## What is CB1 Blockly?

CB1 Blockly Programming App for Robotics Workshop

For use with the engineering kit “Robotics Workshop” by Thames & Kosmos
 
CB1 Blockly is a visual programming app based on Blockly. It allows you to write programs to control the robots you build with the Robotics Workshop kit. You can write visual programs with drag-and-drop code blocks in the app and then send the programs to the CB1 core controller on your robot models to make the motors turn, the buzzer sound, and the LEDs flash. You can write programs that use sensor input from the light sensor, sound sensor, distance (ultrasonic) sensor, and touch sensors to command your robots to interact with their environments.
 
App Features
• Connect to your models via Bluetooth connection.
• Programming mode lets you script and save up to 20 programs.
• Ten demo programs are preloaded to work specifically with the ten robot models in the kit.
• A simple, visual programming language lets you use input data from two touch sensors, distance (ultrasonic) sensor, light sensor, sound sensor, and variable resistor knob to control four motors, 2 LEDs, and speaker.
• Use the 64-page, step-by-step illustrated manual included in the kit to learn how to build the models and write the programs.

## Key features

- Visual programming with drag-and-drop blocks
- Control motors, LEDs, and buzzer
- Utilize various sensor inputs
- Bluetooth connectivity to robots
- Save up to 20 custom programs
- Includes 10 preloaded demo programs

### 4/5 — Can’t connect Bluetooth

*2023-12-21*

Me and my grandmother bought this as a stem experiment and wanted to be able to code it but can’t connect Bluetooth so we can’t play the robot. Please fix this

### 2/5 — HELP!!!

*2023-05-12*

HELP!  My long lost mother got this for me on my 1st birthday!
Idk how to use it cause my long lost mom who came back after 20 years after searching for milk gave me this when I was 1 year 3 month 4 weeks 3 days 29 minutes and 37 sec old, she thought I was intelligent instead of retarded, but I have to say I’m REALLY retarded, my little fingers can’t even work well cause I have cancer stage 3000000 and the black plague, I’m almost 2.o92849740734 years old and I still in high school, my teacher gonna kill me cause I got a A+ in every subject when I’m literally 2.092849740734 years old, SOMEONE HELP!!!

### 1/5 — Creating a variable freezes my app

*2020-09-09*

I was trying to create my own program but found it wouldn’t let me parse or run it. I tried a few things and found that creating a variable caused any other button than code blocks to be unresponsive. I can still place the code blocks but nothing else works.

### 2/5 — Help me!

*2020-01-26*

I need real help! My dad is about to be real mad in 10 minutes approximately! My dad spent 200$ on it and I do not know how to program it! I got it for Christmas and I’m so dead because my dad is going to think I’m a spoiled 10 and a half year old boy but actually doesn’t know how to program it! What is a lux and a knob? Tell me! Please! How do I even program it? I lost the Manuel, I think! HELP! PLEASE!

### 1/5 — Buyer beware

*2017-12-31*

Bought this thing and the build was fun but as far as the software to run the toy - it doesn't work with any functions.   Bluetooth will connect on occasion and the motors will load up but not run.       Alot of money for a toy hard to get to run.     Shero is a much better option to learn coding

### 1/5 — Not working

*2017-03-21*

The app isn't working.  Had written a program for my daughters science fair which is tomorrow night and went to use the app and the repeat function for time is way out of wack.  Anything less than a value of 20 and it goes for about a second during that command.  Anything 20 and above and it goes indefinitely.   HELP!!! PLEASE!!! Im about to have a very frustrated 7 year old in less than 18 hours.
