The μBot is an educational floor robot based on ESP8266. It's still a prototype (v2.0).

This repository summarize the whole project:

• Repositories related to the floor robot:
  • The PCB files: hu-zza/uBot_PCB
  • The 3D files: hu-zza/uBot_frame
  • The firmware: hu-zza/uBot_firmware
  • And its API documentation: hu-zza/uBot_API
• The link between the robots and the server: hu-zza/uBot_Hub (soon)
• The webpage ... soon or later, until that: https://ubot.hu

The design allows great flexibility in assembling. You can use SMT (surface-mount technology), THT (through-hole technology), or the mix of these. The "easy solderability" is my primary aim, so the solder pads are oversized too and the surface is not so dense.
