So its time for the annual reveal of the robot that my team and I have worked on throughout the summer. Many teams have talked about the inhale the wall (of game objects) as a possibly unbeatable strategy, and my team is hoping that this is correct.
The features we built this robot to have:
–Can pick up all 18 game objects in the center of the gateway field
–Can score the game objects in goals of any height
–Can shuffle game objects while driving between goals
Motor and pneumatic distribution:
Four HS motors internally geared for torque - one per wheel
Two motors of the strafe part of the H-drive
Two motors on the lift
Two motors on tank tread
Two double acting pneumatic pistons to tilt the large bucket
Finally the pictures. Click on the thumbnail for more detail: Its a good way to show pictures without making the page take forever to load.
–Bevel gear system on the front wheels saved a lot of horizontal space and worked surprisingly well under a lot of weight.
–The robot unfolded because of latex pulling on a winch system, which would keep the robot’s chassis unfolded.
–The pneumatic pistons had a TON of elastic helping to lift the bucket. Each time the pneumatics would fire, the game objects would fly into the air. This was how we would funnel game objects to the tank tread system and combining the two systems, we could shuffle objects while we drove between goals or played defense, until we had only objects of our color in the tank-tread.
In the end, we ended up completely disassembling the robot because of its lack of consistency. At times the robot was unbeatable, but often after a lot of use, it would start to fail. My team decided that we needed a more stable robot, with a more robust drivetrain, that would require less work to maintain.
This robot only went to one competition in Connecticut, where it performed well in the qualifications finishing as the second seed. However in the eliminations we lost in the first round when we were disqualified in one match (The robot drove off the square as I was putting match loads in. My fault.) We won the second match, and in the third match, our alliance partner had a bad battery and our robot performed poorly.
Questions and comments are appreciated.
