Epic Design Rational


Four wheel drive to navigate barrier and craters.  Optional, hyperaccurate two wheel drive mode for precision turns (see video and pictures).

Arm with wheels to gather Helium 3 and Water as well as two wheel drive mode stabilization.



Sensors

HiTechnic Accelereration Sensor;

How we would use the accelerometer for our robot, EPIC: 

Like the accelerometer in the new smart phones that allows the screen to rotate horizontally and vertically, the accelerometer sensor for our robot would be helpful to sense when the robot is traveling on its main set of wheels or flipped its side traveling on the secondary set of wheels.  Used for tracking position on three axis relative to start position.  This will assist with standard four wheel drive mode verses hyperaccurate two wheel vertical drive mode (see pictures and video).  Also used for positional navigation over obstacles.


HiTechnic Gyro Sensor;

Used to track rotation off of the single axis gyro for turning accuracy


High Technic EOPS Sensor;

The Electro Optical Proximity Detector will be used for targeting craters, Helium 3 and Water. 


NXT Ultra Sonic Sensor;

Used to track along walls to help navigate the great circle route that we will use in the mission plan.  Will also help identify distance to target for Helium 3 and Water.


Camera

Mega Mini Spy Camera Pro

 Small battery operated miniature camcorder with built in DVR to record mission from robot perspective.  It is the size of a pack of gum.





Here is the arm attachment for our robot spacecraft “EPIC”.  It would work by extending from the robot base to “ring” (hook and ring action)  the helium 3 elements and carrying them back to base.  There is enough space and room to carry all 10 of the ring elements. It could be used either in this position or in the upside down reverse position.    Even though the orientation of the ring elements could be different we could program our robot to accurately turn to each individual ring’s orientation.  One aspect of this attachment is that the rings will stay in place while traveling over the bumpy surface of the moon.   We have used a similar attachment in the FLL challenge mission to “hook and ring” the corn rings in the power puzzle challenge, and the red and gray loops of the smart move challenge.
