for ME/PDM/Aero undergrads the tolerance is +/- 0.005"
for EE/CE/Physics undergrads the tolerance is +/- 0.015"
face the end of the rod
create a drawing of the part. Only two views are needed because of the symmetry
other - TBD
Detailed design - Phase I
Based on teams and projects
September 29 - Turning and Project Work
Laboratory:

7:45 pm - As a group
Teams - present findings from research
All - select design problems and teams
All - review parts of the NDA
Intro - agreement to agree
Sec 1 - A definition of what is considered secret
Sec 2 - You or your people cannot share the secrets
Sec 3 - Pre-agreement knowledge is not secret
Sec 4 - The secret is owned, as in property
Sec 5 - The agreement does not give property rights
Sec 6 - The reason for the agreement is secret
Sec 7 - Get new secrets for 1 year, keep secrets for 5
Sec 8 - New agreements cannot replace this one
Sec 9 - Only and all legal stuff is allowed or enforced

Teams - competition teamwork
Assigned:
Design Project - each design team (or individual) will submit 5 viable alternatives/concepts to solve the design problem. These need to include suitable documentation (sketches, block diagrams, APIs, GUIs, user models, etc.) Where needed proof of concept calculations are also required.
Chapter 5 - Joining
Competition Rules Draft Version
1. The robots will work in a field surrounded by wooden walls. The approximate dimensions will be 6-8 ft on each side.
2. Each team will start touching opposing walls. The starting location will be a boxed volume 2ft wide at the center of the wall, 10 inches deep, and 8 inches high.
3. The objective is to have any of the robots reach the opposing wall as fast as possible.
4. If neither team is able to reach the farthest wall then the closest distance to the wall will be used to select a winner. The time and distance are at the discretion of the judge.
5. Damage to opposing robots may result in disqualification. Note: no destructive strategies.
6. The teams may add materials or modify the robots but can only use electronic components found in the Boebot kits, or equivalent replacements.
7. The competition will be run in multiple rounds. In each round all of the teams will take turns competing against all others. Each round the bottom two teams will be eliminated.
September 22 - Prototype Design Review and Milling Introduction
Laboratory:
Machined parts due with drawings
Competition
Review of selected design problems by each team.
Start of brainstorming for solutions
Assigned:
Investigate and research concepts for the 5 problems
What is (or has been) on the market?
What are the competitive technologies or solutions?
Are there any patents that apply?
What are the potential markets?
If there are solutions what are the shortcomings?
Note: If you find solutions investigate them.
September 15 - Milling
Laboratory:
Manual mill qualification done by 7:45pm
Demonstrate completed Boebot
Present list of problems
Begin robot team project
Assign teams
Select Competition
Assigned:
Individuals review the NDA (signed before) and list the fundamental parts on your web page.
Typically each paragraph of the agreement contains a major idea such as 'only share secrets with permission'.
Individuals complete the milled/drilled/tapped parts with drawings for submission.
Teams are to review the list of problems
- Select 5 that have potential for inventions (do not consider the solutions yet).
- Problems with viable commercial solutions should be eliminated unless there is a major shortcoming of the current solution.
- Look for problems that pose a major problem, impact a large number of people, or that do not have any good solutions.
- A crude but effective selection tool is to consider what people are willing to pay for.
Teams Prepare the robots for competition round 1.
The course will be a path of PVC electrical tape 10 to 30 ft in length with curves
The team will set all four robots down in a sequence behind a starting line
The time will start when the first robot crosses the start line. The time will end when the first robot crosses the finish line.
Each robot after the first that crosses the line will subtract 20 seconds from the time.
Robots that leave the line are immediately disqualified
