What type of foam tiles are used for the field floor?

The field floor in FTC competitions is specifically designed to provide a safe and effective environment for the robots to operate. Interlocking soft foam tiles are used because they offer a combination of shock absorption and traction, which is essential for the moving parts of the robots during matches. This type of flooring helps reduce the impact on robots and any potential damage from falls or collisions, while also ensuring that robots can maneuver effectively without slipping.

The other materials, such as hard plastic tiles, rubber tiles, and vinyl tiles, may not provide the same level of cushioning or grip necessary for competitive robotics. Hard plastic surfaces can lead to increased wear and tear on robot components, while rubber and vinyl options might not provide the necessary level of foam cushioning that aids in safety and performance during the games. Therefore, interlocking soft foam tiles are the optimal choice for the competition field floor.
