DOUBLE ELIMINATION BOTS:

Delphinus- This bot swept the solar arrays and sorted the poms into the potato bin. This robot used its massive claw in front for the sorting and a long chain of liftarms for the sweeping, as well as a mini servo for holding the potato bin.

Durf- This was our most creative bot yet. Durf was an offensive bot that deployed an arm across the game board. This arm prevented the other team from accessing their ramp and potato bin. Durf scored points from knocking botguy over as well as deploying a chassis (Bob) for the windup toy to PVC hop and knock off the opponents potato bin.

Bob- In this picture you can see the last of the DE setup. Bob is the chassis which connects to Durf via servo extension cables. Bob rests on a ramp that’s held up by Delphinus. When Delphinus starts the ramp is dropped deploying Bob, Bob hits the PVC and releases the Windup toy.

SEEDING BOTS:

Little Dipper- This bot here knocked over the green orb on the small section of PVC, then used its arm to lift up the movable section of PVC between both sides of the board. Then Little Dipper stole the other teams potato bin, while sweeping the solar arrays.

Little Buddy- This bot sorted the red and green poms with an advanced camera function. It would find the poms, hit them with its arm and drive back and forth to ensure the poms slipped through the axles staying in the claw. Next the bot would bring its claw back to store the poms in a container made of paper.

SHOWCASE:

This is our showcase bot. This bot jumped without the help of a wallaby.

Milikan-  NARs’ sweeper bot. This bot drove up the ramp and swept the Mars dirt from the solar arrays.

The Denier- This is another one of NARs’ innovations. This bot won a Judges’ choice because of its PVC hopping ability. The bot would knock over the green orb right outside the starting box, hop the PVC and ram into the opponents potato bin.

Sorter bots, climbing mountains, and fierce competition!

BlimpCast

cam00085

Overview
BlimpCast, a project created by NAR members in the summer of 2012, is a autonomous blimp that will stream a aerial view of GCER 2013.  A helium filled blimp supports a Arduino controlled gondola with vectoring propellers and various sensors to navigate autonomously.

 

Versions

Autonomous: A arduino uses four IR sensors to track its heading relative to a ground based IR beacon and a sonar to track altitude. Two propellers can be throttled independently and vectored up and down using a servo. The arduino uses independant throttling to steer the blimp into a circular pattern around the IR beacon, and the vectoring servo to hold altitude.

Radio Controlled: For GCER 2013, the blimp will be carrying a camera that will be streamed online. Due to the limitations of weight and consistency of the autonomous system, a RC gondola will be constructed for use during GCER. It will be capable of being piloted with a RC transmitter or joystick.

 

Progress

The autonomous BlimpCast gondola is almost complete. Motors and IR sensors are completely functional. The servo and Sonar have yet to be connected and tested. The code will be a ported version of Blimpduino code.
