Lunar Agricultural Zone (LAZ)

Request for Proposal: Lunar Agricultural Zone (LAZ)

Introduction and Overview

Humanity faces the problem of feeding its growing population. Currently, half of the Earth’s habitable land (51 million km²) is used for agriculture, leaving little for much else. To combat this, the National Aeronautics and Space Administration (NASA) has turned to lunar agriculture. With a surface area of over 37 million km², the moon has the potential to produce over 70% of the Earth’s current food supply. Due to the slow period of rotation, stationary crops on the moon will be exposed to 27.3 days of continuous sunlight and then darkness. To have greater control over the sunlight exposure of crops on the moon, NASA has issued a request for a proposal for an autonomous rover that is capable of traversing the Lunar Agricultural Zone (LAZ), the newest solution to world hunger. This rover would traverse the unsmooth terrains of the moon, locate various crops, and determine if they should be moved depending on the levels of light exposure detected. By keeping rigorous control of the light exposure of the crops, NASA hopes to create an environment capable of sustaining plant life on the moon.

The objective of this mission is to locate and collect all plants in the LAZ that are overexposed to sunlight. To complete the tasks, a gyro, touch, or ultrasonic sensor can be used to increase the accuracy of the rover's movement. After the overexposed plants are obtained, they should be transported to an area of less exposure.

Specifications

Design a robot using Fusion 360 as the primary design tool. The robot must meet the following specifications:

• Size & Material Constraints
  • The robot should ideally fit within a 12" x 12" footprint. Larger robots are allowed but discouraged.
  • A cost estimate of the robot’s components must be created and all revisions to the estimate must be recorded and explained.
• Build Guidelines
  • The mechanism used to pick up the samples must be designed and built (the use of prebuilt VEX claws is prohibited).
  • Projectile (catapult, slingshot) designs are not allowed.
• Sensor Requirement
  • The design must incorporate a sensor of choice. This could be a gyro sensor, ultrasonic sensor, or touch 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 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.

This project aims to reflect certain real-life scenarios. The robot must therefore be able to handle minor imperfections in the course. Please note that any attempt to physically step on the course is unsafe and will result in a point penalty in the final project grade.

Course Layout

The LAZ course consists of three plant module pickup sites and the corresponding drop sites. The robot must pick up Plants 1 and 2 and drop them off at the corresponding location to complete the project. For extra credit, the robot can pick up Plant 3 and move it to the drop site and/or move Plants 1 and 2 back to the pickup sites. The robot must use a fully autonomous claw to pick up the plant modules and drop them off (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 project plan in the presentations. Do not take a screenshot.
• Gantt chart must be displayed alongside the tasks list (fit onto one slide).
• Gantt chart must clearly show a progress line.
• Clearly state during the presentation whether the project is on-time, behind schedule, or ahead of schedule.

For help in planning the project, review the manual page How to plan the schedule and calculate costs for a project.

Drawings

All drawings and sketches should be made using the Assembly tool in Fusion 360. It can be downloaded for free on a personal computer using an NYU email or accessed from any computer during Open Lab.

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, and axles may be omitted from the drawings. If the robot does not use any gears, make sure to explicitly state that in the presentations.

Each revision of the design must be documented and all changes must be presented during Milestone presentations (Figure 2).

Model

Build a scale model (1:1) of the design. The following materials will be provided:

1. VEX steel pieces
2. Basic electronics prototyping kit (Reference VEX wiring guide)
3. Sensors
4. Motors

The finished robot must not exceed a footprint of 12" × 12". There is no height limitation, but be mindful of the risk of toppling. Additional materials can be supplied by a TA. An example of a LAZ robot model is shown in Figure 3.

Figure 3: Example LAZ Robot Model

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. 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 electrical components: microcontroller, breadboard, wires, battery, motor shield
• Itemize high-cost pieces: sensors and motors
• No decimal places; this is an estimate after all. Round appropriately
• Total cost must be shown in the bottom right corner of the table

Note: List only the materials from the price list for VEX parts for robot projects. To use other parts, and to determine the cost of the additional parts that are not in this price list, get assistance from a TA.

CATME

When working on engineering team projects, peer evaluations and self-evaluations are critical for assessing how effective your contributions are to the project. In this course, the 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

All work done on the project and future plans and goals must be documented in an Engineering Notebook. To complete a Benchmark assessment, the Engineering Notebook must be presented to the Open Lab TA completing the assessment. For Milestone 1, Milestone 2, Milestone 3, and Early or Final Submission, the Engineering Notebook must be approved by the 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 and a basic overview of the expectations and frequency at which the Engineering Notebook must be updated can be found on the Keeping an Engineering Notebook page.

Milestones, Benchmarks, and Deliverables

As work is done on the project, three Milestone presentations will report on the project's progress. All of the items assigned in each phase of the project are called Benchmark deliverables. These deliverables often consist of a combination of written submissions, presentations, and demonstrations. Benchmark assessments evaluate the progress of the project.

Frequently Asked Questions

Q: Is stepping on the course allowed as it is difficult to retrieve a robot from the middle of the course due to its size?

A: No. If needed, ask a TA for assistance.

Q: Can the course be bumped if the robot gets stuck?

A: No. It is not possible to bump the Moon, so bumping the course is not an option.

Q: All the VEX parts are really big. Is there a size constraint?

A: There is a size limitation of a 12 in x 12 in footprint. Exceeding this constraint is okay, but it may create difficulties when the robot is navigating the course.

Q: What is a common mistake to avoid?

A: Starting the project late. Note that Benchmark A requires a robot with a functioning claw mechanism and building VEX robots can be tedious.

Q: What is the best way to build the LAZ Claw?

A: For help with claw designs, refer to the VEX Lift & Claw Design Guide.

Q: What materials can be used use for the VEX Claw?

A: EG’s LAZ inventory includes Linear Motion Kits, Sprockets & Chains, and Tank Treads. These materials have limited availability, so first come, first serve.

Q: How can the VEX robot's performance be more consistent?

A: Sensors are very helpful when it comes to consistency. Additionally, use the walls on LAZ course to align the robot. Just make sure the robot is not ramming into the course, which can damage it.

Q: The robot is having a hard time making turns on the course, how can that be fixed?

A: Each LAZ design is allowed to use two omni-wheels, which help robots make turns more easily. Adding clear tape onto the regular VEX wheels also helps.
