Robot arms and grippers do important work every hour of ... They’re typically built out of steel, and powered by brawny hydraulic systems. However, some scientists have gone for a smaller ...

To demonstrate the technique, the researchers created a soft robot "gripper," capable of picking up small objects. The researchers applied hydraulic pressure, causing the gripper to pinch closed ...

Students will learn about different types of soft robots, including pneumatic, hydraulic, and electroactive actuators, and their applications in areas such as bio-inspired robotics, wearable ...
