About the Robocat PCB

Robocat is an open source RP2040/RP2350 PCB design by Windfisch, published on GitHub. It is a 2-layer board measuring 90 × 70 mm, with 79 components from 13 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the 4052 and LM324. By type, the board carries 32 resistors, 24 capacitors, 19 connectors and 4 ICs.

It belongs with the robotics & motion designs in this gallery.

From the project

Attempts to build a low-cost (<= 42 Euro) robotic cat, as a smaller variant of boston dynamic's "Spot" robot.

Robocat: common questions

What microcontroller does the Robocat use?

The Robocat is built around the Pico, from the RP2040/RP2350 family.

How big is the Robocat PCB?

The Robocat measures 90 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Robocat?

79 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Robocat design files?

From the Windfisch/robocat repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Robocat design in my own project?

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

Can I test firmware for the Robocat without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
