This work breakdown structure demonstrate all the work needed to be done for this project Pathfinder Rover. There are four branches that indicates different job duties and division works assigned to the system and subsystem engineers.

Project Schedule

Top Level Schedule

The charts above shows the preliminary project schedule and tasks that assigned to team members. Each task has a start date and end date indicated the period of the task.

Burn Down and Project Percent Completion

The Burn Down graph shows the overall project progress and remaining time to complete the project.

The Project Overview graph shows the project percent completion directly from calculation.

Mass Report

Our mass is capped to 10 pounds or 4535.92 grams. Looking through the report, we have a contingency of 2519.56 grams. Our total expected mass should be a little over half the mass capacity of the rover. Most of the materials we are using are ABS plastic which is 3D printing. These materials are very light and will help us achieve the goal of staying under 4535.92 grams.

Power Report

The Power budget is how much current our electronics draw. This report is from the specification sheets only. We have not measured the current these electronics draw. Our goal is to use this report to choose a battery that can give us 4 hours of run time. We will have to limit what we put into our design. The motors are the hardware that draws the most current.

Project Cost Estimate

Our budget that we have is 500 dollars. We are reusing some of the parts that were on the previous pathfinder. Most of the parts we are reusing are the electronic parts. We need to figure out how many battery we need to run for 4 hours. We added two batteries onto the cost budget. We have a contingency of $225.12 dollars. With a margin of 82 dollars, we have $143.12 left under the budget.
