Robotics may have evolved and redefined majority of the industrial sectors but there still exists a huge bridge between humans and machines in the geriatric care and health. The current focus is to help robots to safely and carefully interact or manipulate with delicate objects, organisms and also to use new tactics to enhance their objective while making them softer and flexible. In robotics, the researchers are trying to make a safe and handy robotic gripper with human-like competencies. However, the major challenge in soft robotic grippers is adding conventional sensors to the robotic fingers. They plan to integrate proprioception, which is soft gripper in order to add a sense of its own position and movements for a better execution of task. But, the rigidity and mechanical properties of soft parts makes the use of traditional sensors difficult. Additionally, the use of a same type of proprioceptive sensation to design the soft grippers is also a drawback.
This is why the researchers from Ritsumeikan University have been trying to develop new soft robotic fingers using multimaterial 3D printing technology that uses a built-in proprioception sensor. The use of new design strategies provides advantageous and safer soft robots. Furthermore, the inflation chamber present in the soft finger makes it easily controllable and bendable depending on the input air pressure. The stiffing is also possible by creating vacuum in different chambers with the help vacuum jamming. These functions together form a three-finger robotic gripper that will properly hold or grasp an object by maintaining the necessary force.
The researchers added a single piezoelectric layer in the vacuum jamming layers as a sensor in order to produce a voltage difference when the material is under pressure. The researchers used this step as a sensing mechanism in the robotic finger. By adding a microstructured layer in between the jamming, the pressure distribution on the piezoelectric material is enhanced which in turn increased the finger's sensitivity. Moreover, the use of 3D printing helped integrating sensing and stiffness mechanism in the designs of the robotic finger. The basic goal is to provide better control and sensing elements without hampering its dynamic behavior. For low-power applications, this self-powered invention is a remarkable feature.
