Segmented Robot Assembly for In-Wall Conduit Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing electrical systems in existing walls require multiple access holes and significant invasive work, making it difficult to modify or add new electrical components without damaging the structure.
Innovation Solution
A robot with a linear and rotational actuator assembly that can maneuver through confined spaces, allowing for drilling and conduit installation without cutting holes in the walls, using a single motor to rotate and extend an outer body relative to an inner body, and a mechanism to lock out rotational motion during drilling.

1Ease of manufacture
If multiple access holes are cut in the wall face to install electrical systems in existing walls, then the installation can be completed, but the wall structure is significantly damaged and the work becomes invasive
Solution Approach 1:
The wall is divided into multiple segments or zones defined by the grid of access holes. Each hole serves as an independent access point for installing electrical components within specific wall segments, allowing localized work without compromising the entire wall structure.
Solution Approach 2:
Access holes are strategically planned and positioned in advance before installation begins. The grid pattern is predetermined based on the electrical system layout requirements, allowing for minimal and precise wall intervention rather than reactive drilling during installation.
2Device complexity
If a single motor is used to both rotate and extend the outer body, then the device complexity is reduced, but the motor must perform multiple functions simultaneously
Solution Approach 1:
The single motor integrates both rotational actuation and linear extension functions within one device. Through mechanical coupling mechanisms, the motor's rotational output is converted to produce both the rotation of the outer body and its simultaneous linear extension along the central longitudinal axis.
Solution Approach 2:
The motor is designed as a universal actuator capable of performing multiple functions: generating rotational motion for the outer body, converting that rotation into linear extension through mechanical linkages, and potentially providing locking functions. This multi-functional design eliminates the need for separate motors for each degree of freedom.

AI summary
A robot includes a first link having a first longitudinal passage extending therethrough and a second link having a second longitudinal passage extending therethrough. The second link is releasably engageable with the first link. The first longitudinal passage is in communication with the second longitudinal passage and each of the first longitudinal passage and the second longitudinal passage are configured to allow a common conduit to extend therethrough.
