ROBOT CLEANER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17913122 titled 'ROBOT CLEANER
Simplified Explanation
The abstract describes a robot cleaner with a shielding module that improves collision detection using a cliff sensor. Here are the key points:
- The robot cleaner has a shielding module under its body.
- The shielding module includes a cam and a hiding plate that rotate together.
- The distance between the center of the hiding plate and the rotating shaft is longer than the distance between a contact point on the cam surface and the rotating shaft.
- A guide protrusion on the bumper is in contact with the cam surface at the contact point.
- This design allows the hiding plate, which hides the cliff sensor, to rotate at a faster speed than the bumper's movement.
- The faster rotation of the hiding plate improves the sensitivity of collision detection using the cliff sensor.
Potential applications of this technology:
- Robotic vacuum cleaners or floor cleaners
- Autonomous cleaning robots in commercial or industrial settings
- Robotic lawn mowers
Problems solved by this technology:
- Improves collision detection by using a cliff sensor
- Enhances the sensitivity of collision detection by increasing the speed of the hiding plate rotation
Benefits of this technology:
- More accurate collision detection, reducing the risk of damage to the robot or obstacles
- Improved efficiency in cleaning or mowing tasks by avoiding collisions
- Enhanced safety by preventing the robot from falling off cliffs or stairs
Original Abstract Submitted
A robot cleaner having a shielding module provided under a cleaner body is provided. The shielding module includes a cam and a hiding plate which rotate with the same phase angle about a same rotating shaft. The distance between the center of the hiding plate and the center of the rotating shaft is longer than the distance between a contact point on a cam surface of the cam and the center of the rotating shaft. A guide protrusion of a bumper is in contact with the cam surface at the contact point. Therefore, the rotation movement speed of the hiding plate which rotates to hide a cliff sensor is much faster than the inner movement speed of the bumper, thereby improving sensitivity to the detection of a collision between the bumper and an obstacle by using the cliff sensor.
