Request for Proposal: Mars Rover Robot (MRR)
Introduction and Overview
The National Aeronautics and Space Administration (NASA) has recently received strong evidence of volcanic activity on the long-believed volcanically dormant planet, Mars. Radar measurements from the Mars Express spacecraft have detected the presence of a 20 km wide lake of liquid water located underneath a layer of ice in the Planum Australe region. Modern research about the discovery suggests that the only way to maintain water in the liquid state in the conditions present on Mars is with the presence of a magma chamber located underneath the body of liquid water. To explore the possibility of active volcanic activity on the Red Planet, NASA has issued a request for proposal for a Mars Rover Robot (MRR) that is capable of traversing the steep slopes of Olympus Mons, the second tallest mountain and largest volcano in the solar system. This rover will dig near the base of the volcano and photograph it from its peak. By studying the data obtained, NASA hopes to understand the past volcanic activity of the planet and use that data to weigh the possibility of present-day volcanic activity.
The mission has two parts that must be completed. The first part is to collect a rock sample and bring it back to the start tile for analysis. The second part of the mission involves climbing to the peak of Olympus Mons to take a picture of the surrounding environment. To complete the mission, a sensor must be used to increase the accuracy of the rover's movement.
Specifications
Design a robot using Fusion 360 as the primary design tool. The robot must meet the following specifications:
- Size & Material Constraints
- The robot must fit within a 15 in x 15 in footprint.
- The design must use the materials provided. A cost estimate of the robot’s components must be created and all revisions to the cost estimate must be recorded and explained.
- The robot must use no more than two motors.
- Sensor Requirement
- The design must incorporate a sensor. This could be a gyro, ultrasonic, touch or IR obstacle sensor.
- Microcontroller Requirement
- The robot’s movements must be directed by an Arduino program. All revisions to the Arduino program must be recorded and explained.
- Autonomous Navigation
- The robot must be fully autonomous, and so cannot be touched during testing. The Arduino program may not be altered or switched during any part of the mission.
Please refer to the course syllabus for all due dates.
Please note that this project reflects real-life scenarios; the robot must be able to handle minor imperfections in the course. Any attempt to physically step on the course or have the robot drive off a cliff is unsafe and will result in a point penalty in the final project grade.
Course Layout
The MRR course consists of two primary ramps, labeled Ramps 2 and 3, and one additional ramp, Ramp 1. The robot must traverse the uneven terrain to reach the rock sample, return to the Start tile, and traverse Ramps 2 and 3 and come to a complete stop at the peak. For extra credit, the robot can traverse Ramp 1, incorporate an additional sensor, and/or return to the start tile at the end of the run. In completing the extra credit, the robot must descend on the primary ramp for Commissioning. The robot cannot jump off the primary ramp directly to Ramp 1 (Figure 1).
Microsoft Project
A project schedule must be created in Microsoft Project. Learn to use Microsoft Project by accessing the Microsoft Project Student Guide. This schedule must include all tasks related to the project from the start of the project to Early or Final submission. Click here to access the guide on how to transfer a file. The Microsoft Project schedule should include:
- Minimum of 20 tasks, excluding Milestones
- Milestones should be clearly indicated on the project plan (duration of zero days)
- Each task must include the person responsible for completing the task (resource names)
- Use the "Copy Picture" function to include the schedule in the presentations. Do not take a screenshot
- Gantt chart must be displayed alongside the tasks list (fit onto one slide)
- Gantt chart must show a progress line
- Clearly state during the presentations whether the project is on-time, behind schedule, or ahead of schedule
For help planning the project, review the manual page Planning Project Scheduling & Costs.
Drawings
All drawings and sketches should be made using the Assembly tool in Fusion 360. Fusion 360 can be downloaded for free from the Autodesk website using an NYU email or accessed from any computer in the Modelshop during Open Lab hours.
Using Fusion 360, create four drawings of the robot: front, top, most detailed side, and a drawing of the gear train(s). Sensors, motors, and gears must be included in each drawing. Smaller pieces such as nuts, bolts, axles, etc. may be omitted from the drawings.
