2012:Robot Design Details
Preliminary Design
Preliminary design after Sunday January 8th Design Sessions
-Drivetrain - 6 Wheel Pnuematic
-Collectors to prototype
-Stationary Beater Bar -Actuator Beater Bar and Wings -Hungry Hungry Hippos -U Shaped Brush
-Bridge Actuators to prototype
-Actuator also acts as collector -actuator is seperate from collector
-Storage will be 3 stage
-Shooter will be a turret
-Spinning wheels to shoot -Need backspin on ball -Variable Speed -Variable angle (could be speed) -Need to shoot over 60ft.
Robot Specifications
Overall:
• Time from collection to shooting should be less than 2 seconds.
• The direction that the balls leave the robot must be opposite from the side of the robot that collects the balls.
• All designs need to be robust so that time spent fixing the robot is to a minimum.
• All parts should be easily serviced if needed.
Shooter:
• Must be consistent within 2 degrees of the hoop when shooting from the key.
• Range must be from at least the barrier of the far zone to the basket.
• Must be able to shoot over 60 inch obstacles.
• Desired to have a design conducive to a automated aiming system.
• Time between command to fire and ball firing must be less than 0.5 seconds.
Storage:
• Must have ability to queue balls to get them ready to fire as soon as possible.
• Must have sensors to detect ball movement through the system.
• Must be able to remove balls from the system when the robot is turned off.
• Speed of transit must satisfy combined collection to shoot time of 2 seconds.
Collector:
• Must be able to be turned off and on quickly.
• Must be able to pick up balls that are located on the wall of the court easily.
• Must be able to pick up a ball when in contact with the collector and immediately (<0.2 seconds) pass it to the storage system.
Bridge Articulator:
• Must be able to exert enough force to lower the bridge to the point where the drive train can easily get on the bridge.
• Needs to be able to take the abuse of another robot or force resisting the motion of putting down the bridge.
• Must be able to manipulate the bridge from horizontal to drive over position in less than 1 second.
• It would also be useful to have the articulator assist in ball collection.
Drivetrain:
• Must be able to easily transverse the barrier and bridges in less than 2 seconds.
• Max Drivetrain speed should be between 10 to 11ft/s.
• Drivetrain must have slow mode for fine control on bridges and barriers.
