There is a close relationship between robot arm deployment and operating space. Robot arm extension refers to the maximum length of a robot arm when fully extended, while operating space refers to the spatial range that the robot can reach within its maximum arm extension range. Below is a detailed introduction to the relationship between the two:
Robot arm exhibition
Definition: Robot arm extension refers to the maximum length of a robot arm when fully extended, usually the distance from the last joint of the robot to the base.
• Influencing factors: The design of the robot, the number and length of joints can all affect the size of the arm extension.
Operating space
Definition: Operating space refers to the spatial range that a robot can reach within its maximum arm span, including all possible pose combinations.
• Influencing factors: The arm span, joint range of motion, and degrees of freedom of the robot can all affect the size and shape of the operating space.
relationship
1. Range of arm extension and operating space:
The increase in robot arm extension usually leads to an expansion of the operating space range.
However, the operating space is not only determined by arm span, but also influenced by joint range of motion and degrees of freedom.
2. Arm span and shape of operating space:
Different arm extensions and joint configurations can result in different shapes of operating space.
For example, robots with longer arms and smaller joint range of motion may have a larger but shape limited operating space.
On the contrary, robots with shorter arm span but larger joint range of motion may have a smaller but more complex operating space.
3. Arm span and accessibility:
A larger arm span usually means that robots can reach farther distances, increasing the range of operating space.
However, if the range of joint movement is limited, even with a large arm span, it may not be possible to reach certain specific positions.
4. Arm span and flexibility:
A shorter arm span can sometimes provide better flexibility because there is less interference between joints.
A longer arm span may cause mutual interference between joints, limiting flexibility within the operating space.
Example
Robots with smaller arm span: If designed properly, they can achieve higher flexibility and precision in a smaller operating space.
Robots with larger arm span: can work in a larger operating space, but may require more complex joint configurations to avoid interference.
conclusion
The arm span of a robot is an important factor in determining the operating space range, but the specific shape and size of the operating space are also influenced by other factors such as joint range of motion, degrees of freedom, etc. When designing and selecting robots, it is necessary to comprehensively consider the relationship between arm span and operating space to meet the specific application requirements.