Each revision of the design must be documented and all changes must be presented during Milestone presentations.
Model
You must build a scale model (1:1) of your design. The following materials will be provided:
- VEX robotics pieces
- Basic electronics prototyping kit
- Sensors
- Motors
The finished MRR must not exceed a footprint of 15 in × 15 in. There is no height limitation. Any additional components that the MRR is equipped with must also fit within the footprint. Additional materials can be supplied by your TA.
Cost Estimate
Once a robot design is complete, a cost estimate must be generated that specifies the cost of all the materials and labor required for the construction of the design. Tabulate this cost information clearly in an Excel spreadsheet, using the materials cost list provided. Help in calculating the cost is available by reviewing how to plan the schedule and calculate costs for a project. The costs for the parts can be found on the Price list for VEX parts for robot projects.
Note: Only the materials contained in the price list for VEX parts for robot projects may be used. To use other parts, get permission from a faculty member, and also to determine the cost of the additional parts used that are not in this price list.
The cost estimate should include the following:
- Labor cost breakdown with hours and rates ($50.00 per person per hour)
- Consolidate low-cost pieces: axles, beams, bricks, bushings, connectors, gears, plates
- Consolidate low-cost electrical components: microcontrollers, breadboard, wires, motor shield
- Itemize high-cost pieces: sensors, motors, and battery
- Total cost must be shown in the bottom right corner of the table
CATME
When working on engineering team projects, peer evaluations and self-evaluations are critical for assessing how effective your contributions are to the team. In our course, your recitation professor will use evaluations at each Milestone using a software called the Comprehensive Assessment of Team Member Effectiveness (CATME). More information can be found on the Teamwork Expectations page.
Engineering Notebook
While working on your project, you are expected to keep a record of all work done, as well as future plans and goals. In order to complete a Benchmark assessment, show your Engineering Notebook to the Open Lab TA completing your assessment. For Milestone 1, Milestone 2, Milestone 3, and Final Submission you must have it approved by your Recitation Professor and be prepared to make it available to an Open Lab TA in a Word Document (DOC or DOCX) format. A guide to writing the notebook, as well as a basic overview of its expectations and frequency at which you should log in your notebook, can be found on the Keeping an Engineering Notebook page.
Extra Credit
Teams can complete the tasks listed below to receive extra credit at commissioning:
- Returning to the starting position at the end of the entire run. If completing multiple extra credit tasks, returning to the start tile should be the final task completed.
- Traversing the secondary ramp (Ramp 1). The robot must be able to descend the primary ramp similar to how it ascended the ramp for commissioning. 'The robot cannot jump off the primary ramp directly to Ramp 1.
- Implementing an additional sensor
Additional extra credit opportunities are as follows:
- Completing Benchmark A, Benchmark B, or Submission early
- Completing MRR's 3D printing Extra Credit task of printing a robot part that will help your robot complete the course your as described in the 3D Printing and Logo Guide
Refer to the EG1004 Grading Policy for exact point values. Creativity and innovation are always rewarded. Original designs will receive extra credit.

Frequently Asked Questions
Q: Can we step on the course as it is difficult to retrieve a robot from the middle of the course due to its size?
A: No. If needed, you can ask a TA to assist you.
Q: Can we bump the course if the robot gets stuck?
A: No. You can't bump Mars, so bumping the course is not an option.
Q: Can we use rubber bands on the wheels for more traction?
A: Yes. This is highly encouraged, especially when dealing with slopes.
Q: All the VEX parts are really big. Is there a size constraint?
A: There is a soft size limitation of a 15 in × 15 in footprint. If you slightly exceed this constraint, it is okay, but you may encounter difficulties in navigating the robot through the course.
Q: Can we use more than 2 motors?
A: No. Robot designs must be restricted to two motors.
Q: Can our robot jump from one hill to another?
A: No. This will cause damage to both the robot and course and is also unsafe. If your robot does this, your trial will be invalidated and you may receive point penalties to your final project grade.
Q: How should I get started with building my robot?
A: For help with building, refer to the VEX How-To Manual.
