Activity (Hands-On)Grades 6 - 8
Biomimicry: Echolocation in Robotics
Materials List
Each group needs:
- LEGO MINDSTORMS EV3 robot, such as EV3 Core Set (5003400) at https://education.lego.com/en-us/products/lego-mindstorms-education-ev3-core-set/5003400#lego-mindstorms-education-ev3 (Note: If not enough robots are available for one per group, share the robots you have among several groups, or use one robot for the class, sharing data with everyone.)
- 2 "objects" found in the classroom, for the robot to sense at the 100 and 200 cm locations (perhaps bottles or boxes)
- stopwatch
- Pre-Activity Echolocation Worksheet (PDF), one per student
- Echolocation Activity Datasheet (PDF), one per student
- Post-Activity Echolocation Worksheet (PDF), one per student
- echolocation_program_10.ev3 (EV3)
- echolocation_program_25.ev3 (EV3)
- echolocation_program_50.ev3 (EV3)
- echolocation_program_75.ev3 (EV3)
- echolocation_program_90.ev3 (EV3)
Note: This activity can also be conducted with the older (and no longer sold) LEGO MINDSTORMS NXT set instead of EV3; see below for those supplies:
- LEGO MINDSTORMS NXT robot, such as NXT Base Set
- echolocation_program_10.rbt (RBT)
- echolocation_program_25.rbt (RBT)
- echolocation_program_50.rbt (RBT)
- echolocation_program_75.rbt (RBT)
- echolocation_program_90.rbt (RBT)
To share with the entire class:
- ruler, marked in cm and inches
- masking tape, to mark off the robot course
