README
README.mdTelepresence Robot
After seeing a commercial for a Telepresence robot on TV, I knew I wanted to play with one, but after looking at prices I didn't want to pay for one.
I used an Android Nexus 7 tablet for the video conferencing. A custom PCB with an STM32 ARM processor and an FTDI USB chip to connect the Android tablet with the motors.

Questions
How big is the TelepresenceRobot PCB?
It measures 84.6 × 84.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TelepresenceRobot use?
133 parts, built around the STM32F102C6T6A, MC33926PNB, AP6502SP and BQ24450DW. 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 TelepresenceRobot KiCad files?
From the joeferner/telepresenceRobot repository on GitHub, at the commit this page was made from: the board is hardware/main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TelepresenceRobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask joeferner before reusing the design.
