Robot Design Proposal for Lunar Lord’s JAWR-BOT
CHOOSE US FOR OUR TEAM!
If I were you, I’d choose Lunar Lords for your robot competition. The most important part of any project is getting the right people. We are the right people for Moonbots. We are hard working kids who can focus and work together to get a job done. We are uniquely positioned with a blend of creativity, math-smarts, determination, an interest in science, and of course a love for Legos. Our team leader, Andrew, who is both an inventor and a musician, has pulled together a brand new team. William, an NXT enthusiast, brings critical thinking skills and insightful engineering. He is also our artistic director. Jack, our human calculator, also contributes excellent communication skills, problem solving skills and enthusiasm. Rose brings a strong record of scientific achievements and playfully heads up our creativity and outreach departments. She brings with her the discipline and focus she has learned in her professional ballet training to keep us on track, on time and on budget.
CHOOSE US FOR OUR ROBOT-JAWR-BOT!
Being new to robotics, our focus is on simplicity, reliability and flexibility. We are using a proven four-wheel chassis design (instead of our more elaborate leap-frog mechanism or hexagon rover). Our testing with treads showed that although they were very efficient in getting over obstacles, they caused slipping which complicated navigation, especially if there was loose debris on the field. JAWR_BOT’s reliable 4 wheeler uses two motors for a quadrasteer drive mechanism giving it a tight turning radius. We have two upgrade options. JAWR_BOT can have an optional outrigger canoe feature which helps with balance in rough terrain. It can also have an articulated 6 wheel feature that we will use if the obstacles are placed close together.
JAWR_BOT uses a crane arm for retrieving the H2O and He3. It has the advantage of reaching over and down into craters. If the size of the craters this year makes the crane impractical, we have left ourselves the flexibility of using a non-linear scissor arm option with a smooth capture and release. Both options efficiently run on one motor. The crane starts in the upright position to fit in the space and the scissor option retracts to size. We explored a rotating hook option, but found it was not flexible enough for varied conditions.
In order to improve accuracy while preserving speed we are combining the power of three different navigational tools, the gyro, EOPD and the touch sensors (to use the wall for recalibration.) We are avoiding the compass sensor because a compass would not work on the moon. We are optimizing for speed by using short monitoring cycles.
