Agenda
- Each sub team should review the web site http://sites.google.com/site/first1795 and browse the links Mr. Ayers added over the weekend.
- Try to learn about each of the topics, and formulate an opinion about them.
- Each sub-team should continue to work on a short (5 minute) presentation for Wednesday, "What this sub-team wants to accomplish in the 2011 build season"
- Specific hands-on tasks for each team to perform are given below:
- Chassis
- Look through the 80/20 catalog and look through the examples (starting on p23.)
- Draw a parts list for how you would re-implement the kit of parts chassis design using the 80/20 10 series. Tell me how much aluminum extrusion you would need and how many of each fastener.
- Read the catalog fastening options. Which fastening methods would you use for each connection to make in the frame:
- anchor connector
- end connector
- plate
- angle connector
- Try and justify your answer.
- Go into the robot room and collect all of the 80/20 bolts, nuts, extrusions, and other fasteners into one box. They were used on a robot 3 or 4 years ago and are scattered throughout different containers in the room.
- Drivetrain
- Come up with at least 3 rough designs for a 4 wheel drive system with 4 motors. Sketch each one out.
- Sketch a more detailed design for one using gears and gearboxes from AndyMark. Make sure you consider these points:
- Can the chain be removed without taking apart the robot?
- How will you tension the chain?
- Would you prefer 2 motors to work together or for motors to power each wheel independently?
- Appendage
- Thumb through the 80/20 catalog and look at the extrusions and different linear motion options (bearings and rollers)
- Do a charette (a short design exercise) to design an appendage:
- Grab an empty plastic tub from the workshop.
- Assuming the maximum height of the robot is 4 feet, Come up with at least 3 rough designs for an arm that could lift that box 7 feet in the air.
- Sketch all three designs on paper
- What would we use to power the appendage?
- Pneumatics?
- Electric motors?
- Justify your decision.
- Pick one design and make drawings to construct it out of the 80/20 10 series parts (use the catalog). Include dimensions and a list of parts you would need from the catalog and parts we would have to acquire somewhere else.
- Field and Pit
- Crate Design
- I would like for the team to build a new crate this year - one that is easier to open and one we will be proud of to paint and decorate.
- Watch the video for assembling a crate from Team 246: Overclocked http://www.youtube.com/watch?v=39REvO7zR-g
- Assemble a list of materials you would need to build the crate in the video. Make sure you get the thickness for pieces of wood - there is a huge difference between 3/4" plywood and 1/8" plywood!
- Do we already have any of those materials (e.g. the old crate)? Go look in the workshop to see what we have. You can re-use parts of the old crate and change dimensions if you need to.
- Is this a crate design you would like to build?
- Justify why or why not.
- If you like it, have the list of materials we need to buy. E-mail the list of to Mr. Ayers.
- If you would like to go with a different design, make drawings, including dimensions on graph paper. Come up with a list of materials you think you would need and we will discuss next Wednesday before buying materials.
- Spirit / Scouting / Web
- Google Sites Page
- Make sure everyone working on this sub-team on Monday has edit access to the http://sites.google.com/site/first1795 page. Joseph, Dejarius and Fatima have owner access to add someone (using the share button when they login to http://sites.google.com) Allow them to edit the site
- Each person working on this sub-team should edit the 'resources' page and add their name and any contact info they want to share
- Create a new page and use it to take notes on the logo task below.
- Logo
- Do we already have a logo? I think we have the gear logo...
- We need the logo in at least four forms:
- A digital image for a website and/or banner . Use as much color as you want.
- A one-color design we can use on the banner or paint on the crate (maybe cut a stencil out of posterboard?)
- A design we can put on the robot.
- T-shirt (one or two color design)
- Come up with at least 3 rough designs for a banner that include at a minumim the team number, name, and logo.
- Wiring and Programming
- Continue to work on pneumatics on 2010 robot.
- Go through all of our batteries.
- Each battery needs an Anderson connector
- Each anderson connector should be securely fastened to the terminals
- Terminals and connector should be covered with electrical tape
- Label each battery with a marker or label maker tape NOT to lift by the wires
- Get out the chargers, find a place to plug them in and start charging the batteries
- Find the andymark battery plugs and begin implementing the charged battery protocol on the team page.
- Create a design for a 12V breakout board as described on the subteam page. The idea is so we can easily test a motor , solenoid, or other part that needs power without just touching wires to the battery. Here's what I mean
- Use a main power switch from one of the old robots
- Include a fuse
- Battery should connect with an anderson connector
- There should be several ways to easily hook up power
- terminal strips (screw terminals)
- alligator clips
- whatever you can think of.
- If we don't have enough materials to finish the battery and 12V breakout board, please make a list of materials you need and mail them to Mr. Ayers at the end of the session on Monday.
- How many Anderson connectors?
- Do we need Terminal strips?
- Any wire?
