Libraries
This repository have all the main Otto DIY robot libraries for Arduino compatible boards
Installation:
- Download the .zip Otto libraries here
- Open Arduino IDE and navigate to Sketch > Include Library > Add .ZIP Library. At the top of the drop down list, select the option to ¨Add .ZIP Library¨.
- You will be prompted to select the library. Navigate to the .zip file's location, that you just downloaded and open it.
- In the main window you will see in the bottom back area a message that it has been installed.
- To verify they are properly installed, go to Sketch > Include Library menu. You should now see the library at the bottom of the drop-down menu. That means is ready to use Otto example codes! you can find them in File > Examples > OttoDIYLib for more details or other way to install libraries visit this link
Compatibility:
We are making the libraries more modular and simple than ever, so that you can expand your robot functionallities as you go or you can change components based on your needs or the type of robot you want to make. You can use both AVR boards like Arduino Nano or Arduino UNO and also ESP8266 or ESP32 boards by changing the definition of the pins.
All our bipedal robots are compatible with this libraries.
- Otto.h and Otto.cpp contains all the main functions
- Otto_gestures contains all the gestures functions
- Otto_mouths contains all the mouth functions
- Otto_sounds contains all the sound functions
- Otto_matrix contains all the matrix functions
- US contains the functions of the ultrasonic sesnor
- SerialCommand is for Bluetooth communication vis Software serial
- Oscillator is the main algorithm for the servos ¨smooth¨ movement
Wiring:
These are the default connections fir AVR Arduino boards, but some Otto remixes do not use all pins or interchange them according to their needs, you can do that too, play with the pins and add new sensors, more motors, displays, LEDs and so on.
