Start to Build a Robot On Your Own Q-Scout is a perfect robotics kit for starters who are interested in STEM learning. With all parts ready (65pcs), you can construct a robot in less than an hour. This robot is based on Arduino. It supports programming on mobile and PC with robobloq APP or C language. Schools and workshops can also find Q-Scout suitable for curriculum integration and other educational purposes. Drag-and-Drop Coding In APP center, there is a graphical programming environment based on Scratch 3.0. Not only can you control it in sequence, but also create sophisticated programs with variables and loop commands. Practical Sensors Line Following: Guided by a pair of line tracking sensors, Q-Scout will recognize and follow a black line automatically. Obstacle Avoiding: Thanks to the ultrasonic sensor, it's able to detect and run away from any obstacles. You're not going to hurt Q-Scout, or your furniture. Relax and just play!
