AI Technical Summary
When clamping materials, the clamping force of existing robotic clamping structures is too small or too large, resulting in unstable clamping or damaged materials, making it inconvenient for transportation.
A robot clamping structure including a substrate, a servo motor, a screw, a clamp and a pressure sensor is designed. The clamping plate is clamped by the servo motor driving screw, and the pressure sensor monitors the pressure applied to the material in real time. When a certain value is reached, the servo motor stops running to avoid the clamping force being too large or too small.
It effectively prevents material damage caused by excessive clamping force, and at the same time avoids unstable clamping caused by excessive clamping force, ensuring stable clamping and safe transportation of materials.
