GenTact Toolbox

A Procedural Whole-Body Sensor Design Pipeline

A computational pipeline for generating custom, context-driven whole-body tactile skins that conform to any robot geometry.

Abstract

Developing whole-body tactile skins for robots remains challenging due to one-size-fits-all approaches. GenTact introduces a computational pipeline for creating custom, context-driven tactile skins tailored to both robot geometry and task requirements.

The Pipeline

  1. Procedural Mesh Generation — Automatically generates sensor layouts using Blender’s Geometry Nodes.
  2. Simulation & Task-Driven Optimization — 1:1 import into Isaac Sim for contact simulation and sensor placement refinement.
  3. Multi-Material Fabrication — Fully 3D-printable skins and molds with multi-filament support.

How It Works

GenTact consists of a Blender addon for procedural design and an Isaac Sim extension for simulation. The final output is a multi-layered mesh containing both the skin mold and embedded sensors — ready for multi-material 3D printing.
