The planning framework (Tesseract) was designed to be light weight, limiting the number of dependencies, mainly only using standard libraries like, eigen, boost, orocos and to the packages below. The core packages are ROS agnostic and have full python support.

Tesseract Setup Wizard and Visualization Tools

Python Installation

A self contained Tesseract Python package is available on PyPI for Windows 10+, Ubuntu 20.04, and Ubuntu 22.04. This package contains Tesseract, Tesseract Planning, and all dependencies in the single package. Packages are available for Python 3.7 - 3.10.

To install on Windows:

python -m pip install tesseract-robotics tesseract-robotics-viewer

To install on Ubuntu 20.04 and Ubuntu 22.04:

sudo apt install python3-pip python3-numpy
# The supplied version of pip on Ubuntu 20.04 is too old for manylinux_2_31, upgrade pip
python3 -m pip install -U pip
python3 -m pip install --user  tesseract_robotics tesseract_robotics_viewer

Tesseract Core Packages

• tesseract – This is the main class that manages the major component Environment, Forward Kinematics, Inverse Kinematics and loading from various data.
• tesseract_command_language – This package contains a generic command language to support motion and process planning similar to industrial teach pendants
• tesseract_collision – This package contains a common interface for collision checking prividing several implementation of a Bullet collision library and FCL collision library. It includes both continuous and discrete collision checking for convex-convex, convex-concave and concave-concave shapes.
• tesseract_common – This package contains common functionality needed by the majority of the packages.
• tesseract_environment – This package contains the Tesseract Environment which provides functionality to add,remove,move and modify links and joint. It also manages adding object to the contact managers and provides the ability.
• tesseract_geometry – This package contains geometry types used by Tesseract including primitive shapes, mesh, convex hull mesh, octomap and signed distance field.
• tesseract_kinematics – This package contains a common interface for Forward and Inverse kinematics for Chains, Trees and Graphs including implementation using KDL and OPW Kinematics.
• tesseract_scene_graph – This package contains the scene graph which is the data structure used to manage the connectivity of objects in the environment. It inherits from boost graph and provides addition functionality for adding,removing and modifying Links and Joints along with search implementation.
• tesseract_support – This package contains support data used for unit tests and examples throughout Tesseract.
• tesseract_visualization – This package contains visualization utilities and libraries.
