2. Description
With bass wood as its structural material, we specially design a greeting robot learning kit.
This kit integrates two servos and an ultrasonic sensor, which are compatible with micro:bit boards and ESP32 Easy Coding Boards. It can detect the distance of objects and wave arms. We write codes via Makecode and KidsBlock to achieve multiple creative and interesting functions.
With this kit, you can master basic sensor knowledge and have an excellent opportunity to learn programming. It is also a perfect combination of learning and entertainment which stimulates your creativity and talent.
3. Features
Simple assembly: For convenience, the assembly is easy and simple so that you may complete installations quickly.
Distance detection: The ultrasonic sensor detects the distance of surrounding obstacles in real time.
Greeting robot: Two servos control the arms of the robot to perform motions like greeting. Servo angle range is 0~90°.
Modular design: The robot adopts a modular design, so you can freely combine and replace different modules according to needs for personalized customization.
Multiple programming: Makecode and KidsBlock programming are available, which meet the diversified programming needs and expand the range of learning.
4. Assembly
ATTENTION: If you are a beginner, please learn the Micro bit Basic Projects first. The angle of the servo need to be set before assembling. You may not know how to do it without the basic projects.
Click to learn Basic Projects.
Step 1 Calibrate servo angle
Wiring:
For MicrobitV2/ESP32 development board, set servo A and B angle to 0°.
Click to download the servo codes.
After uploading code, the servos rotate to 0°. Disconnect the servos and put them aside, preparing for later installation.
Step2
Step3
Wire up the battery holder. Although it is anti-reverse ports, please correspond to positive and negative poles.
