Getting the Students Ready to Build
How can motors make the Robot Arm more useful? Let’s add motors and switches and find out!
Facilitate the Build
- InstructInstruct students that they are going to combine groups to motorize the Robot Arm. As they complete the Robot Roles & Routines sheet, explain that there will be more than one Builder and Journalist for this Lab. Use the Suggested Role Responsibilities slide in the Lab Image Slideshow as a guide for students to complete this sheet.
Motorized Robot Arm build instructions to each group.
Journalists should gather the materials on the checklist together.
the building process.
- Builders can begin building.
- Journalists should assist with build instructions as needed.
- Ask questions to prompt students’ thinking about mechanization such as,
- Where does the motor get its power from?
- How do you think the motor will change the arm’s movement? Will it be faster or slower?
- Do you think the motor will make the arm easier or more difficult to control? Why?
- OfferOffer positive reinforcement to groups that share responsibilities well, and offer support to help those who need to better define their roles within the group.
- Deconstruct Carefully - If students are adapting their previous build, remind them to be careful in their deconstruction, as they will be reusing parts of the build again. Use the Pin Tool to help remove pins, or push shafts through the holes. Remind students that if something comes apart accidentally, it can be fixed. (Refer to the individual Motorized Robot Arm Build Instructions for additional support in this case.)
- Check Your Batteries - Use the VEX Classroom App to check the status of the GO Batteries, and charge if necessary before the Lab. For more information about the VEX Classroom App, please read the Using the VEX Classroom App VEX Library article.
- Specify Roles within Builder and Journalist - Since there will be multiple students in each role because of the need for two VEX GO Kits per build, help students share the responsibilities in a tangible way. Use the Suggested Role Responsibilities slide in the Lab 2 Image Slideshow as a guide, have students take turns within each role.
- Have a Plan for Combining Groups - In some cases, it can be helpful to think ahead and have a plan for which groups will work together before the Lab begins. Then, when instructing students to combine groups, the teacher can assign groups to be partners quickly, to minimize student debate or distraction.
