Gripper and EOAT Engineering Calculator
A browser engineering tool combining finger structure, retention, force/pressure, positive stops, stroke, payload, wrist moment, EOAT mass, and center of gravity.
MY FOCUSIntegrated mechanical checks and configuration logic into one review workflow.
ENGINEERING VALUE
Shows cross-disciplinary integration of fixture, pneumatics, structure, and robot payload considerations.
ENGINEERING STUDY / FIXTUREJS—02
Engineering concept illustration.
01 / THE PROBLEM
The engineering challenge.
End-of-arm tooling decisions require several linked mechanical checks that are easy to evaluate inconsistently in separate worksheets.
02 / CONSTRAINTS
What the solution must consider.
- Catalog ratings and simplified structural equations cannot substitute for final vendor confirmation, detailed stress analysis, or robot-system validation.
03 / ENGINEERING APPROACH
Reasoning before geometry.
01
Engineering method
Expose linked inputs and keep pass/fail checks near their governing assumptions so users can see which constraint controls.
02
Workflow features
Finger structural model; Retention and force window; Positive-stop selection; Robot payload and wrist moment; EOAT mass/COG; Automated checks and limitations.
04 / DESIGN & IMPLEMENTATION
Connecting intent to execution.
Version 4 combines gripper, pneumatic, structural and robot-payload considerations with editable configuration inputs.
- Finger structural model
- Retention and force window
- Positive-stop selection
- Robot payload and wrist moment
- EOAT mass/COG
- Automated checks and limitations
05 / VALIDATION
The checks behind the design.
Design study
Sizing uses catalog data and simplified structural relationships. Vendor ratings, robot-system behavior and the final load cases require application-specific confirmation.
06 / OUTCOME
The value of the work.
Shows cross-disciplinary integration of fixture, pneumatics, structure, and robot payload considerations.
THE ENGINEERING PRINCIPLE
Connect constraints to the physical load path.
A useful workholding design balances location, support, clamping, access and distortion. Documenting these decisions gives manufacturing and quality teams a basis for reviewing the setup.
A question for a technical conversation
How would you verify location, contact and repeatability before production release?
