Test Results & Release 7 by Jeffrey Johnson

This release includes the first physical test results of closed-loop control with Image Space Potential Fields. The test demonstrates a shared-autonomy control scheme that enforces collision avoidance behavior over an input global guidance behavior. The software contains primarily maintenance work and incremental improvements.

Sim Collaboration & Release 6 by Jeffrey Johnson

Maeve Automation has entered into a strategic alliance with Parallel Domain to explore simulation techniques for the development and testing of mobile navigation systems. The capabilities they have for procedural generation are pretty exciting and we are working on using them to demonstrate some of the capabilities of the Maeve navigation stack. Some preliminary results and a small test data set are included here in Release 6.

Image Space Potential Fields: Constant Size Environment Representation for Vision-based Subsumption Control Architectures by Jeffrey Johnson

This technical report presents an environment representation for use in vision-based navigation. The representation has two useful properties: 1) it has constant size, which can enable strong run-time guarantees to be made for control algorithms using it, and 2) it is structurally similar to a camera image space, which effectively allows control to operate in the sensor space rather than employing difficult, and often inaccurate, projections into a structurally different control space (e.g. Euclidean). The presented representation is intended to form the basis of a vision-based subsumption control architecture.

Release 5 by Jeffrey Johnson

The main component of this release is a prototype implementation of a monocular visual servoing controller based on Image Space Potential (ISP) fields. ISP field are designed to implement a subsumption control architecture that allows arbitrarily many layers of annotated camera data to be fused together in a coherent control space.

Release 4 by Jeffrey Johnson

The main component of this release is a basic implementation of Composite Image Space Potential (CISP) fields. These are scalar fields that represent environment information as specially defined potential fields, and is work related to the material Maeve will be presenting at IROS.

See you at IROS & ROSCon in Vancouver! by Jeffrey Johnson

Maeve will have poster presentation at IROS, as well as a paper in the Workshop on Planning, Perception and Navigation for Intelligent Vehicles. An attempt will be made to give a lightning talk at ROSCon, provided the scheduling works out. Further details will be posted closer to the events.

Release 2 by Jeffrey Johnson

The second release of our ROS open source development packages adds control support for the Donkey Car robot platform. In addition, there is now an image of Ubuntu Mate 16.04.2 LTS for Raspberry Pi that is pre-loaded with ROS Kinetic, Maeve development libraries, and configured for the Donkey Car platform.
