Robot Reach Calculator

Calculate robot workspace and reach

With this tool, you can calculate the workspace, reach and kinematics of serial robot arms based on joint and link lengths. The results are visualised and can be used for robotics, automation and engineering projects.

The calculator supports planning robot cells, selecting suitable robots and understanding kinematic relationships.

What is the Robot Reach Calculator used for?

When planning robot systems, it is important to know which positions a robot can reach and how large its workspace is.

Typical use cases:

• Robotics and automation
• Planning manufacturing cells
• Feasibility studies
• Comparison of robot kinematics
• Education and training
• Preparing ROS projects

How does the calculator work?

1. Set the number of joints
2. Enter link lengths
3. Optionally define joint limits
4. Start calculation
5. Analyse workspace and reach
6. Review results and kinematics

The calculation runs directly in the browser and provides a graphical representation of the reachable workspace.

Which results are output?

• 3D representation of the robot arm
• Workspace visualisation
• 2D projection of the workspace
• maximum reach
• minimum reach
• DH parameter table
• Forward kinematics
• Joint angles and positions
• URDF export for ROS

Typical applications

• Planning robot workstations
• Gripper and tool sizing
• Reach analysis
• Collision considerations
• Layout planning of production facilities
• Simulation and virtual commissioning

Benefits of the Robot Reach Calculator

• fast calculation without a CAD system
• direct use in the browser
• graphical workspace visualisation
• support for ROS workflows
• suitable for education and engineering

Technical notes

Serial robot arms with revolute joints are modelled. The calculation is based on standard DH parameters and can be used for typical industrial and educational applications.

All calculations are performed locally in the browser. For ROS-compatible models, an optional URDF export can be generated.
