This page houses the current RoboCup Mechanical efforts. The 2007 efforts can be found here. All development work will be done in Autodesk Inventor 2008. How to use Inventor and get it can be found on the Inventor How to Guide. Inventor is also available on our CAD Machines in Tin.
Mechanical team meets Monday at 7pm and after the general meeting on Thursdays at 6:30

Testing
Dribbler test
Trap ball
- Ball speed- speed the ball can hit the without moving back. Use a spring and a speed trap to measure the speed.
- Ball angle- rotate the robot
- Rebound- distance the ball bounces back
Hold ball
- Center time- measure time in seconds
- Climb ball- measure change in normal force on the measuring platform
- Pull force- angle of loss of contact. Measure what incline the measuring platform is required for the dribbler to lose contact
- Reverse speed- have the robot on a treadmill and measure when the ball comes lose
- Lateral speed- have the robot on the treadmill but have the dribbler facing tangential to the motion
- Rotational speed- rotate the speed of the carpet and see when the dribbler loses control
Material
- Measure either the lifetime of the dribbler under continuous operation and visually inspect the dribbler.
Kicker
- Control speed- speed trap measuring velocity versus voltage
- Accuracy- impact test to measure where the ball impacts a wall
- Lifetime- how long does the kicker last both with a ball being hit and when there is no ball. Also measure changes in speed and accuracy over time.
- Frequency- how long between successive firings
Chipper
- Range- to where the ball lands
- Angle- accuracy to how close the ball lands
- Lifetime analysis same as kicker
Shell impact
- Maximum speed ball at different areas of the shell until it breaks
Omni wheels
- Traction- run the robot up an incline
Useful Links
- Cornell Documents (Look at 2003)
