Robots are cool. Especially those you create on your own. We've recently created this friendly guy to demonstrate how an ESP8266 driven micro-controller like ledunia could control a little robot. So we added 5 servos, four of them allowing our bot to walk and one controls the ultrasonic sensor. Further a mini OLED (I2C) which shows what our bot is going to do next, one ledunia - of course and two 18650 batteries with a step-down-converter. We had to translate some existing Arduino libraries to get control over the servos and learned some new things about I2C... The plastic parts come from our 3D Printer. After some further hours of optimization our little friend did his first successful steps. The ultrasonic sensor is for the object avoidance. Parameters like signal strength, voltage, etc. are monitored by PRTG via HTP Push Sensor. Cayenne or any other cloud solution also works. We will share all software (in this case also the STL files for 3D printing) for this and any other of our projects once we have successfully finished our kickstarter campaign. 

About Ledunia

Ledunia is a powerful WiFi enabled IoT development board with a full TCP/IP stack and microcontroller unit based on the mature of the ESP8266 technology.
