Question 1

Should I use MoveIt or ROS2 control for my robot arm?

Accepted Answer

MoveIt is a higher-level framework for motion planning and manipulation, while ROS2 control focuses on low-level joint control. For complex tasks like pick-and-place, MoveIt is preferable; for simple actuator control, ROS2 control might suffice, and they often integrate together.

Question 2

How to set up MoveIt for a custom robot arm?

Accepted Answer

Use the MoveIt Setup Assistant, a graphical tool mentioned in the README, to generate configuration files like URDF and SRDF. This involves defining robot kinematics, joints, and collision models, but manual tweaking may still be required for optimal performance.

Question 3

What robots are compatible with MoveIt?

Accepted Answer

MoveIt is compatible with a wide range of robots, including popular models from Universal Robots, KUKA, and Franka Emika. The community maintains pre-configured setups, and the Setup Assistant helps create custom configurations for any ROS-supported robot.

Question 4

Is MoveIt suitable for real-time industrial applications?

Accepted Answer

MoveIt can handle near-real-time planning, but for hard real-time requirements, consider using it with ROS2 and real-time kernels. Latency from ROS messaging might still be a concern in high-speed or safety-critical environments.

Question 5

How does MoveIt handle perception for dynamic environments?

Accepted Answer

MoveIt integrates with 3D sensors and occupancy maps through packages like moveit_ros_perception, allowing it to update the planning scene dynamically for collision avoidance, as noted in the key features.

Question 6

Can I use MoveIt without ROS?

Accepted Answer

No, MoveIt is tightly coupled with ROS, as stated in the description. For non-ROS projects, you would need to bridge to ROS or consider alternative frameworks, which adds complexity and may not be practical.
