EOAT Weight with gripper or vacuum cup assembly weight of 10 lb: a worked example
This scenario runs the eoat weight calculation on the strong side: gripper or vacuum cup assembly weight of 10 lb, with every other input held at its documented default. Use it during EOAT design or robot sizing so total mass at the wrist is on one line item before cross-checking against rated robot payload.
The inputs for this scenario
- Gripper or vacuum cup assembly weight: 10 lb (raised for this scenario; the documented default is 4)
- Jaws, fingers, or tool plate weight: 3 lb (unchanged)
- Sensors, cables, and dress pack weight: 1.5 lb (unchanged)
- Tool changer or quick-change weight: 1.5 lb (unchanged)
Working through the calculation
- Applying the documented formula (Total EOAT weight = sum of gripper, jaws, sensors, and tool changer weights) to the inputs above produces each figure below.
- At this operating point the engine returns 16 lb for total eoat weight, the number this scenario is built around.
- At this operating point the engine returns 10 lb for element 1.
- At this operating point the engine returns 3 lb for element 2.
- At this operating point the engine returns 3 lb for element 3 + 4.
How this compares with the baseline
- Against the tool's baseline example, where gripper or vacuum cup assembly weight sits at 4 lb and the headline result is 10 lb, this scenario comes in 60% above the baseline at 16 lb.
- Use it when selecting a robot by payload, validating an EOAT design, or checking headroom before adding the workpiece weight. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
Results at a glance
- Total EOAT weight: 16 lb (headline result)
