Search & Recovery Robot (SRR)

RFP*: Autonomous Underwater Vehicle (AUV)

* RFP is an acronym for Request For Proposal. Internationally, RFPs are called ITTs, an acronym for Invitation To Tender governmental agencies use RFPs to solicit new business.

Introduction and Overview

In 2007, meteor Billy1987 collided with the International Space Station (ISS). The ISS orbits the moon and is a research facility assembled in space and formed among the space agencies of the US, Russia, Japan, Canada and eleven European countries. During the collision, several pieces of the ISS landed on the Moon, including "Zarya", the power supply module. NASA has issued an RFP for the development of a cost-effective autonomous robot that will retrieve Zarya. The robot should be compact in size in order to fit into the space shuttle. It will be released from the shuttle, land on the moon, traverse through the debris, retrieve Zarya, and return back to its landing site where it will take off back to the space shuttle.

Specifications

Design a robot using MLCad as your primary design tool. Your team must build a model of your design using the materials provided. A Mindstorms program that will direct the robot's movements must be created. A cost estimate of the robot's components must be provided. All revisions to the original design must be recorded and explained. This includes technical design drawings, as well as cost estimates. All revisions to the Mindstorms program must be recorded and explained.

The SRR must be able to move autonomously over a pre-selected route, retrieve the power supply module Zarya, and returning them to the space shuttle (start point). Students are allowed to assist their robot in retrieval of Zarya, as long as a part of the robot is overhanging the tile where Zarya can be found at the start of the simulation. For extra credit, the robot may retrieve specific modules that have fallen off the ISS. The robot must fit in a start area that is 25cm long by 25cm wide. There is no height restriction. These specifications must be met for final commissioning.

Projectile (catapult, slingshot) designs are not allowed.

The robot program may not be altered or switched during any part of the mission. Likewise, the robot must be fully autonomous, and therefore cannot be touched by any person during testing. Please refer to the course syllabus for all due dates.

The robot must return to the space shuttle for the robot to successfully complete the project.

Note: Any student who attempts to alter the course in any way, shape, or fashion (this includes lifting a tile to inspect its design) must meet with the Course Director to explain your attempt at academic dishonesty.

Route Choices

The starting point is indicated by the tile in Figure 1.

Extra Credit

Extra credit is awarded to students who build a robot that retrieves modules back to the space shuttle. The point breakdown for any extra credit is outlined in the EG1003 Grading Policy.

Extra credit will also be awarded if you traverse the "Solar Panel" after pushing the button.

If you would like to design your own route, you may ask your instructor for permission.

Creativity and innovation are always rewarded. Original designs will receive extra credit.

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 LEGO Digital Designer (LDD). LDD can be installed for free from the LEGO website.

Using LDD, 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. If the robot does not use any gears, make sure to explicitly state that in your presentations.

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

Model

The following materials will be provided:

1. Mindstorms kit
2. One NXT/EV3
3. Sensors
4. Motors

The finished SRR must fit within the start tile which is 25cm long by 25cm wide. Any other components that the SRR uses must also fit within the tile.

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 LEGO parts for robot projects.

Note: You should only use the materials contained in the price list for LEGO parts for robot projects. If you want to use other parts, get permission from your faculty member to do so, and also to determine the cost of the parts you want to use that are not in this price list.

The cost estimate should include the following:

• Labor cost breakdown with hours and rates
• Consolidate low-cost pieces: axles, beams, bricks, bushings, connectors, gears, plates
• Itemize high-cost pieces: controllers (EV3 brick), sensors, motors
• No decimal places; this is an estimate after all. Round appropriately
• Total cost must be shown in the bottom right corner

Notebook/Project Journal

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, you must submit your notebook in .pdf format to the EG1004 website, as well as show your notebook to the Open Lab TA completing your assessment. A guide to writing the notebook, as well as a basic overview of its expectations, can be found here.

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.

Late Submission

Late submission is not allowed. If a project does not Commission or receive Partial Commission by the deadline set forth in the syllabus, the project will not be allowed to submit and will receive a 0 for the project grade. To receive Partial Commissioning, two TAs must evaluate the project and determine its degree of completion according to the Commissioning requirements and the project will be given a grade accordingly. Please refer to the EG1004 Grading Policy for more information.
