 There's a stark difference between bragging and taking pride in your work. While "Ha ha! We're better than you! We won seventeen regionals and you didn't!" would clearly fall in the former, listing your achievements would definitely fall in the latter. - artdutra04 [more] |

at the scrimmage at swamp's on Saturday, we took note on little tweaks that needed to be addressed. here you can see our little improvements, including our spoiler.
Well actually we needed something to protect our electronics from robots and ball we did. when we finished, stepped back to look at it, we noticed that we had also put a spoiler. we killed to birds with stone, protected our 'bot from balls and robots as well as adding an aesthetically pleasing aspect to it. it certainly gives an Indy car look to it. wait until you see it in action.

GENERAL
2-speed transmission (mechanical shift)
4x6 wheel drive
Weight: 120lbs
Measurements: 27 wide x 37¾ long x 28¼ high
Ball capacity: 18 balls
Center of gravity low and centered with respect to the robot
TORQUE:
LOW GEAR/STALL: 137.3 ft-lbs
LOW GEAR/MAX POWER: 68.67 ft-lbs
HIGH GEAR/STALL: 54.92 ft-lbs
HIGH GEAR/MAX POWER: 27.47 ft-lbs
HORSEPOWER:
LOW GEAR @ 2655 RPM: 34.7 hp
HIGH GEAR @ 2655 RPM: 13.88 hp
SPEED:
LOW GEAR @ 5000 RPM: 4.54 ft/sec
HIGH GEAR @ 5000 RPM: 11.3 ft/sec
SENSORS:
Photoelectric sensor tells RC when robot is close enough to wall to release balls. In autonomous mode, robot knows to release balls, during human operation, lights illuminate on the Operator Interface to indicate to the operator that the robot is close enough to release the balls into the goal.
The Allen Bradley photoelectric sensors detect when a ball crosses its path, this sends a signal to the RC which then activates the rollers of the ball pick up system to spin. This allows for optimum battery conservation and effective ball retrieval.

To be completely honest, you guys are insane. I do mean that in the best way possible, but you practically broke our goal! 
Here's a screen-cap:

Can't wait to see the carnage you guys dish out at UCF!

And for your "max power" numbers, since when is power measured in ft-lbs. Where is the unit of time?

Okay, my mistake for misreading your table. But I still don't understand how even cumulatively all the robots in one match could put out 34 horsepower.

hp = 68.37ft-lbs * 2655 RPM / 5252 = 34.56
