ROBOTIC ARM DEVICE WITH THREE DIMENTIONAL MOVEMENT

摘要

The embodiments herein provide a robotic arm which is flexible to operate in three dimensional space. The robotic arm is divided into a plurality of arm parts with multiple joints so that the robot arm is moved in three-dimensional space. The length and angle of the different arm parts are adjustable. The functioning of arm parts is controlled by a plurality of motors. The motors are configured to control a change in length and angle of the plurality of arm parts. According to the usage, a motor is used for change the length and a user is enabled to adopt two, four, or six motors or even more motors to change the angle and adjust an access to the target. The user is allowed to assemble the robot by varying the number of attachable arm parts depending on the direction of movement and the degree or direction of rotation.
