- 5 grams.
Our search and rescue modifications included a custom student built 360-degree infrared camera; high power LED lights, a yagi antenna to track an emergency radio beacon, and a holster to carry oxygen tanks, space suit repair kits, a light beacons.
Our rover came in second in the Search and Rescue task and fifth overall in the Canadian International Rover Challenge. We had a wonderful lime competing and getting to know the other rover teams from across the globe.
Our team has just returned from competition in Utah, placing 18th out of 98 teams.
The extensive use of carbon fibre on our rover has lead to a larger and lighter rover with an extremely low centre of gravity. This lead to an outstanding rock and sand dune climbing ability and made the rover an incredible machine to drive through the desert.

The 2,100 kilometer trip from Saskatoon to Hanksville, Utah was a challenge all on its own, featuring multiple areas of road construction, detours, a blown transmission seal, and a tire change.
A huge thanks goes out to the Montana Highway Patrol for their assistance when we were broken down in a dead zone on the side of the I-15.
Our design teams have received both validation and found improvements for their designs as we prepare for the Canadian International Rover Competition in August.
We are proud to announce our involvement in the upcoming 4-year Canadian CubeSat Project. We have partnered with the University of Saskatchewan and Saskatchewan Polytechnic to build a 10x10x20 cm satellite, which will be launched from the International Space Station in 2021. The satellite will include a science payload designed to study the effects of a space environment on a variety of materials, such as plastics, ceramics, fabrics, and more.

Space Team VP of Engineering, Seamus Woodward-George, assembled the last of his Cycloidal Drive gearboxes this week.
The gearboxes took months of design work and multiple 3D printed and laser cut acrylic prototypes (shown in the video below) to perfect.
The production gearboxes were machined out of solid aluminum by the UofS Engineering Shops and perform excellently with our brushless motors.

RLee (from the Department of Chemical and Biological Engineering) demonstrated his large and multistage model rockets which were a joy to watch.
Thank you to the Create Cafe 3D Printing, Express Hobbies, and the Hub City Radio Control Club for making our rocketry project possible.
The parts for our 3D printed rockets arrived from Create Cafe this week and our new members began assembling them today. They have learned a lot about the importance of dimensioning and the advantages of rapid prototyping.
Stay tuned for the launch next week! (weather dependent)

Happy Thanksgiving from all of us at the UofS Space Design Team!
We are greatful for all the the community and industry support we have and continue to receive!
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.
