Presentation Outline Review of Objectives Completed Tasks Preliminary Results Unanticipated Challenges Progress vs. Schedule Future Plans
Review of Objectives Balance 3D Arm Driven Inverted Pendulum Identify System Parameters Design Physical System Fabricate System Design / Optimize Controller
Completed Tasks SolidWorks model Equations of motion Inertia calculations Control analysis batch files Universal joint manufacturing Basic friction identification
Preliminary Results Batch Modeling Torque Saturation Approach Example Configurations Unstable System Configurations Uncontrollable System Configurations Torque Saturation
Batch Modeling Approach Vary three model parameters Mass of end weight Length of upper arm Length of lower arm
Batch Results Test Cases (1) Mass of End Weight Varied
Batch Results Test Cases (2) Length of Upper Arm Varied
Batch Results Test Cases (3) Length of Lower Arm Varied
Unsuccessful Configurations Unstable System Configurations Torque Saturation Uncontrollable System Configurations Error in Inertia Calculations
Torque Saturation Low motor torque Solutions Higher gear ratio Larger motors
Unanticipated Challenges Low motor torque Counterweights Restricted range of motion Spacers
Progress vs. Schedule System modeling Linearization Control design Parameter identification System sizing Manufacturing Performance analysis On Target On Target On Target Not Finalized Not Finalized In Progress On Target
Future Plans System specific friction identification Equation linearization Controller optimization System manufacturing
