| Description | small bot with 4 legs and ESp8266 WiFi Chip (based on miniKame) |
| Author(s) | Peter, Severin, Jörg, Heiko, Jorgen, ThomasE |
We want to build some small miniKame based bots and extend them as MuMaLab bot collective mesh network and many more..
3D printed parts
original files: http://www.thingiverse.com/thing:1265766/#files These parts only fit for the expensive Servos, the cheap ones use other screws (only 2 instead of 4)

We decided to use a 16 channel I2C PWM controller to drive all servos smooth. The reason is, that ESP8266 has no full realtime OS support! (because of doing the WiFi stuff builtin with interrupts)
We use this 16 channel I2C PWM controller
The software is also changed to use I2C instead of making PWM by ESP8266
