MOBILE BODY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240326606 titled 'MOBILE BODY
The abstract describes a patent application for a mobile body with left and right driving wheels, swivel casters, and a controller for driving and controlling the movement of the body. The controller includes units for estimating front-rear distances, calculating stability limit velocity, and controlling the drive unit to maintain stability.
- The mobile body includes left and right driving wheels, swivel casters, and a controller.
- The controller estimates front-rear distances and calculates stability limit velocity based on various factors.
- The driving control unit ensures the velocity of the mobile body does not exceed the stability limit velocity.
Potential Applications: - Autonomous vehicles - Industrial robots - Material handling equipment
Problems Solved: - Ensuring stability and control of mobile bodies - Preventing accidents due to excessive speed
Benefits: - Improved safety in mobile operations - Enhanced maneuverability and control - Efficient movement in various environments
Commercial Applications: Title: "Smart Mobile Body Control System for Enhanced Stability" This technology can be used in autonomous vehicles, industrial robots, and material handling equipment to improve safety and efficiency in various operations.
Questions about the technology: 1. How does the controller estimate front-rear distances for maintaining stability? - The estimation unit calculates the front-rear distance between the ground contact position of the swivel caster and the center of gravity to determine stability.
2. What factors are considered in calculating the stability limit velocity? - The stability limit velocity is based on the front-rear distance, cornering power of the driving wheel and swivel caster, and other calculation conditions.
Original Abstract Submitted
a mobile body includes: left and right driving wheels provided on a main body; a drive unit for driving each of the driving wheels; left and right swivel casters; and a controller for controlling the drive unit. the controller includes: an estimation unit for estimating a front-rear distance between a ground contact position of the swivel caster and a center of gravity; a limit velocity calculation unit for calculating a stability limit velocity based on the front-rear distance estimated by the estimation unit, a front-rear distance between a ground contact position of the driving wheel and the center of gravity, a cornering power of the driving wheel, and a cornering power of the swivel caster when a predetermined calculation condition is satisfied; and a driving control unit for controlling the drive unit such that a velocity of the mobile body is less than or equal to the stability limit velocity.
