Scikit-bot is a robotics library that aims to address the large heterogeneity of code in the robotics community by providing a selection of commonly used algorithms and functions in an easy access manner. It focusses on begin easy to use and on enabling rapid prototyping.
Scikit-bot includes functions for coordinate transformations and projections, functions for trajectory generation and kinematics, and many more, yet, it is not a simulator or robotics framework. It is a library meant to complement existing tools. With scikit-bot, you can quickly try things in python first, get it working, and then integrate it into your framework of choice; potentially, using one of our existing modules to interface with the framework, saving you more time.
Scikit-bot follows a python-first approach. Typically, robotics frameworks are written in plain C or C++ and, if it is possible to use via python, support is rudementary at best. In scikit-bot, python is a first-class citizen with the majority of the code being written in plain python. The rationale is that the majority of work done in robotics is prototyping, and prototyping is much (much) faster in an interpreted language than a compiled one. It is significantly more efficient to write code that works first (leveraging pythons amazing debugging capabilities) and then optimize for speed, than it is to debug broken, fast code.
