Using an End Effector

Teacher Portal
• Time: 1 week

### Description

In Lab 6, students will investigate how adding to the z-value of a coordinate lifts the marker off of the whiteboard on the Workcell. Then, they will explore how to store (x, y, z) coordinates in a 2D list in order to draw two triangles using a dry-erase marker. Students will also be reading about the relationship and value of accuracy and repeatability with industrial robots. Finally, students will be challenged to create a VEXcode V5 project where the arm draws ‘VEX’ on the whiteboard.

### Essential Question(s)

• What are 2D lists and how are they used in programming a robot?

### Understanding(s)

Students will understand:

• How to use 2D lists to store values in a VEXcode V5 project.

### Objective(s)

• Identify that a 2D list is made up of rows and columns.
• Identify that a 2D list stores multiple sets of numeric values that are related.
• Identify how to create a 2D list in VEXcode V5.
• Identify how to use variables in a VEXcode V5 project.
• Identify how to use a repeat loop in a VEXcode V5 project.
• Identify that an index is used to represent the position in a 2D list in their VEXcode V5 project.
• Identify how to launch VEXcode V5.
• Identify how to open an example project.
• Identify how to name and save a VEXcode V5 project.
• Identify how to add blocks to a VEXcode V5 project.
• Identify that the third number of a coordinate indicates how far the arm will travel from the origin in the z-axis.

### Vocabulary

2D List
A block in VEXcode V5 which allows the storage of multiple values in rows and columns. Also known as a 2D array.
Index
A numeric representation of an item's position in a list or other sequence.
End of Arm Tooling (EOAT) / End-Effector
End-Of-Arm-Tooling or an end-effector is the term used for robotic tooling for manipulating parts mounted on the end of the robot arm. Examples are grippers, magnets, welders, paint guns, etc.

### Educational Standard(s)

• Next Generation Science Standards (NGSS) HS-ETS1-2: Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
• International Society for Technology in Education (ISTE) 6b: Students create original works or responsibly repurpose or remix digital resources into new creations.
• Computer Science Teaching Association (CSTA) 3A-AP-14: Use lists to simplify solutions, generalizing computational problems instead of repeatedly using simple variables.
