Walksylib — Extended

WalkSylib is a lightweight, command-line tool (or library) for creating, managing, and analyzing walking routes and GPS traces, focused on simplicity, minimal dependencies, and privacy. It supports importing/exporting GPX/GeoJSON, filtering and smoothing tracks, calculating route stats (distance, elevation gain/loss, pace), and generating shareable maps without sending data to external servers.

For robotics teams, Walksylib drops directly into the Nav2 stack. It publishes a walksylib/gait_cmd message that overrides the standard cmd_vel. Instead of just linear and angular velocity, it sends joint-level target angles for 22 degrees of freedom in the lower body, allowing your robot to walk with a natural hip roll. walksylib

Most libraries fail on stairs, curbs, or gravel. Walksylib utilizes a terrain-sampling filter. It reads floor materials (via semantic segmentation input) and adjusts the Center of Mass (CoM) trajectory in real-time. On gravel, it increases step frequency and reduces step length; on stairs, it initiates a "swing-foot clearance" protocol. WalkSylib is a lightweight, command-line tool (or library)

At its core, Walksylib (pronounced "walk-sigh-lib") is an open-source middleware library designed to standardize pedestrian locomotion data for synthetic and real-world environments. The name is a portmanteau of "Walking" and "Synthesis Library." It acts as a universal translator between raw motion capture data and robotic control systems (ROS/ROS2), game engines (Unity/Unreal), and urban simulation tools (SUMO, AnyLogic).

Unlike traditional pathfinding libraries (like A* or RRT) that assume ideal, frictionless movement, Walksylib focuses on the imperfections of human gait and pedestrian decision-making. It accounts for hesitation, step asymmetry, gaze-based steering, and social collision avoidance (a more advanced take on the Reciprocal Velocity Obstacle algorithm).
