Abstract
The present invention relates to a robotic arm, including: an upper arm and a front arm; a first joint structure, by which the upper arm and the front arm are articulated together; a second joint structure, arranged at an end of the upper arm and/or an end of the front arm; a first driving mechanism, arranged in the upper arm; and a second driving mechanism, arranged in the front arm, where the first joint structure includes a first force amplification apparatus and a first locking element, the second joint structure includes a second force amplification apparatus and a second locking element, and the first driving mechanism and the second driving mechanism apply an acting force to the first locking element and/or the second locking element by the first force amplification apparatus and/or the second force amplification apparatus. According to the robotic arm in the present invention, the force amplification apparatuses are arranged in the joint structures, which amplifies a locking force and enables the robotic arm to meet the requirements for large load applications under a miniature condition.
