Robots Using ROS: SurfSens: High-Performance Surfboard with Integrated Sensors

Guest post from Urko Esnaola of Tecnalia

Tecnalia and Pukas have cooperated to integrate sensors in a high-performance surfboard to record data of relevant surfing parameters in real operation -- while surfing waves.

The aim of the project is to have information about "what's going on" in a high-performance surfboard while a surfer is riding the board. This will help: (i) surfboard manufacturers: to have valuable information to fabricate optimal performance surfboards; (ii) surfing community: to have very complete information about their surfing technique.

Strain gauges have been included to record the flex and torsion of the surfboard in real operation. One XSens MTi-G integrating gyroscopes, accelerometers, compass and GPS has been incorporated to record data about the surfboard accelerations, speed and movements. Pressure sensors have been installed on the surfboard deck to record data about the surfer's feet position. All the data is recorded in a flash memory stick through an IGEPv2 embedded computer.

After a surf session has been finished, data is transmitted over wifi to a PC. The software system to visualize and process the data has been developed in ROS.

Phase 1 of board construction and electronics performance validation has successfully finished. The exciting Phase 2 has started to do data analysis to find the keys for the mechanical behavior of surfboards and to improve surfer's surfing technique. Professional surfers Aritz Aranburu, Hodei Collazo, Kepa Acero and Mario Azurza have already tested the surfboard. Other professionals like Tiago Pires, Joan Duru, Tim Boal and Eneko Acero are waiting for their chance.
