Design 1:
As our original group design, this AEV combined balance and stability to produce an equally efficient design in which the design is symmetrical and the motors are on opposite sides, however, this design lacks a spot for the caboose to connect to.
Design 2:
This design is a revision of the first design in the sense that one motor is lowered to allow a spot for the caboose to connect to. The downside of this lengthy design is that it tends to sway back and forth along the z-axis.
Design 3:
This design is a revision to Design 2 in which it uses a horizontal design instead of a vertical design to get rid of the sway along the z-axis. The motors are oriented the same on this design as they are on design 2.
Design 4:
This design is a revision to Design 3 in which it gets rid of one motor and centers the arm to create an extremely lightweight, balanced, and streamline design that maximizes efficiency by only using one motor instead of two. The problem with this design is that it does not produce enough power to move the AEV and Caboose.
Design 5 (Final Design):
This design is a revision to Design 4 in which the motor is moved to the other side so that when the AEV connects to the Caboose, the motor is in the center of mass of both the AEV and Caboose which makes it easier for the motor to move the system. This final design is able to move the AEV and Caboose and it is an extremely lightweight, balanced, streamline, and cheap design that Team R used to complete their Final Run.
