Tip:Use this during early cell layout before opening RobotStudio or RoboDK. Spherical reach is a first-pass check — verify critical poses with your robot vendor's kinematics tools.

What it is, when to use it, formulas, and common questions
What is this?
Checks whether a work point falls inside an industrial robot's reach envelope and shows margin to the limit.
When do engineers use it?
Use during cell layout — before committing to robot model, fixture position, or conveyor placement.
Formula
Reachable if √(X² + Y² + Z²) ≤ max reach Margin = max reach − distance
Example
900 mm reach robot, work point at (600, 400, 200) mm → distance ≈ 761 mm, ~139 mm margin (reachable).
FAQ
- Is this a full kinematics check?
- This uses spherical reach (max distance from base). Joint limits and orientation constraints are not modeled — verify critical poses in your robot vendor software.
- Does TCP offset change reach?
- Yes. A long tool extends the point you care about beyond the flange. The envelope here is flange-centric; add tool length mentally or in vendor software for tight cells.
- What margin should I keep?
- Leave tens of millimeters at least, more if the part or fixture has stack-up. Working at the sphere limit often hits wrist singularities or joint limits even when the distance looks OK.
- Can I compare two robot models?
- Change the max-reach value to each model’s rated reach and drag the same work point. This is a first-pass layout check, not a replacement for a full kinematic simulation.
