Drake: Model-Based Design and Verification for Robotics
Drake is a powerful C++ toolbox developed by the Robot Locomotion Group at MIT's CSAIL, now significantly supported by the Toyota Research Institute. This toolbox is designed for analyzing robot dynamics and building control systems, with a strong emphasis on optimization-based design and analysis.
Overview
Drake, which means "dragon" in Middle English, is not just another simulation tool; it aims to provide a transparent view of the complex dynamics involved in robotics. Unlike many existing tools that operate as black boxes, Drake focuses on exposing the underlying structure of the governing equations, including aspects like sparsity, analytical gradients, and uncertainty quantification. This transparency is crucial for advanced planning, control, and analysis algorithms.
Core Features
1. Modeling Dynamical Systems
Drake allows users to model complex dynamical systems, making it easier to simulate real-world scenarios involving friction, contact, and aerodynamics.
2. API Tutorials
The toolbox comes with comprehensive API tutorials that guide users through solving mathematical programs and understanding multibody kinematics and dynamics.
3. Python Interface
Drake provides a Python interface for rapid prototyping of new algorithms, making it accessible for developers looking to innovate in robotics.
4. Open-Source Implementations
The team behind Drake is committed to providing solid open-source implementations of many state-of-the-art algorithms, encouraging community contributions to enhance the tool's capabilities.
Tutorials and Examples
Drake offers Python-based tutorials using Jupyter notebooks, which are highly recommended for users to view online. For those who prefer to run tutorials locally, instructions are available in the drake/tutorials/README.md file. Additionally, the source tree contains numerous use cases under drake/examples, and contributions to the Drake Gallery are welcomed.
Articles and Research
Drake has been featured in several articles that discuss its applications in model-based design and robotics, including:
- Drake: Model-based design in the age of robotics and machine learning
- Rethinking Contact Simulation for Robot Manipulation
- MIT Underactuated Robotics: Algorithms for Walking, Running, Swimming, Flying, and Manipulation
