Planetary Surface Exploration Using a Network of Reusable Paths: a Paradigm for Parallel Science Investigations
نویسندگان
چکیده
A network of reusable paths (NRP) allows for a new approach to planetary surface exploration using a mobile robot. NRP gives the robot the ability to accurately return to any previously visited point. This allows missionlevel improvements by enabling parallel exploration of scientific targets. NRP would be particularly useful for sample-return missions to the Moon or Mars. The approach was tested in a mock Lunar sample-return mission near the impact crater located in Sudbury, Ontario, Canada. There, NRP enabled nearly twice as many sites to be investigated as compared to a serial approach to exploration. In this mock mission, the robot drove more than 3.9 km, allowing for in situ analysis and sample collection and return at many sites.

Planning using a Network of Reusable Paths: A Physical Embodiment of a Rapidly Exploring Random Tree
Growing a network of reusable paths is a novel approach to navigation that allows a mobile robot to autonomously seek distant goals in unmapped, GPS-denied environments, which may make it particularly well-suited to rovers used for planetary exploration. A network of reusable paths is an extension to visualteach-and-repeat systems; instead of a simple chain of poses, there is an arbitrary netwo...
متن کاملNavigation of a Mobile Robot Using Virtual Potential Field and Artificial Neural Network
Mobile robot navigation is one of the basic problems in robotics. In this paper, a new approach is proposed for autonomous mobile robot navigation in an unknown environment. The proposed approach is based on learning virtual parallel paths that propel the mobile robot toward the track using a multi-layer, feed-forward neural network. For training, a human operator navigates the mobile robot in ...
متن کاملTowards Autonomous Mobile Robots for the Exploration of Steep Terrain
Steep, natural terrain offers excellent opportunities for scientific investigations into the composition and history of Mars and other planetary bodies. In this paper, we present a prototype tethered robot, vScout (vertical scout), capable of operating in steep, rugged terrain. The primary purpose of this vehicle is to support field geologists conducting research on cliffs, in canyons, and on c...
متن کاملOptimization of the Cost Function in the Drilling of Oil Well Network by Balas Algorithm
The most costly operation in the oil exploration is the well network drilling. One of the most effective ways to reduce the cost of drilling networks is decreasing the number of the required wells by selecting the optimum situation of the rig placement. In this paper, Balas algorithm is used as a model for optimizing the cost function in oil well network, where the vertical and directional dril...
متن کاملPlace Revisiting for Planetary Rovers: An Enabling Technology and Field Testing of Three Mission Concepts
Planetary rovers to date have been operated mainly in a serial mode; they are driven from one place to the next, away from the lander, and seldom return to previously visited places. We have been developing a visual navigation technique, called network of reusable paths (NRP), that can be thought of as a low-computational-cost version of simultaneous localization and mapping coupled to a path-t...
