Free tools for people building robots
No installs, no accounts. Utilities for ROS 2, URDF, kinematics, and more — runs entirely in your browser.
Every file you upload — maps, URDFs, meshes, param files — stays on your machine and is processed locally in your browser. Nothing is sent to a server; the server here only hosts this website. We only count anonymous page visits, without cookies.
All tools
URDF Visualizer
Drop in a URDF (+ meshes), see it rendered in 3D, inspect the TF tree, move joints, and catch setup issues before MoveIt does.
Quaternion ↔ Euler Converter
Live bidirectional conversion between quaternions and roll/pitch/yaw, using the ROS/URDF convention, with axis-angle, rotation matrix, and a 3D preview.
ROS2 QoS Calculator
Check whether a publisher and subscription QoS profile will actually connect — reliability, durability, deadline, and liveliness — using the same rules ROS2 itself does.
DH Parameter Calculator
Build a Denavit-Hartenberg parameter table and get forward kinematics — end-effector pose plus a live 3D chain preview.
Camera FOV & Calibration
Field of view / imaged coverage calculator, plus a print-accurate checkerboard/circle-grid calibration pattern generator and RGB-D alignment notes.
Coordinate Transform Calculator
Build a tree of coordinate frames and look up the transform between any two of them, or transform a point between frames.
ROS2 Launch File Generator
Generate a bringup launch file (Gazebo, RViz, robot_state_publisher) and a controller launch file with correctly exported Gazebo resource paths and sequenced controller spawners.
Nav2 Parameter Helper
Upload a map, set your robot's footprint, and tune AMCL/costmap parameters with a live inflation-layer preview.
MoveIt Configuration Helper
Sanity-check a MoveIt config package before running Setup Assistant — URDF crash causes, SRDF cross-validation, joint_limits.yaml, and controller config.
ROS 2 Devcontainer Generator
Pick your OS, ROS 2 distro and packages, and download a VS Code dev container with ROS 2, rosdep and working RViz / Gazebo GUI, on Linux, Windows or macOS.
