Practice
In the last section, you learned about the elements of a claw and how a claw works. Now, you are going to apply what you have learned to iterate on the build to complete the Improve Your Claw practice activity.
In this activity, your Clawbot will have to drive to an IQ Cube, collect the cube with the claw, and drive it to the opposite side of the Field. You will iterate on the design of the claw to improve your robot's ability to move the cube around the Field. Watch the video below to see how you can apply what you have learned to complete the Improve Your Claw practice activity.
Now it's your turn to complete the Improve Your Claw practice activity!
In this animation, a Controller is used to drive the robot from the center of the bottom of the Field to the cube in the center of the left side wall. Then the robot collects the cube with the claw, and moves the cube to the opposite side of the Field. This animation shows one possible way your robot could move to complete the Improve Your Claw practice activity.
Use this document as a reference to complete the practice activity.
As you complete the Improve Your Claw practice activity, document your designs and testing in your engineering notebook.
- Describe and illustrate your design.
- What is the first thing that you changed on your claw? Why?
- How did it perform in the activity?
- How did you iterate on this design to improve your robot's performance in the practice activity?
See the image on the left for an example of how you can record your design ideas and tests.
Prepare for the Challenge
In Compete (on the next page), you will test your claw designs in the Grab and Go Challenge. Learn how to compete in the challenge, check your understanding, then practice for the challenge.
Watch the animation below to see an example of a Clawbot moving the three cubes from one side of the Field to another. In this animation, the Clawbot begins against the lower wall in the center of the Field. Along the wall to the left of the robot, three cubes are placed, one at each black line. The robot drives forward and turns left to grasp the first cube, then reverses and turns around to place the cube in the area against the right side wall. This process is repeated to move the other two cubes from the left side to the right side of the Field.
Check Your Understanding
Before beginning the challenge, ensure that you understand the rules and setup of the challenge by answering the questions in the document below in your engineering notebook.
