- 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

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.

From elementary school through college, VEXcode is a coding environment that meets students at their level. The intuitive layout of VEXcode allows students to get started quickly and easily. VEXcode is consistent across Blocks and Text, across VEX IQ and VEX V5. As students progress from elementary, middle, and high school, they never have to learn a different blocks, code, or toolbar interface. As a result, students can focus on creating with technology, not trying to navigate a new layout. Drive Forward is the new Hello World We all know that robots attract kids to learn. VEX Robotics and VEXcode are providing opportunities for students of all ages to participate in learning the code that makes these robots work. VEX makes computer science come to life through collaborations, hands-on projects, and engaging experiences. From classrooms to competitions, VEXcode helps to create the next generation of innovators. Drag. Drop. Drive. VEXcode Blocks is the perfect platform for those new to coding. Students use the simple drag and drop interface to create functioning programs. Each block's purpose can easily be identified using the visual cues like its shape, color, and label. We've designed VEXcode Blocks to allow those who are new to robotics to get their robot up and running faster. Now, students can focus on being creative and learning computer science concepts, not stuck trying to figure out the interface. More accessible than ever VEXcode even helps across language barriers, allowing student to read blocks and comment programs in their native language. Drag & Drop. Powered by Scratch Blocks. Students and Teachers will feel instantly at home with this familiar environment. Video Tutorials. Grasp concepts faster. Built-in tutorials cover every aspect needed to get up to speed fast. And more tutorials are coming. Help is always there. Getting information on blocks is fast and easy. These resources were written by educators, in a form both teachers and students will grasp quickly. Drivetrain Blocks. A breakthrough in simplicity. From driving forward, making precise turns, setting speed, and stopping precisely, VEXcode makes it easier than ever to control a robot. Setup your VEX robot. Fast. VEXcode's device manager is simple, flexible, and powerful. In no time at all you can setup your robot's drivetrain, controller features, motors, and sensors. 40+ Example projects to choose from. Jumpstart your learning by starting with an existing project, covering every aspect of coding, controlling robots, and learning to use sensors.
