The Atlas robot that is used for the robotic class in Central Washington University does not process any sensor that will provide safety for the users or itself. The robot was made by a student and is capable of functioning like any other articulated robot that is used in the industry, but it is lacking any self-awareness for safety. This project aims to improve the robot’s safety with the use of a sensor by attaching it to the claw of the robot. What this will accomplish is reducing the chances of the robot breaking any object that it is grabbing onto or hurting either the user or itself in the process.
To make sure that the robot can grab an object without damaging anything, a pressure sensor is used to measure the robot’s grip force. By attaching the sensor to the robot’s claw, it will read any force that is applied to the claw’s grabbing point and make sure that it is not using too much force on the object. The result showed that with the use of the sensor, the robot can reduce any damage that it might cause by stopping its movement before damage is done to itself or the object.
The result shows that sensors do have an impact on the robot’s self-awareness. On this basis, it is recommended that a pressure sensor is used as a key part in designing an articulated robot that is capable to control its grip force for safety purposes.
