Esa playa, our most successful robot so far, was named “Esa Playa” after an inside joke between the club members.  It is a six wheel tank drive powered by two SIM motors, accommodating two motors for each of the two sides that allow Esa Playa to shift when desired.  Due to this year’s game, two additional motors were were attached to the front of the robot, serving as intake and outtake mechanisms to retrieve and release the boulder during the matches.  The intake/ outtake mechanisms allowed for the team to score goals, whether they were low or high goals thanks to the arms the motors are attached to that can move at any angle from zero to more than 100 degrees.   In addition, the red acrylic wedges that are present on either side of the shooting arms also us to go through a defense we otherwise may not have been able to go through.  Esa Playa may not be the most attractive robot around, however, it is the BOULDEST one you will encounter due to its ability to work as an offensive or defensive robot.

Named after our former mentor, Chance Carpenter, this robot was our solution to the problem presented by Recycle Rush.  Our robot used a chain driven elevator with 5 hooks to pick up individual totes in stacks.  It also had a separate system, a  winch-driven elevator that allowed us to stack trash cans on top of the totes.  Chance Danger also featured a suspension system and mecanum wheels in order to allow it to go over the raised scoring platform easily and maneuver through stacks of boxes without issue.  In order to intake totes, our robot had 2 wedge shaped intakes with several powered wheels in order to drive apart totes in the landfill and intake them individually before stacking them.  The motors could also be reversed, so that the wheels pushed out a stack of totes, allowing us to disengage better when depositing stacks on the scoring platform.

Competition – Aerial Assist (2014)

Taking its name from its signature grabber system and a coincidental Del Taco bag left on a shop table, Del Toro is team 4619’s response to the 2014 Aerial Assist competition challenge. Prioritizing maneuverability over strength, a CIM motor on each of the four mecanum wheels provide the ability to not only drive traditionally, but allow side-to-side “strafing” through the wheels’ clever design. Two counter-rotating PVC pipes, wrapped in grip tape, and an inward-pulling elastic band provide a grabber mechanism that pulls the ball into the body of the robot. To start within the boundaries required by the competition, these grabbers flip to an upright position, then flip backwards and lock into place with a simple spring lock. Del Toro’s launching mechanism is a mechanically driven catapult, powered by two CIM motors and a gear-and-chain system that connects the motors to a shaft that rotates a pair of aluminum arms. With different launch strengths programmed, the robot is capable of launching the ball from various positions on the field. Also notable on our robot is the decision to mount many of our electronics vertically on the inner front panel to save space where the ball sits in our robot – the electronics are protected from the front with a metal grill.

Github Page for this robot’s code.



As the first robot this team has ever built, Chassidy is no work of art, but when it comes to competition time it definitely gets the job done. Chassidy is built on a strong six wheel tank drive, powered by two CIM motors mounted on an aluminum drive train frame. Mounted on the robot is a framework made from bars of 80/20 aluminum, which supports a fixed two layer frisbee launching platform. The launcher’s top layer is a simple slide where frisbees can be loaded onto the robot through the loading slots – the frisbee then falls to the lower layer, where a flipper pushes the frisbee into a pair of high RPM wheels that launch the frisbee. The launcher is set at an angle for both frisbee loading from the loading slots and for high goal shots from a certain spot on the field, right next to the pyramid structure.
