This robot used ESP8266 as microcontroller. This robot has 6 legs with 2 servos in each leg, so the total servos that used is 12 servos. So, the robot used PCA9685 PWM I2C module to handle the servos. Then, the robot has difficulty walking straight, so it was used Magnetometer HMC5883L to control the direction when it starts to walk not straight. To operate this robot, we can use Blynk app that connected with ESP8266 by same WiFi.
