A Johns Hopkins team led by arikslep and faculty member krishnamurthy released OpenTac, a piezoresistive tactile sensor plus ecosystem for automatically designing, customizing, and deploying tactile skins on any robot surface.
Key points:
- Accurately estimates both normal and shear forces.
- Adaptively reads out at kilohertz rates depending on contact sparsity.
- All design files, hardware, software, and firmware are open-sourced under permissive licenses for research and commercial use.
- It's the author's first preprint since starting his faculty position and SciPhy lab at JHU this fall.
