Overview
Robot is an open-source printed circuit board by uHappyLogic, from the uHappyLogic/lineFollower repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board with 66 parts on 57 nets, routed with 620 tracks and 16 vias.
It is built around the ATMEGA8A-PU, L293D and CNY70, with the LM339 among its other parts. Its parts include 26 resistors, 17 capacitors, 12 ICs, 5 connectors and 3 diodes. It belongs with the robots and motor control boards and the AVR (ATmega, ATtiny) boards of this library.

Questions
What parts does the Robot use?
66 parts, built around the ATMEGA8A-PU, L293D, CNY70 and LM339. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Robot KiCad files?
From the uHappyLogic/lineFollower repository on GitHub, at the commit this page was made from: the board is KiCad/robot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
