2015:Lifter Subteam

General Summary:

Uses Chain to lift car along rail.

Grippers are fixed on car and slide up and down rail.

2013 Design is being used as a reference point for design.

Weight Limit set at integration: 36 Pounds. Current Estimate: 30 Pounds (Integration Weight sheet)

Stabilizing Mechanism must be mounted near the top of the Lifter

Required Specifications:

Gripper Must move to a max height of slightly over 5 feet and as low as 10 inches from the ground (NOT FRAME)

Less than 36 pounds

Able to lift at minimum 41.9 pounds and a maximum of 57.5 Pounds

Keep CG as low as possible

Have a stable mounting position for the second gripper/stabilizer

Guide Rails up too 78 inches (6' 6")

Fast as Possible. (1 level per 2 seconds with load/ 1 Meter/Second)?

Is the Best part on the Robot.
