This technology improves steering performance and driving stability by integrating real-time robot distance sensor (laser/ultrasonic) data with camera video feeds, overlaying them on a remote controller display, and providing force or haptic (vibration motor) feedback to the joystick based on obstacles in the robot's vicinity.
Existing remote control systems rely on narrow camera fields of view and 2D video, making it difficult to accurately perceive depth between the robot and obstacles. This often leads to reduced operational efficiency, such as collisions or the robot becoming stuck during non-line-of-sight navigation.
This technology visualizes obstacle distance information by overlaying it onto the video feed. If the operator attempts to steer toward an obstacle within a set safety distance, a feedback control mechanism triggers a vibration motor (haptic) or braking system (force feedback) in the joystick to alert the operator. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it enhances operability by providing wide-range situational awareness and haptic feedback, thereby reducing collisions and isolation in remote control scenarios.
