When dancing with a partner, forces and torques from each person influence the motion of the other. Each person’s motion is therefore partially controlled by themselves and partially controlled by their partner.

HapticCopiloting: common questions

What microcontroller does the HapticCopiloting use?

The HapticCopiloting is built around the ESP32-DEVKITC-32UE, from the ESP32 family.

How big is the HapticCopiloting PCB?

The HapticCopiloting measures 119.4 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HapticCopiloting?

84 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the HapticCopiloting design files?

From the bri-yan/HapticCopiloting repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the HapticCopiloting design in my own project?

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

Can I test firmware for the HapticCopiloting without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
