General Outline Objective:
● 5 MINUTES TOTAL!! So we’ll practice timing and that give us 27 seconds each!!
● Each section has a general estimate for time that equals to 257

Desired performance outcomes/Objectives - Fernando
● Retrieve the the highest number of small, medium and large rocks
● Rescue all four rovers, regardless of orientation and state of disrepair
● Our design philosophy was to efficiently utilize our budget so that we are under the
estimated budget of 600 million

Planning and Design - Nikki, Ethan, Eric
Eric: We meet the basic MARSUV Criteria for the rock retrieval mission and kept our
design as minimal as possible.
::Our initial design concerns were with meeting the MARSUV Rover specifications. Right from
the start, our ideas focused on simplicity. That paradigm whelmed all aspects of our design
process. When developing system solutions we attempted to minimize possible failure points
but reducing the number of processes down to the minimum necessary to complete specified
tasks. To further explain our designs, I’m going to turn it over to our Assembly and software
engineers.

2. NIkki: The team collaborated and determined that the best Robotic arm design for the
rock retrieval mission consisted of a gate and a cage. The swinging “gate” combined with the
cage allowed the rover to gather multiple rocks at a time with ease. For the Rover retrieval
mission, we decided that the swinging gate would be ineffective in gathering rovers of different
sizes and shapes.. To address this problem, we rotated the gate and attached it to a motor so
that it would open and close from the side, trapping the rovers in place.
Ethan:
The software onboard the rover is minimal. The programs use a simplistic sequential
flow and each have less than 6 lines of code. At first, the difficult problems that we were trying to
solve--utilizing sensors-- proved nonexistent during testing. In the end, the most effective
approach for the rover was to head in a straight line without sensory input, activate its catching
mechanism and head straight back.

Prototype Testing & Modifications of Rock Retrieval - Derek and Salar
Derek: During the testing phase of the Rock Retrieval mission we tested multiple iterations of
gate design and learned from each failing test. From the tests we found three critical issues: the
first issue was that our double-hinge gate did not keep the rock trapped inside, the second issue
was that the rock would fall out from the sides. Lastly, the third issue we encountered was that
the horizontal front gate clashed with curved martian surfaces and unbalanced the rover.
Salar:
We modified our rover as we encountered these issues to improve our model. We used a
one-pieced solid door for the gate in order to trap the rocks.To address the second issue we
used two pieces of rubber bands on each side to minimize losing the rocks from the sides.
Lastly we added two light-weighted wheels across our gates to help the rover to maintain its
balance as it traversed curved surfaces. As we tested our rover, we grew from each failures.
​Prototype Testing & Modifications of Rover Rescue - Juli and Shanika
25 Seconds
Juli: For the second phase of this project, the Rover Rescue mission, we tested a multitude of
designs to determine the pros and cons of each, and then chose the most effective design. As
Nikki stated earlier, we realized the gate would not be an effective design for different sized
rovers. The next design option that we tested was a claw that would swing down and capture
the rover; we realized that this would not be an effective design because it would cause the front
of the robot to be very heavy and could cause the robot to tip over. The final design that we
tested was the one we chose to use: a side-swinging claw that would trap the rovers inside of
the cage.

3. Shanika: In addition to modifying the robotic arm, a triangle structure was added to the sidebar
to minimize the risk of the buggy falling over the side. We also added a skirt made of tape
underneath the brick to stop rocks from sliding underneath the vehicle. We felt this design would
be more effective at trapping an object with an unpredictable size and structure.

Overall Budget along with points earned for missions and challenges your team face - Corrie
The simple design of our rover allowed for us to optimize our budget. I expected us to break
even during the design and assembly of our prototype rover, however we came out under
budget at 370 million. After the success from our first mission, we had a total of 574 million for
modifications for the rover retrieval project. Our modifications were marginalized to 33 million,
allotting us 541 million left in our budget.

Lessons Learned ​One person to speak on this; need volunteer Erin
From the first discussion board post, we knew we had a team of predominantly strong and
colorful personalities. Throughout this competition we have learned how to listen to everyone's
input and collaborate while working efficiently to meet our objectives. We have learned valuable
technical and soft skills which will lend well into our individual futures.

Public Outreach and education plans - Erin
The first day, after assigning roles within Redolution, we set up: a Facebook page,
Twitter Account and Instagram as a method of community outreach. Our facebook page has
over 200 likes with unique, quality content. Our Twitter page has over 160 tweets. Our goal was
to provide an inside look at The Redolution team process and create awareness of the NASA
Community College Aerospace Scholars program.

Conclusion​ ​One person to speak on this: Fernando
Our team would be honored to be awarded the contract for the next Mars Rover Mission.
We have poured our heart and soul into this project, and have met and exceeded personal
expectations.
Our team stands out because each member contributes successfully to meeting our
objectives and creating an environment where we can speak, collaborate and take risks. Each
failure has become a stepping stone towards our success.
