Advanced BIT* (ABIT*): Sampling-Based Planning with Advanced Graph-Search Techniques

Advanced BIT* (ABIT*): Sampling-Based Planning with Advanced Graph-Search Techniques Path planning is the problem of finding a continuous sequence of valid states from a start to a goal specification. Popular approaches in robotics include graph-based searches, such as A* [1], and sampling-based planners, such as Rapidly-exploring Random Trees (RRT) [2]. Both graph- and sampling-based approaches [...]

Learning from Demonstration with Minimal Human Effort

Learning from demonstration and reinforcement learning have been applied to many difficult problems in sequential decision making and control. In most settings, it is assumed that the demonstrations available are fixed. In this work, we consider learning from demonstration in the context of shared autonomy...

Introspective Radar Odometry

How do we know when we don’t know? This is an important question to answer in any situation where we need to navigate through our surroundings, and something any autonomous mobile robot needs to know too. We discuss this introspection capability and its importance to our radar-based navigation algorithms [...]

ORI Volunteer at St Paul’s Girls’ School as Robotics Mentor

Over the past few months, one of our 2nd year DPhil students, Mark Finean, has been volunteering as a robotics mentor to a group of girls pursuing their A levels at St Paul’s Girls’ School (SPGS) in London. For a school project, they wished to learn more about robots and investigate how they could [...]

Laser Localization

What's the problem? Motivation This is a blog post designed for non-technical people to understand the basics of localization. As such we are not going to touch any code but rather interactively present you with examples how these systems run and what makes them tick. Localization is an essential [...]

What about radar?

Radar is awesome. When most people think of radar, they imagine a line sweeping around an old CRT display with its characteristic green hue - interrupted by approaching aircraft, or perhaps distant ships over the horizon. While our experience with cameras and GPS has remained up-to-date as hardware has [...]
