A lightweight, accurate and robust monocular visual inertial odometry based on Multi-State Constraint Kalman Filter.

The ultimate distributed MQTT broker. Handles 100M+ connections and 10M msg/sec with ease. Built on Kafka to provide industrial-grade persistence and eliminate data loss.

Turn Amazon Echos (Echo Dot 3, Echo Dot 2, Echo 2) into local Home Assistant voice satellites. Keeps Amazon's mic processing and wake word engine, replaces Alexa with a small C daemon speaking ESPHome or Wyoming. Multiroom music via Music Assistant, Bluetooth speaker and proxy, no cloud.

RBDL is a C++ library that contains some essential and efficient rigid body dynamics algorithms such as the Articulated Body Algorithm (ABA) for forward dynamics, Recursive Newton-Euler Algorithm (RNEA) for inverse dynamics, the Composite Rigid Body Algorithm (CRBA) for the efficient computation of the joint space inertia matrix and is also able to compute forward dynamics with external contact constraints and collision impulses. Furthermore it has some basic support for forward and inverse kinematics.
