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: Creating a Port Expander Using IC MCP23017

By Jose Rodriguez (Electronics & Control) Approved By Inna Echual (Project Manager) Objective: Because of our current design, a port expander is needed because there are no more available pins on our Arduino to read data from the reed switches. The reed switches will be used to halt the panels from cocooning more than it needs […]

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 […]

Fall 2016 Solar Panels: I2C Communication Experiment

By Jose Rodriguez (Electronics & Control) Approved By Inna Echual (Project Manager) Objective: Currently, we will be using our own Arduino Leonardo while the Thursday Pathfinder group (referred to as the chassis group) will also have their own Arduino Leonardo. The solar panels Arduino and chassis Arduino will communicate using I2C interface on Arduino. In order […]
