This stuff is obvious to most people, but I made this to hand to rookies before they start giving me wild and unpractical designs on monday. It's a draft, so I'm open to suggestions on it.

Attached to this post is the same outline, except it is in a word document and properly formatted.

Criteria for tetra manipulators

1) RELIABILITY
a) Ease of use
i) Driver
ii) Human player
b) Dropping
i) Properly picking up
ii) Properly moving
c) Capping
i) Bump resistance
ii) Able to cap at any angle
d) Mechanical failure
e) Simplicity
2) VERSATILITY
a) Short goals
b) Autonomous mode
i) Hanging tetras
ii) Vision tetras
c) Loading stations
i) Human player stations
ii) Automatic loading stations
d) High goals
e) Stacks
i) Making stacks
ii) Covering stacks
3) SPEED
a) Grabbing speed
b) Capping speed

Other desirable features:
1) The ability to correct the robot after tipping.
2) A low center of gravity to prevent tipping
3) Low weight
4) Quickly serviceable

1) RELIABILITY
a) Ease of use
i) Driver
ii) Human player
b) Dropping
i) The tetra must be held tight from the moment it is grabbed, to the moment it is released
c) Capping
i) Bump resistance
ii) Able to cap at any angle
2) VERSATILITY
a) Short goals
b) Vision tetras
c) Human player tetras
d) High goals
e) Stacks

3) SPEED

b) Capping speed


Remember to design with autonomus in mind! What's easy for a driver to use may not be easy to program for...

I agree autonomus mode is very important to the arm design otherwise you severly limit your autonomous options later on

I took your suggestions and updated the post above. I also added a few more things. Again, this is mostly basic stuff (low center of gravity, light weight, etc), but hopefully it will help some of the rookies in the team generate ideas.
