| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
The educational goal in this robotic class is for students to control the robot to move. The topic in COSMOS make this really fun activity for students to use wireless communication device (walkie-talkie) to locate the robot. While they are playing this hide and search game. The COSMOS concept I want them to understand is that when the walkie-talkie is too close to the mobile node (signal transmitter) since they are on the same frequency. I will create a signal interference and this is why they hear the noise.
|
| Short Description and Walk-through of the experiment |
- In the first session, students will learn about how walkie-talkies work (Check presentations for details). The teacher will show them what happens when the walkie-talkie come close to the mobile node. (It creates a noise). Students will use this idea to locate the robot. Students should also decide their group and their plan for the next day in this first session.
- In the second session, students will be separated into 5 different groups. One group will control the robot to hide. The other 4 groups will use the walkie talkie try to locate the robot based on the “noise”.

| Testbed mapping of the experiment |
Testbed nodes-sensors can provide real-time data on temperature, humidity, and CO2 and help manage certain fragile or threatened ecosystems.
