Semi-Autonomous Vehicle Teleoperation Across Low-Bandwidth or High-Delay Transmission Links

چکیده
Guiding a remote vehicle when real time image transmission is not possible is an important problem in the field of teleoperation. In such a situation, it is impractical to put an operator behind a steering wheel and expect accurate steering. In semiautonomous teleoperation, an operator designates the path that the vehicle should follow in an image of the scene transmitted from the vehicle, and the vehicle autonomously follows this path. Previous techniques for semi-autonomous teleoperation require stereo image data, or inaccurately track paths on non-planar terrain. STRIPE is a method for accurate semi-autonomous teleoperation using monocular image data. By combining techniques in computer control, artificial intelligence, and intelligent user interfaces, we are designing a unique system for remote operation of a vehicle across low-bandwidth and high-delay transmission links.

متن کاملControl of a Semi-Autonomous UGV Using Lossy Low-Bandwidth Communication
This paper describes various mechanisms for supervisory remote operation of an UGV. Contrary to common Wi-Fi (IEEE 802.11) approaches our approach enables communication via a lossy low-bandwidth radio link. The mechanisms include the massive reduction of environmental sensor data for transmission to the operator. The vehicle itself is capable of semiautonomous control. Doing so, the operator is...
متن کاملSTRIPE: Supervised TeleRobotics Using Incremental Polygonal Earth Geometry
We present a method of semi-autonomous teleoperation of a vehicle which allows it to accurately traverse hilly terrain while communicating with the operator across a very low bandwidth link. The operator plots the vehicle’s chosen trajectory based on a single 2-D image, and the transformation of 2-D image points to 3-D world points is done in real time on the vehicle. Traditional flat-earth geo...
