2009 Robot photo

Dimensions:27″W x 36″L x 58″H
Weight:110 lbs
Concept:Early on in the design process, our team recognized two general design approaches to the 2009 Challenge: A “dumper” that could unload a large number of balls quickly, but only in one direction, or a “turreted shooter” capable of scoring at various angles, but would be slower and potentially less accurate.

Our final design was a hybrid of the two; we combined the throughput of the dumper with the flexibility of the turret. The end result was a robot that could score within a 180-degree arc from the front of the robot, and do this at 7 balls/second.

  • Custom single-speed transmission
  • Four-wheel tank drive
  • Modular design
  • Large hopper
  • Pickup balls from the ground
  • Shoots up to 7 balls/sec.
  • Automatic camera tracking enabled
  • Able to score autonomously

Weight:120 lbs
Concept:Our team decided that the ability to go over the bump would be important in the game. Although going under the tunnel would be difficult (due to the careful alignment involved), we decided to build the robot so that it could drive under the tunnel if we needed to, both as a way to force us to keep the center of gravity low as well as to give us the option of going under the tunnel the one time it may be useful. To maintain maneuverability as well as go over the bump easily, we chose an eight-wheel-drive design.

A surgical tubing powered kicker, reloaded by a pneumatic cylinder, was simple to design and implement, and has less points for failure. It allows us to kick the ball into the goals from almost anywhere on the field.

Finally, because the robot would be very short relative to its weight, we were able to strengthen parts of the robot where, in previous years, we would not have the weight to do so. The result is an extremely robust design.

  • Custom two-speed shift on the fly transmission (8 and 16 feet per second)
  • Extremely robust
  • Very low center of gravity; virtually impossible to tip by itself
  • Ball retention device to possess balls when the robot lines up for a shot
  • Kicker capable of scoring from all three zones
  • Goes over the bump and under the tunnel

Concept:Deciding that scoring on all three levels of the rack would be crucial, our team also noted that the minibot race would change the outcome of many matches. We decided to build a robot which would have the ability to do both using a telescoping arm and a spring powered minibot deployment. By keeping the pivot point for the arm low, we are able to pick up and score on both sides. A roller gripper allows manipulation of the tube while being possessed, preparing for scoring on the rack.
  • Custom two-speed shift on the fly transmission (5 and 13 feet per second)
  • Extremely robust
  • Arm capable of scoring on all three levels
  • Roller gripper can manipulate tubes while in possession
  • Quick deployment of minibot (1 second)
  • Rapid minibot ascension (1 second)

Dimensions:27″W x 36″L x 59″H
Weight:118 lbs
Concept:Our team recognized early on in the season that with the limited number of balls on the field, acquiring balls quickly and making every shot count would be very important. These shots also need to be taken quickly without needing much time to line up, even if the robot is under heavy defense. Furthermore, a low center of gravity was desired for easier bump traversal and bridge balancing. With a full-width pickup, high speed elevator, and a software-automated turret, our robot achieves all these criteria and is able to make close range shots quickly with near 100% accuracy, even under heavy defense.
  • Custom two-speed shift-on-the-fly transmission: 6 and 17 feet per second
  • 8wd “West Coast Drive” base: Light, robust, and easy to maintain
  • Full-width pickup: Easy ball acquisition, doubles as a bridge manipulator
  • Elevator/hopper: ~0.5 second lift to 84″ high, counterbalanced via constant force spring, holds 3 balls, very low center-of-gravity when retracted
  • Turreted shooter: ~0.5 second 360 degree rotation, 2 position hood
  • Software-assisted operation: Automatic pickup and shoot sequences, automated turret aiming, off-board image processing for maximum performance
