Newsletter Mai 2021

Dear supporters of WARR Exploration,

We are back with a new newsletter to update you on our progress towards the IGLUNA 21 Field Campaign. Due to Corona, we had a hard time manufacturing our rover LARSS as only three people were allowed to enter our WARRkstatt. Despite this, we managed to manufacture the rover before the Readiness Review which is going to take place on the 4th of June. Now, our electrical engineers and programmers are integrating the motors and PCBs, fixing some small last bugs, and testing everything to ensure smooth functioning at the field campaign. Below, you find some images taken during manufacturing.

We are looking for new members

To all TUM students passionate about space exploration, we are looking for you. Join our highly motivated and interdisciplinary team to design a future rover. At WARR Exploration, you will gain hands-on experience in designing, developing, and manufacturing a rover to demonstrate space exploration applications. You will start right away with building an ExoMy (a small version of the Mars Rover of ESA and Roskosmos) as part of your introductory phase. For more information, visit our kick-off on April 26th at 6 pm CEST, or simply contact us via E-Mail or our social media channels. Kick-Off: (26.04.2021, 18:00 CEST)

Newsletter December 2020

Dear supporters of WARR Exploration,

During such difficult times good news is rare, but fortunately we have some: We passed the delta PDR for IGLUNA 2021 and are now on track to convince our reviewers once more at the CDR, which will take place virtually on February 19th. Unfortunately, our workshop had to be closed completely from December 8th onwards; it is not clear when we are allowed to work there again. But we hope that the lockdown will end on January 10th.

Nevertheless, we wish you and your family Merry Christmas and a Happy New Year!

Stay healthy,

Your WARR Exploration team

Despite the tough social distancing restrictions on working in our workshop, we managed to finish our prototype. Furthermore, we published our new promotional video, which you can watch on YouTube.

Propulsion and Chassis (PC) is currently developing a new iteration of its system. Based on the existing prototype, new functions will be added and old ones will be improved. One such feature will be a torque motor to actuate the steering movement. Its short axial length will allow us to drastically lower the rover’s center of mass.

Structural parts of the new rover will be manufactured using more sophisticated methods. FEM analysis and topology optimization will assist us in optimizing the geometry of the parts and reducing the weight of the rover. We will also integrate the electronics housing into the suspension design, which will reduce weight, size, and the risk of collisions with other parts of the kinematic system.

Newsletter November 2020

We hope that you are all healthy and not too bad affected by the “Lockdown light”. Due to this lockdown, only two members of WARR Exploration are allowed at the same time in our workshop. Fortunately, we had finished most of the manufacturing by the time the lockdown started. Currently, only the electronic and the payload team need to manufacture parts, so we are still confident about meeting our deadlines and have a competitive rover for the IGLUNA field campaign.

Recent Works

We are proud to announce that we have completed the first iteration of our student documentation for IGLUNA. The student documentation is a comprehensive report that describes all aspects of our project, from the technical description of the rover itself to all project management issues. We look forward to the defense presentation (the Preliminary Design Review) associated with the documentation, which we will deliver this Tuesday in front of experts from the Swiss Space Center.

Approaching the main design phase of the IGLUNA project, the Payload team and Propulsion and Chassis team have been working closely together to find out how to integrate the sintering apparatus onto the rover. This design allows the printing axes to be independent of the movement of the solar tracking axes. Therefore, the solar tracking system can function automatically while the printing is controlled by the user using G-Code. With these insights, the payload team can begin their detailed mechanical design.

In the meantime, Payload is also experimenting with different mixtures of sand to use for demonstrating the functionality of our rover. Here you can see the latest one, which consists of 90% quartz sand and 10% soda. Currently, the main difficulty is finding a sunny day for testing, as we are reliant on strong sunshine for sintering.
