About Us

The Mad Rockers of Team 2973 are a proud representation of the impact of engineering in the Madison City Schools System. Combining the two high schools in the Madison City region (Bob Jones and James Clemens), our team works to implement the critical thinking and engineering skills required to be successful in the fields of science, engineering, and technology. With the help of our generous sponsors, caring mentors, encouraging schools, and eager students, we hope to spread the values of FIRST within our community.

About Our Robot:

Recycle Rush – 2015

Our vision processing is much like last years, consisting of small webcams, PCduinos, and written in Python, but our tracking now includes this years game pieces. It consists of matching pixel colors and doing its best job to find the geometry of the bins on the field.

This year, we have a whole new approach to our software, specifically for our driver station. For several years we have had the normal driver station off of our laptop, right next to the driver and operators, but we realized something funny, no one ever looks at the screen! Everyone’s eyes are always locked on the robot, so this year we have developed a system to convey information in a simplistic, visible, and communicative way through a system of LEDs and micro processors. Our robot is equipped with two sets of two custom PCBs, kindly supplied by our sponsor: Advanced Circuits. One set of PCBs is a circular board that brightly displays data, like how much power is being driver through our motors and its own direction, straight from the PWM circuits. The other set of PCBs, is a straight board with 15 LEDs that display information such as successful alignments being driven through our new vision processing software.

Be prepared to see the MadRockers and our robot at the Peach Tree and Bayou regionals.

Aerial Assist – 2014

For 2014 the team set goals to do three things: drive, throw over the truss, and throw into the goal. Miraculously, through the hard work and intelligence of the team we are able to do all three.

To drive we used the chassis from the Andy Mark kit of parts. Everything is from the kit other than our new gears so we can drive at a faster gear ratio.

To set up for our throws we two cameras running tracking software written in Python, powered by two PCduinos. With our tracking possibilities we can accurately determine our and other object’s positions, we can track: the goal (and determine if it is hot), the truss, the ball game piece, and other robot’s bumpers.

To throw, our robot is attached with two of what we call grabbers and an arm. Once aligned to pick up the game piece, the grabbers surround the ball then use pneumatics to enclose onto the ball. Once it has hold, two van door motors, from FIRST choice, lift the ball over head into the arm and cock the the self-contained springs. Along with the self-contained springs we are using latex bands so we can easily adjust the throwing force. When fully cocked a limit switch will be activated, stopping the motors from continuing. In the cocked position we can drive and adjust our shot, then the grabbers are driven forward and out of the way which then trigger the arm, catapulting the arm forward.

Weighing in at 100lbs our 2014 robot will be highly competitive at our two regionals, consisting of the Smoky Mountains Regional in Knoxville, Tennessee and the Bayou in Kenner, Louisiana.
