Ruckig is a motion planning library for robots and industrial machines. Its focus is not on being a complete robotics platform, but on “online trajectory generation”: calculating trajectories in real time inside a control loop based on the current state, target state, and velocity, acceleration, and jerk constraints. The page highlights that its computation time is typically below 1ms and that it can run in control cycles as low as 250µs, making it suitable for motion-control scenarios with demanding real-time requirements.
Its main strength is jerk-constrained trajectory generation. It can plan from arbitrary initial position, velocity, and acceleration states to a target state, and supports multi-axis time synchronization so that multiple axes reach the target simultaneously or achieve linear motion. It also provides a velocity-control interface, which is useful for control logic such as safe stops. The page also mentions features such as position limits, intermediate waypoints, tracking moving signals, directional velocity/acceleration limits, and minimum trajectory duration, but the boundary between some advanced features and the Pro version should be further confirmed based on licensing.
Ruckig Community Version is open source under the MIT license, making it suitable for research, prototyping, and initial integration in commercial projects. The page states that the Community version supports C++20 and Python 3.8, while the Pro version supports C++03 and Python 3.8, which is more convenient for integration with legacy industrial control code. It emphasizes a simple API that can be embedded directly into the real-time control loop of a robot or machine, but the page does not specify concrete ecosystem integrations such as ROS or MoveIt.
In terms of pricing, the Community version is open source and free. Pro Version provides new features, consulting, integration, and long-term support, but no public pricing is listed, so users need to contact the vendor. For industrial projects, this kind of professional support may be more important than the library itself, especially when hard real-time behavior, numerical robustness, and safe shutdown requirements are involved.
Its advantages include strong real-time performance, comprehensive kinematic constraints, a friendly open-source license, and support from academic publications. Its limitations are that it focuses on trajectory generation and does not replace full motion planning, simulation, or robotics middleware. The cost and licensing details of the Pro version are not transparent, and Chinese-language resources or a domestic ecosystem are not evident. It is suitable for teams working on robot control, CNC, visual servoing, obstacle avoidance, multi-axis synchronization, and similar areas.
The crawled text does not provide information on access from mainland China, payment, or local support, so access status is unknown. If network or procurement constraints apply, alternatives such as MoveIt, Reflexxes, TOPP-RA, and Drake can be evaluated.
