What’s a Control Room?
A Control Room (CR) is basically a room in the cloud that lets teachers and students devices, and specifically the Meeper App on their devices to communicate with each other to control and code BOTS and Circuits that a teacher has in their location.
A student device and Meeper App will send commands and code to a Teacher device and Meeper App. The Teacher Meeper App then communicates with the teacher’s BOTS and MCC’s to execute the controls and code that the student is sending.
Once you have set up your Control Room (CR). Your students may join your Control Room by entering the CR Code that you provide for them.
Student Control of Teacher BOTS & Circuits
Once a student has been given Control, they can go to the BOT Control or Circuit Control screens and control the Teacher connected BOTS and Circuits in real-time.
Sending Code to Teacher
Once you have given a student control, they can send the Teacher BOTCode or Blockly code. The student sends the teacher code when they push the Run code button on the BOTCode or Blockly code screen.
Note: Ensure all students/teachers have the latest Meeper App update to ensure best interoperability and the latest features in the Control Room.
Coding Tips n Tricks
KLIKS are basically a proxy for a unit of time that are used for BOTCode and Blockly commands. We use KLIKS as devices and communications can vary and we want students to focus on the concepts and not the precision of a time measurement. In general, 10 KLIKS is one second. If you run a program command for 10 KLIKs, the BOT will run that command for roughly one second.
Note, the BOTS have 3 speeds. You can set the speed when you set the KLIKS. Click on the command to change both KLIKS and Speeds on each command. Note that the speed and KLIK combination will vary to create the path you require.
BOT Spins & Turns
BOTS have two types of turning commands.
- Turns are executed by the BOT turning one rear wheel in the direction of the turn. The other wheel does not move. This makes for a wider turn.
- Spins are executed by the BOT spinning one rear wheel in the direction of the turn forward and the other rear wheel in reverse to create a tighter spin with more speed/energy. On a slippery surface spins will usually execute a bit better than turns.
Access Calibration from MyBOTS and then the wrench next to the name of your BOT to calibrate your BOT turns and spins. Your calibration for a BOT/device combination is stored on your device so you don’t have to recalibrate the next time you use that same BOT/device combination.
Physical BOT Setup & Surfaces
As mentioned, slick surfaces can cause the BOT to spin out or continue to coast at high speeds. It’s a good learning experience to discuss the factors that can impact the performance of your BOTS. Discuss with students different options for adjusting to different conditions. Incorporate this in to your project and solutions as needed.
