Compete
Now that you have iterated on your arm design and practiced stacking cubes with your robot, you are ready to compete in the Stacked Up Challenge!
The goal of this timed trial challenge is to drive your robot with a Controller to stack cubes on the Field. Your score in the challenge will be determined based on the amount and height of the stacks you have made at the end of the 60 second time period. Watch the animation below to see an example of how your robot could move and stack cubes in this challenge.
In this animation, the Clawbot begins in the center of the lower wall on the Field. There are three blue cubes at the three black line intersections opposite the robot, and two red cubes at the black line intersections on the left and right center of the Field. When the timer starts counting down, the robot first drives and turns to the left to grasp the red cube, then drives to stack it on the blue cube in the left corner. It then reverses and drives to the right side red cube, and attempts to stack it onto the center blue cube. In the final seconds the robot stacks the right corner blue cube onto the center stack.
Follow the steps in this document to complete the Stacked Up Challenge.
Once you have completed the Stacked Up Challenge, check in with your teacher. Ensure you have documented the results of the challenge in your engineering notebook.
Wrap Up Reflection
Now that you have modified your robot design, and competed in the Stacked Up Challenge, it is time to reflect on what you have learned and done in this Lesson. Start a new page in your engineering notebook to begin your reflection.
Rate yourself as a novice, apprentice, or expert on each of the following concepts in your engineering notebook. Provide a brief explanation for why you gave yourself that rating for each concept:
- Designing, building and iterating on your arm design
- Using the arm to stack cubes
- Collaborating with my team members to come up with and test arm designs
Use this table to help you determine which category you fall under.
| Expert | I feel that I fully understood the concept and could teach this to someone else. |
| Apprentice | I feel that I understood the concept enough to compete in the challenge. |
| Novice | I feel that I did not understand the concept and do not know how to complete the challenge. |
