Revision as of 04:36, 28 January 2010
This page contains a week by week breakdown of what we did.
Contents
Kickoff
Week One (1/10-1/16)
- Sunday - Brainstorming - The team met from noon until 4:30 in an intensive brainstorming session. We went through the rules, talked about over all game strategy like "Don't get penalties", and came up with specific strategies for each zone for both Autonomous and Teleop.
- We then broke into two groups to discuss and brainstorm different drive base systems. We talked about the pros and cons of 4WD, 6WD, Mecanum, Pivot and even a tumbler drive. At the end of the session we were leaning towards 6WD and Pivot drive systems
- We then split again to discuss shooters and herders along with how to suspend the robot from the towers. We came up with a number of ideas that we will discuss on Monday.
- Monday - Drive base decisions - The three hour session was mostly around drive base issues and ideas so we could lock into a drive base decision. To help the discussion we made Paper Dolls of the bumps in the field, 4WD and 6WD with a variety of wheel sizes and a mock up of the tumbler.
- There was lots of good discussion around what could work well and what the problem areas would be. At the end we decided to move forward with the pivot drive base. Clem is going to look at what the gearing will look like for 6" and 8" wheels.
- We also got a demo of Google Sketchup a drawing tool that can be used to make quick drawings. We also got to see how SketchyPhysics (a physics plugin for Google Sketchup. It combines a simple and easy to use interface with the power of a fast and accurate physics library) works. It will allow the students to create some interactive (and accurate) models. A small team was started on creating models for:
- Flipper (two flippers that will act like pinball flippers to move the ball.
- Sweeper (Rolling tube with vanes that will roll the ball)
- Kicker (Foot on a leg to kick the ball, along with guide plates)
- Pusher (Flat plate with two pneumatic cylinders)
- Cory Foot - a foot on a rotating arm that extends as it rotates
- Meanwhile, down in the shop, the construction of the bumps started. Matt, Alex and Faith got things underway by getting the first few sheets of plywood cut. The goal is to have all field components complete by the 19th.
- Tuesday - No meeting on Tuesday
- Wednesday - Field Build and more design
- More progress on getting the field components cut out and assembled. The bump is looking good, we can start to see how interesting this will make the game
- Thursday - We have a Bump!
- The bump got completed and the field team started cutting parts for the goal. Kicker prototypes have been drawn in Sketchup/Shetchy Physics and some ideas will move from the simulation to the prototype process.
- Friday - Rest for the weary, no meeting
- Saturday - our first all day build
- Lots of activity with lots of people working is the best description of the day.
- Programming made great progress. After a kick off meeting the team set about doing a number of different projects.
- With the robot still in the design phase the Electrical team is not ready to do any major work. They did some work on testing battery systems and doing some minor repairs.
- The largest amount of progress was made with the Field Components. casters and a large handle were added to the bump to make it super easy to move. The tower supports were completed and a test of some lighter weight pipe showed that we need to use the Schedule 40 pipe (or find lighter roboteers). Progress on the goal continues.
- There were lots of flying soccer balls with the kicker prototypes in full swing.
- Thanks to Anne and Rita for feeding us great pizza with garden salads for lunch along with chicken and Mac/Cheese for dinner. The oranges made a great mid-day snack.
Week Two (1/17-1/23)
- Sunday - Jumping into week two
- We started week two off with a bang with the sounds of balls hitting the wall. All of the teams made good progress towards their goals.
- Accomplishments:
- We've got a pretty good kicker prototype. Made the ball fly (but didn't break any clocks).
- Pivot parts drawings completed for transfer to Machinist.
- Field Equipment is proceeding well. The goal is very big and voluminous
- Programming is moving forward with the vision system.
- Electrical parts have been sorted and reorganized for easy access.
- Thanks to Andrea for homemade meatball sandwiches and pasta salad.
- Monday - moving the ball
- The air spring kicker didn't turn out the way we thought it would
- But the latex tubing kicker is a trooper
- it's all about kicker momentum at the time/point of impact
- the depleted Uranium kicker (Rizzo test) made no difference - heavier kicker is slower to accelerate - hits ball at slower velocity - same momentum - same travel
- The CAD team got a CAD workout
- Field equipment getting close to complete
- Saturday - cutting the frame
- Cut almost all frame elements
- Dry-assembled and tested all steering motors
- More kicker testing and detailed design
- Bumpers started
- The final field element - the tunnel/platform - is finished
Week Three (1/24-1/30)
- Sunday - Welding day
- We've got a chassis frame (excluding gussets). Matt did a great job welding this in a day.
- Steering motors epoxy-bonded to steering drive sprockets w/ encoder magnets
- First magnetic encoder mounted on steering motor and tested. Excellent linearity.
- All chains broken to right lengths
- dxf of Pivot Plate Top completed
- Demonstrated proof-of-concept for line-rider
- Camera working and acquiring target
- Tuesday
- Most of Tuesday was spent in a team meeting going over where we are in the design process and making sure our strategy / plans are on track and understood by everyone on the team.
- Wednesday - full build ahead!
- Had 16 students show up tonight- Brianna, Amanda, Carly, Christine, Selina, Ben R., Nicole,Sasha, Cole, Andrew,Doug, Alex, DJ. Paul, Preveen and Zain.
- Jon worked with programmers, David helped Jon with game stratergy.Praveen ,Sasha, Paul,Ben R., Zain, Nicole,DJ got the inhouse chat working but needs to be put on a server..... Now he will be learning Labview to use it. Paul is making a Labview disc for both DJ and Alex-will be ready tomorrow-Ben R. to help DJ learn Labview.
- Metal cut for bumpers / screws bought to install them-Faith, Doug, Cole
- Kicker mounts marked and cut-Selina & Carly
- Trident built- Julie, Christine,Alex, Amanda Brianna
- Scott and Garry Andrew ,Sasha, Carly started electrical
- Rizzo and Cole fit and marked gusset positions
