Mobile Robot Cover Partition for Drip-Proof Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile robots used in factory production systems face challenges in reducing height while maintaining drip-proof specifications, especially in environments where cutting oil may adhere to them.
Innovation Solution
A mobile robot configuration with a linear motion shaft, movable body, cover, electric device unit, transport mechanism, and elevating mechanism, where the robot is housed within a cover with an opening facing process areas, and electric components are positioned to avoid oil exposure, allowing for reduced height and drip-proof operation.

1Length of moving object
If the mobile robot is designed with a compact structure to reduce height, then the size in height direction is reduced, but it becomes difficult to ensure drip-proof specifications for electric components
Solution Approach 1:
The patent positions electric components in the vertical dimension above the robot body, separating them from the oil-prone horizontal working area. This dimensional separation allows the robot to maintain a compact height while ensuring electric components remain above the oil level, achieving both size reduction and drip-proof protection.
Solution Approach 2:
The patent introduces a shield or cover as an intermediary structure that physically blocks cutting oil from reaching electric components. This mediator allows the robot to operate in oily environments while protecting sensitive electronics, resolving the contradiction between compact design and drip-proof requirements.
2Reliability
If electric components are positioned above the robot body to avoid oil exposure, then drip-proofness is achieved, but the device complexity increases
Solution Approach 1:
The shield or cover structure serves multiple functions: it acts as a protective barrier against oil, provides structural support for mounting electric components, and contributes to the overall robot housing. This multi-functionality reduces the need for additional separate protective structures, thereby limiting the increase in device complexity.

AI summary
A mobile robot includes an electric device unit disposed inside a cover and upward of a robot, and a transport mechanism disposed downward of the robot. An end part of a rotation shaft of a motor driving an arm portion of the robot faces downward. The cover includes a partition plate separating a first housing space in which the electric device unit is housed and a second housing space in which the robot is housed. The partition plate has a protrusion protruding into the first housing space. The protrusion provides a motor housing space in the second housing space. At least one part of the first motor is housed in the motor housing space when a base of the robot is elevated to an uppermost position.
