Brainstorm session: Possible topologies for positioning:



1: extendable arm
+ : pole coordinates
    static motors
    grouping of the motors -> compact design
- : obstruction by rear end of arm
    linear movement (solvable)
    moving cables

2: double arm
+ : flexible positioning
    possibility for multiple paths
- : dependency motor 1 of motor 2 for positioning

3: guided crane
+ : x-y coordinates
- : drag on guidance / weight compensation / double motors
    big set up
    moving cables

4: crane
+ : flexible positioning
    looks cool
- : extra motor required + 3d dependencies

5: car
+ : super flexible
- : feedback on positioning required
    driving on the work plane

Brainstorm session: Possible topologies for positioning:



+ : length arm 1 < length arm 2 < length arm 3
- : 1 requires extra material for a suspension mechanism
