1. Introduction & Overview
What is MoveIt?

MoveIt is an open-source motion planning framework widely used in robotics for manipulation, navigation, motion planning, and control. Built on top of ROS (Robot Operating System), MoveIt simplifies the process of developing complex robotic behaviors like:
- Arm motion planning
- Grasping and manipulation
- Kinematics
- Collision checking
- Trajectory execution
It acts as a middleware that connects robot hardware with high-level applications, making it an essential tool in RobotOps (Robotics Operations).
History & Background
- 2012: First released under ROS, supported by Willow Garage.
- 2013–2017: Adopted by the community for robotic arms and industrial robots.
- 2018 onwards: Evolved into MoveIt 2, built for ROS 2 (more scalable, real-time ready).
- Supported by PickNik Robotics and large robotics community.
Why is it Relevant in RobotOps?
RobotOps focuses on managing, automating, and scaling robotic systems, similar to how DevOps works for software. MoveIt fits in because:
- Provides standardized tools for motion planning.
- Integrates seamlessly with CI/CD pipelines to test robot tasks before deployment.
- Helps with automation, reproducibility, and monitoring of robotic workflows.
2. Core Concepts & Terminology
Here are key MoveIt concepts every RobotOps engineer should know:
Term | Definition | Example Use |
---|---|---|
Motion Planning | Computing a safe path for robot joints to move between poses. | Moving a robotic arm from rest to pick an object. |
Kinematics | Mathematical relationship between robot’s joint angles and end-effector position. | Inverse kinematics used to calculate how an arm reaches a 3D point. |
Planning Scene | 3D environment model including robot, objects, and obstacles. | Collision-free path planning. |
Grasping | Picking, holding, and placing objects with end-effectors. | A robot picking items in a warehouse. |
Trajectory Execution | Sending planned motions to real robot controllers. | Executing a planned welding arm motion. |
How MoveIt fits into the RobotOps Lifecycle:
- Development: Create motion planning packages.
- Testing: Run simulations (Gazebo, RViz) before deploying.
- Deployment: Execute on real hardware.
- Monitoring: Log robot performance, detect collisions.
- Automation: Integrate into RobotOps CI/CD pipelines for updates.
3. Architecture & How It Works
Components of MoveIt
- Motion Planning Pipeline – OMPL (Open Motion Planning Library) & custom planners.
- Kinematics Plugins – For forward & inverse kinematics (KDL, IKFast).
- Collision Detection – Powered by FCL (Flexible Collision Library).
- Planning Scene – Maintains world and robot state.
- Trajectory Execution Manager – Communicates with robot controllers.
- RViz Integration – 3D visualization and debugging tool.
Internal Workflow
- Input: Goal (pose, trajectory, grasp) defined.
- Planning: Uses OMPL/other planners to compute path.
- Collision Check: Validates against planning scene.
- Trajectory Generation: Produces smooth robot path.
- Execution: Sends commands to robot hardware.
- Feedback Loop: Provides success/failure logs.

Integration with CI/CD & Cloud Tools
- CI/CD:
- Use GitHub Actions or GitLab CI to test motion planning packages.
- Run unit tests for IK solvers & planners in simulation.
- Cloud Integration:
- Deploy robot control pipelines on AWS RoboMaker or Azure Robotics.
- Monitor robots via Kubernetes or Prometheus exporters.
