Use a project management tool to generate a Gantt chart for building the robot. If you wish to work with two or three people that is OK.
You can turn this project in on the Homework 4 moodle page. If you are working with someone, turn in one copy; but clearly indicate who is working with you.
I would prefer that you use either Planner or Microsoft Project for this assignment. Whatever you use, turn in a PDF file or your Gannt chart in addition to the data file for your project management tool.
