Robot Reach Calculator
Calculate robot workspace and reach
With this tool you calculate workspace, reach and kinematics of serial robot arms from joint and link lengths. The results are shown graphically and can be used for robotics, automation and engineering projects.
The calculator supports planning of robot cells, selection of suitable robots and understanding of 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 applications:
- Robotics and automation
- Planning of manufacturing cells
- Feasibility studies
- Comparison of different robot kinematics
- Education and training
- Preparation of ROS projects
How does the calculator work?
- Set the number of joints
- Enter the link lengths
- Optionally define joint limits
- Start the calculation
- Analyse workspace and reach
- Check results and kinematics
The calculation runs directly in the browser and provides a graphical view of the reachable workspace.
What results are output?
- 3D view of the robot arm
- Visualisation of the workspace
- 2D projection of the work area
- maximum reach
- minimum reach
- DH parameter table
- Forward kinematics
- Joint angles and positions
- URDF export for ROS
Typical applications
- Planning of robot workstations
- Gripper and tool sizing
- Reach analysis
- Collision considerations
- Layout planning of production plants
- Simulation and virtual commissioning
Benefits of the Robot Reach Calculator
- fast calculation without a CAD system
- direct use in the browser
- graphical display of the workspace
- support for ROS workflows
- suitable for training and engineering
Technical notes
Serial robot arms with rotary joints are modelled. The calculation is based on standardised DH parameters and can be used for typical industrial and training applications.
All calculations are performed locally in the browser. For ROS-compatible models, an optional URDF export can be generated.
