The article discusses the design and performance of PAUL, a pneumatic actuated robot developed at the Centro de Automatica y Robotica in Madrid. Researchers analyzed its bending capabilities through controlled experiments, determining that PAUL achieves a maximum bend of 40° to its vertical axis. This performance holds steady even when additional segments are added, though it remains below levels achieved by some competing technologies. The study emphasizes the innovative material selection and manufacturing process that contribute to the functionality of soft robots like PAUL.
The results show that PAUL can bend up to 40° without a significant decrease in bending capacity when additional segments are added, highlighting its robustness.
In the bending experiments, it was observed that PAUL's performance, while below some standards, is enhanced by the flexible design and pneumatic actuation technology.
