Fall 2016 Solar Panels: Project Summary

By Inna Echual (Project Manager) Project Overview Executive Summary Project Objective The design of the Fall 2016 Pathfinder project was taken directly from NASA’s Mars Exploration Rovers, Opportunity and Spirit. The Pathfinder will be designed to be self-sufficient using solar panels, as well as implement the solar deployment mechanism employed by the two aforementioned rovers. […]

Fall 2016 Solar Panels: Mechanical Design *

By Ridwan Maassarani (Design and Manufacturing) Approved by Inna Echual (Project Manager) As a requirement, solar panels had to be manufactured that is of the same form factor as the spirit and opportunity mars rovers that were designed by NASA. To accomplish this, my team and I visited JPL and was able to find model […]

Fall 2016 Solar Panels: PCB Layout *

By Ridwan Maassarani (Design and Manufacturing) Approved by Inna Echual (Project Manager) A custom PCB that can drive five stepper motors was needed to reduce the footprint on the rover. The custom PCB would also cut down on cost since stepper motor drivers that can run 3 or more motors can gen expensive. It was […]

Fall 2016 Solar Panels: The Solar Panel Sandwich (the “Encapsulation”)

By Ridwan Maassarani (Design and Manufacturing) Approved by Inna Echual (Project Manager) Introduction In order to secure the cells onto the panel, one must consider the way of “sandwiching” the cells onto place. A rubber substrate was used for insulating the solar cells from the aluminum sheet. Here, I will review the “sandwich” method of encapsulation. […]

Fall 2016 Solar Panels: Requirements Update

By Stephan Khamis (Missions, Systems, and Test) Approved by Inna Echual (Project Manager) Introduction This blog post contains our most up-to-date requirements for the Solar Panel system of the Pathfinder project. Within this blog post you will learn about the changes we have made since the CDR to update this document. Updated Requirements Solar Panel […]

Fall 2016 Solar Panels: System Block Diagram Update

By Stephan Khamis (Mission, Systems, and Test) Approved By Inna Echual (Project Manager) Introduction As a result the feedback we received during the critical design review (CDR), we decided the system block diagram for our system. This blog post contains our most up-to-date system block diagram for the Solar Panel system of the Pathfinder project. […]

Fall 2016 Solar Panels: Choosing Panel Thickness (Stress Tests)

By Ridwan Maassarani (Design & Manufacturing) Edited and Approved By Inna Echual (Project Manager) Objective: The thickness of our panels must be carefully chosen as “too large” of a thickness could result in additional weight, possibly causing unnecessary strain and bending. Though the chassis could withstand our panels weight a maximum 50 lbs (as stated by the chassis […]
