Vertical Articulated Robot Base with Extended Columnar Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In workspaces where humans and robots collaborate, floor-installed robots occupy valuable space, limiting the available human workspace, and existing ceiling-suspended robots are not practical for all environments.
Innovation Solution
A 6-axis vertical articulated robot design featuring a base with a flat installation surface and a columnar member extending upward, allowing the first arm to pivot below a horizontal axis, with the columnar member being longer and having the same sectional area as the arm, enabling a lightweight, slim design that ensures a large human workspace without occupying excessive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot is installed on the floor surface, then the robot can be easily installed and maintained, but the workspace is occupied by the robot, limiting the human workspace
Solution Approach 1:
The patent transitions the robot from traditional floor installation to ceiling suspension, changing the installation dimension from horizontal (floor) to vertical (ceiling). This dimensional change allows the robot to operate in the vertical space above the human workspace, eliminating the conflict between robot installation area and human workspace while maintaining ease of installation through the base structure with flat installation surface member.
2Stability of the object's composition
If the columnar member is made longer to extend beyond the first arm, then the center of gravity stabilizes and prevents falling during relocation, but the device complexity increases
Solution Approach 1:
The columnar member extends beyond the first arm to act as a counterweight that stabilizes the robot's center of gravity. This extended columnar structure prevents the robot from falling during relocation by positioning the center of gravity within the base, eliminating the need for complex active stabilization systems while maintaining simplicity through passive gravitational balancing.
Solution Approach 2:
The patent optimizes the columnar member's length parameter to be greater than the first arm length, creating a specific geometric relationship that naturally stabilizes the center of gravity. This parameter change transforms the base structure into a self-stabilizing system where the extended columnar member's mass distribution automatically balances the robot during relocation without requiring additional complex mechanisms.

AI summary
A robot that includes a base that is provided with a flat installation surface member that is disposed on an installation target surface and a columnar member that extends upward from the installation surface member; and a first arm, one end of which is supported so as to be rotatable about a first horizontal axis located above the columnar member of the base and that has a motion range below the first horizontal axis. The columnar member has a length that is equal to or longer than the length of the first arm and has a uniform transverse sectional area that is the same as the first arm.
