Day 4: Sample Gathering
STEP 1: Return to the “build” instructions and follow the steps to construct a few of the sample boxes shown below. These boxes will serve as important small lunar rock samples for your lunar geology team to analyze and investigate as part of future construction mission planning.
STEP 3: Now it’s time to practice harvesting the samples of lunar material you built above. Go to the same site you used during the rover training session. As before, click “Units” on the left, then select the “Competition Readiness” lesson. This time, focus specifically on Lesson 4 shown below. Before sending your rover out to complete the mission, you must master the process demonstrated in the Lesson 4 video. Practice, practice, practice—you’ve got this!
STEP 4: Now your goal is to combine everything you’ve learned over the past few days of coding and driving your rover to accomplish a major mission. Place one of the lunar samples you plan to collect in a region you previously surveyed, then place a lunar rock hazard directly between the starting point and the sample.
Starting from the beginning, with your rover facing the lunar rock head-on, program it to successfully navigate around the hazard, collect the lunar sample, and return it to your geology team for analysis. This challenge will require you to apply all the skills you’ve developed—it’s tough, but you’ve got this!
Once you have successfully accomplished gathered your sample , record a video of your rover in action and upload using the QR code below. In the “Subject” area, include your first name and/or your team members’ names. Click here to see all uploaded videos.
BONUS CHALLENGE: If you have extra time, try the bonus challenge in Training 3: Reacting to Lines. Learn how to use the color sensor to follow a line that leads to the sample—instead of avoiding the obstacle with the distance sensor!
