Robots

 

Team 568 has several robots which include the 2006 and 2007 competition bots. (Mach 6 and Mach 7) In addition to the Mach 6 and 7, we have the former Anchorage Bomb Squad robot which runs on a system of 24v batteries and motors with a 12v FRC control system. We also have another robot that we are working on that can be controlled by anyone in the school who is connected to the school's wifi with a designated, web-based logon.

 

 

 

The charge is signaled...

Team 568's absolute zero races forward toward the light with keeper in hand. As it approaches the rack it slows and creeps forward the last foot... as autonomous period is ending it releases the keeper and ... yes it catches on the rack and makes a score.
ding...ding...ding... drivers take over. Human players begin tossing rings into the field a few feet from the rack. They are tossing them over the 6 foot screen and they land haphazardly, some rolling around before coming flat on the ground. Absolute zero turns quickly and drops the claw to the ground snapping closed on a ringer. Lifting to low level it turns and moves slightly to the left, the omni drive allowing seamless maneuvering. A jog to the right and the ringer is placed... we have two in a row. The copilot records this placement on the dashboard game model, and an updated game strategy appears on the drivers heads-up display...

... The game is rapidly approaching the end game state. The rack has many ringers on it and the teams are swamped by the possibilities... should they place a ringer?..where?...should they head for home?...what about a spoiler?... The drivers sees the spoiler light flash on the dashboard...the display indicated it needs to be placed in middle of the number 4 spider leg.... he starts to go get a spoiler to deal with this task when a bright amber light begins flashing, its the go home light, absolute zero is frantically telling the driver that there is just enough time to get to the home zone and lift some bots....with a zig and a zag zero makes it home with 10 seconds to spare...positioned in the middle of the zone our two alliance robots approach from either side and drive up the ramp...the lift engages and within 5 seconds the bots are 12.1 inches off the field....
buzzzzzzzzzz.....game over

Did we win? What happened...

 

 

 

 

Absolute Zero Mach 7 is powered by a 2-wheel omni drive system, which will allow all 2 wheels to spin 180 degrees allowing for maximum maneuverability during the game. Each wheel will be locked into position with a disc braking system powered by pneumatics. Absolute Zero will also have a large 44" ramp that the other bots will drive up during the end game. Then, once the second bot is on the ramp, the pneumatics at the end of the ramp will extend, thus lifting the second bot 12" off the ground. It also has a two stage arm that can extend to the second spider, and achieves its lift with a pulley system. The claw is powered by a small pneumatic ram to close onto the ringers. For decoration, we also created an outline of the Anchorage moutainscape out of sheet metal.

Mach 7 is constructed primarily of 8020 and 8030 Bosch aluminum, and has an on-board compressor with 4-air tanks for the various pneumatics on the robot. We also have clear lexan covering the sides and top for protection and easy access. Mach 7 also has a CMU camera that is mounted to it for the autonomous period where the robot will attempt to score on its own programming.

 

 

 

 

Absolute Zero Mach 6 is Team 568's 2006 FRC robot which proved itself a worthy adversary for any team at the Davis-Sacrameto Regional in 2006.

 

 

The primary material for Absolute Zero Mach 6 is 8020 aluminum Bosch, as well as the IFI standard chassis, which is the basis for a 4-wheel drive drivetrain. The drivetrain consists of two drive motors and two gearboxes, which are, connected to the front a rear wheels via a chain drive system.

Absolute Zero uses a system of two drive motors connected to rubber tires for the ball launcher, and the robot can be aimed via the CMU camera.

The bot cannot pick up balls however, and relies on the human players ability to throw balls into the top of the robot, which then roll down the 'tube' to the launcher. Once at the bottom, a rod then 'kicks' the balls into the launcher so that we can control when we want to fire. It can also fire at a very fast rate; it can fire the next ball as soon as the first one hits the launch wheels.
