Grabber Preview
- 8 - 15 years old
- 30 minutes - 1 hours, 40 minutes
- Beginner
Description
-
Students will build a device that uses scissor linkages to convert the direction of motion and explore the mechanics of a scissor linkage.
Key Concepts
-
Linkage
-
Force
-
Motion
-
Scissor Lift
Objectives
-
Create a build that can alter its size by using scissor linkages.
-
Identify the movement of objects using this build.
-
Identify scissor linkages within professional applications like lifts and explain their ability to convert motion.
-
Apply techniques for strengthening the Grabber's scissor linkages (doubling, cross-linkages, and relocating pivot points).
Materials needed
-
VEX IQ Super Kit
-
Engineering notebook
Facilitation Notes
-
Ensure all required parts for the build are available prior to starting this STEM Lab.
-
Building with some of this build's parts can be challenging. See the Appendix for tips as needed.
-
There is a risk of users being pinched as the Grabber extends and retracts. Anyone handling the Grabber should be careful of its pinch points.
-
An engineering notebook can be as simple as lined paper within a folder or binder. The notebook shown is a more sophisticated example that is available through VEX Robotics.
-
The approximate pacing of each section of the STEM Lab is as follows: Seek - 25 minutes, Play - 30 minutes, Apply - 10 minutes, Rethink - 30 minutes, and Know - 5 minutes.
