HATCH GRAB MECH

• After much discussion we believe that the tin can grabber/grappling hook/umbrella design should be pursued as the best potential design.

• For visuals look to the cookie monster ri3d and pic steven posted on slack/ other google doc also

LATERAL MOTION

• We have decided to pursue the linear actuator or similar design to the climber subteam so it could move with the precision of a router

FRONTAL MOTION

• The mechanism will be a module which at the beginning of the match would be rotated or pushed in front of the frame perimeter

• Mounted prototype 1, with the hooks, onto Atlas-Z to test whether or not we want a sideways moving mechanism.
• We tested placing the hatch on a cargo-ship-like structure with velcro, and saw that a driver without camera is very innacurate.
• We definitely think we want a camera to align ourselves.
• This test also concluded that we want a sideways moving mechanism. We think we want about 3 inches side to side movement from the center of our mechanism. 
  • we also realized that the heavy part of the mechanism is not going to be the bar but rahter the motor/attachments, so making the bar longer should not be a problem. we can make enough room to extend up to 10" on either side if we really wanted to, it would just make driver alignment easier

testing on atlas-z

• lining up with the cargo ship is tough 
• how much wiggle room do we want??
  • how "deep" into the robot should it be so that it doesn't run into screws for climber

Jobs for Prototype #1 (tabled at the moment, need to move on to other prototypes)

have better test parameters 

Might want to 3D print the parts instead of using the bolts and add some more reinforcement/cushion to the bolts 

We should get some data if there is an angular problem with the drivetrain and if so how much

Other Tasks

start building the grapping hook prototype 
Start designing sideways movement mechanism, figure out how we want to prototype. 
Complete adding designs to the list of designs, including all designs mentioned or talked about on Slack or ones we may have not considered fully yet. After doing so, add pros and cons for each, a sketch, and rank the designs once all are on the list.

Build the practice hatch if it is routed

Record and discuss pros and cons and modify prototype based on testing data (We have pros & cons but now we need to record data for tests for multiple prototypes that we have considered to be our best designs).

If done with the first prototype, sort and rank the remaining designs, and create prototypes for the best.

Test how much wiggle room we have with the velcro and if we will need a sideways elevator mechanism to align better (Which is most likely at this point).

Create a mechanism that is able to set the hatch panel from an angle (individually controlled pistons behind horizontal elevator?)

I think so, but we should try to get the beak working soon
