Robotic Simulation with Webots and Forester on Rust

Intro: What is what

Forester is a powerful framework built for behavior trees. It simplifies complex BT workflows by combining tasks and offers flexibility in the execution of complex flows (timing, location). Great for AI in games, robotics, and workflow engines — and written in Rust.

Webots is a robot simulation platform whose core functionality revolves around creating virtual robots and simulating their behavior in realistic environments.

Forester: A Line-Sorting Warm-Up Example

Intro

Behavior trees are a mathematical model that helps execute complex, multi-component workflows.

Forester is an orchestration framework that uses behavior trees as a core concept, providing a layer above them that includes a DSL for writing trees, synchronization and asynchronous mechanisms, and more.

The interesting part is how to apply it to real problems in robotics or game design. This article gives a warm-up artificial example.

Forester: Daemons for the Good

Intro

Forester is an orchestration framework that relies on behavior trees as a core concept. On top of the trees, Forester provides a set of tools to make behavior trees more flexible and powerful, including higher-order trees, tree trimming, remote actions, and more.

Behavior trees are a powerful tool, providing a solid foundation for a wide range of tasks.

But the framework can’t operate in a vacuum. The modern infrastructure of robotic clusters is a multilayer pie where Forester can be the icing but not a replacement for solid, fast hardware processes or distributed data logistics systems.

Forester: Export to ROS Nav2

Intro

Forester is an orchestration framework with behavior trees at its core. On top of the trees, Forester provides a set of tools to make behavior trees more flexible and powerful, including higher-order trees, tree trimming, remote actions, and more.

Behavior trees are a powerful tool, providing a solid foundation for a wide range of tasks. It’s no surprise that behavior trees are widely used in robotics.

Forester: Remote Actions to the Rescue!

Intro

Behavior trees are a mathematical model used to execute complex flows. Forester is an orchestration framework that operates on top of behavior trees, providing a clean and simple way to run tasks that implement the behavior tree concept out of the box.

Although the core concept under the hood is behavior trees, the framework also provides a DSL called f-tree, which compiles into the trees.

Forester: Changing the Runtime Tree on the Fly — Trimming

Intro

Today, industrial robots can tackle high-complexity tasks in controlled environments, which is nothing short of inspiring.

But there’s a small rub. Modern industrial applications increasingly require robots to act and orient themselves in unpredictable surroundings as well. One common way to handle this is to control the robot with a reactive policy such as behavior trees (BTs).

Forester is an orchestration framework that operates on top of behavior trees, enabling the construction of an orchestration process from scratch. It provides a clean and straightforward way to run tasks that implement the behavior tree concept out of the box.
