2015:Gripper 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: 36 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. Progress as of 1/10/2015 (7 Days Used/38 Remaining) Design 10% Complete Summary of 1/10/2015: Rough CAD begun and actuation design concepts complete (CAD pic) Summary of 1/11/2015: Summary of 1/13/2015: Summary of 1/14/2015: Summary of 1/15/2015: Manufature 0% Complete Testing 0% Complete

Detailed Work Done on 1/10/2015 Rough Design started on CAD Determined How it will be actuated (CHAIN) CG Table (Located in Harris Robotics>2015> BUILD SEASON (ROBOT)> Other Design Documents) used to Find optimum mounting position ( As far FOWARD as possible without being past the front wheels) Detailed Work Done on 1/11/2015
