From the project

Telepresence 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.

TelepresenceRobot: common questions

What microcontroller does the TelepresenceRobot use?

The TelepresenceRobot is built around the STM32F102C6, from the STM32 family.

How big is the TelepresenceRobot PCB?

The TelepresenceRobot measures 84.6 × 84.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TelepresenceRobot?

133 components, from 63 distinct parts. The full bill of materials is listed on this page.

Where can I download the TelepresenceRobot design files?

From the joeferner/telepresenceRobot repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TelepresenceRobot design in my own project?

The repository has no license, so all rights stay with joeferner. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TelepresenceRobot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
