Important Note (October, 2016)

Drake is currently undergoing a major renovation, with all of the core libraries moving into C++. The examples will move and the existing APIs will change. During this time, we recommend that users either engage deeply (contributing examples/tests which provide coverage of your use cases) or wait for a few months until the APIs have stabilized. For a stable release, consider checking out this SHA.

This change is fantastically exciting – Drake is becoming a mature and powerful tool. Thank you for your patience.

Overview

Drake (“dragon” in Middle English) is a C++ toolbox started by the Robot Locomotion Group at the MIT Computer Science and Artificial Intelligence Lab (CSAIL). The development team has now grown significantly, with core development led by the Toyota Research Institute. It is a collection of tools for analyzing the dynamics of our robots and building control systems for them, with a heavy emphasis on optimization-based design/analysis.

While there are an increasing number of simulation tools available for robotics, most of them function like a black box: commands go in, sensors come out. Drake aims to simulate even very complex dynamics of robots (e.g. including friction, contact, aerodynamics, ...), but always with an emphasis on exposing the structure in the governing equations (sparsity, analytical gradients, polynomial structure, uncertainty quantification, ...) and making this information available for advanced planning, control, and analysis algorithms. Drake provides interfaces to high-level languages (MATLAB, Python, ...) to enable rapid-prototyping of new algorithms, and also aims to provide solid open-source implementations for many state-of-the-art algorithms. Finally, we hope Drake provides many compelling examples that can help people get started and provide much needed benchmarks. We are excited to accept user contributions to improve the coverage.

Here is a quick summary of capabilities:

Most of these models/tools are described in the companion textbook from an MIT course/MOOC. We’ve also recently started populating the Drake Gallery (contributions welcome!).

We hope you find this tool useful. Please engage us via github issues with comments, questions, success stories, and frustrations. And please contribute your best bug fixes, features, and examples!
