REASON FOR CONTACT: Current Progress
MAIN POINTS OF CONTACT:
1. Discussion of whether or not current product is a probot 2.
2. Discussion of soil tray appearance
3. Discussion of the difference between soil-samples, sand dunes, and sediment,
and what the sampler has to do
and what the sampler has to do

TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: General Request for assistance
MAIN POINTS OF CONTACT:
1. Sending of useful VEX robotics websites and forums
2. Discussion of current progress
DATE OF CONTACT: 02/09/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Discussion of DOF
MAIN POINTS OF CONTACT:
1. DOF = Degrees of Freedom = how many joints.
2. 1 DOF arm goes up and down
2 DOF arm goes up and down, plus wrist turns?
2 DOF arm goes up and down, also side to side.

3. If a "sample tray" was just a basket on the top of your robot hull,
and if "taking a soil sample" was just "pick up a 1" square wood block with a claw"
then all you need is
- an arm with a claw,
-- that can reach the ground in front of robot,
-- and also lift up high and over head to drop the block upside down in the basket.
Thats just 1 DOF needed, from down in front to overhead on back.

DATE OF CONTACT: 02/14/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Discussion of arm
MAIN POINTS OF CONTACT:
1. Comparing scoop method and other alternatives for claw
2. Discussion of how much soil the tray would be able to hold
3. Possibility of have some kind of carousel in the back that spins when you want to dump the sample into a different compartment.
MENTOR NAME: RoboDesigners, DiodeTech, jgraber, TomW, whatbricks,
DATE OF CONTACT: 02/15/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Posting of video of current robot status to forum and following discussion.
MAIN POINTS OF CONTACT:
1. Discussion of robot
2. What partner and I did to get to this point
3. How to progress further
4. Material list
DATE OF CONTACT: 02/15/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Discussion of bearing flats
MAIN POINTS OF DISCUSSION:
1. Use of bearing flats=crucial
2. Placement of said bearing flats on two axles of arm
3. Arm should be on shorter axles to prevent the axle from bending or there could be a support in the middle.
4. Helpfulness of putting 2 lock collars on the axle on the insides or outsides of the supports to keep the axles from sliding around.
5. Request for a sketch of what arm is to look like
DATE OF CONTACT: 02/16/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Discussion of Claw
MAIN POINTS OF DISCUSSION:
1. Discussion of bulldozer-type robot
2. Sending of pictures of possible robot apparatus
3. Comparison of NASA claws
DATE OF CONTACT: 02/16/2012
TYPE OF CONTACT: Online VEX Robotics Forum
REASON FOR CONTACT: Creation of basic arm
MAIN POINTS FOR DISCUSSION:
1. Secure of piece of metal to the top gear in the video. If you look at the top gear, there are two holes that you can put screws through and then use a nut to secure the metal to the gear
2. use a smaller gear for the bottom, preferable the smallest type because that gear ratio you have right now is probably not strong enough for your purposes
3. use of delrin bearings if possible to make sure axles don't bend.
