OpenRAVE

OpenRAVE is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand OpenRAVE rather than just read about it. In short: Open Robotics Automation Virtual Environment (OpenRAVE) provides an environment for testing, developing, and deploying motion planning algorithms in real-world robotics applications. The main focus is on simulation and analysis of kinematic and geometric information related to motion planning.

Key takeaways

OpenRAVE belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OpenRAVE to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OpenRAVE from memory before moving on to harder problems.

Reference excerpt

Open Robotics Automation Virtual Environment (OpenRAVE) provides an environment for testing, developing, and deploying motion planning algorithms in real-world robotics applications. The main focus is on simulation and analysis of kinematic and geometric information related to motion planning. OpenRAVE's stand-alone nature allows it to be easily integrated into existing robotics systems. It provides many command-line tools to work with robots and planners, and the run-time core is small enough to be used inside controllers and bigger frameworks.

Components

IKFast IKFast is a compiler for inverse kinematics. Unlike most inverse kinematics solvers, IKFast can analytically solve the kinematics equations of any complex kinematics chain, and generate language-specific files (like C++) for later use. The end result is extremely stable solutions that can run as fast as 5 microseconds on recent processors.

COLLADA

OpenRAVE supports the COLLADA 1.5 file format for specifying robots and adds its own set of robot-specific extensions. The robot extensions include:

manipulators sensors planning-specific parameters

Motion planning

The core of OpenRAVE design focuses on offering interfaces and implementations of motion planning algorithms. Most of the planning algorithm implementations are for robot arms and use sampling to explore the task configuration spaces.

Applications An important target application is industrial robotics automation. OpenRAVE's main focus is to increase the reliability of motion planning systems to make integration easy.

History OpenRAVE was founded by Rosen Diankov at the Quality of Life Technology Center in the Carnegie Mellon University Robotics Institute. It was inspired from the RAVE simulator James Kuffner had started developing in 1995 and used for a lot of his experiments. The OpenRAVE project was started in 2006 and started out as a complete rewrite of RAVE to support plugins. It quickly diverged into its own architecture concept and started being supported by many robotics researchers throughout the world. After earning his PhD from the Robotics Institute in August 2010, Rosen Diankov became a postdoc at the JSK Robotics Lab at University of Tokyo where OpenRAVE is currently being maintained. Rosen Diankov is still the active maintainer of OpenRAVE.

Worked examples

Example 1 — a first encounter with OpenRAVE

Start with the simplest possible case. Write down what OpenRAVE claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OpenRAVE before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OpenRAVE ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OpenRAVE

In research: OpenRAVE appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses OpenRAVE in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: OpenRAVE is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2006 in robotics, 2006 software, Robotics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for OpenRAVE outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is OpenRAVE in simple terms?

Why does OpenRAVE matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OpenRAVE?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
