Open Source Hardware Whisker Sensor

Robot whisker sensors have been researched in many studies but have been difficult or impossible to replicate across labs. An open source hardware robot whisker is presented, including easy-to-follow visual build and test instructions. The design can be used by any researcher as a standard platform, enabling replication and comparison of studies in both open source software and open source hardware. The build instructions have been validated by a complete working rebuild by a researcher independent of the design. Numerical specifications are provided and validated. A rotating multi-whisker module design is also provided, which can be used in robots with rat-like whisker arrays.
