Gripper tab quick reference
About this topic
The Bravo gripper can pick up labware and move it from one location to another on the Bravo deck. If the Bravo Platform includes a gripper, you use the controls on the Gripper tab to configure the gripper movements.
The red Stop motors button does not perform an immediate stop. The Bravo head can continue to move in the same direction at the same speed. To perform an emergency stop, press the red button on the emergency-stop pendant.Procedures
You can use the Gripper tab to fine-tune the gripper movements using the following procedures:
Gripper Teaching area
Control or indicator | Description |
|---|---|
Labware | Specifies the labware to be used during a move operation as defined in the Labware Editor. |
Y offset | Specifies the offset to the y‑axis teachpoint at each location to center the gripper about the labware. |
Teach Y offset for gripper | Calculates the offset from the selected location teachpoint to where the gripper is and applies it as the y-offset. |
Approach height (mm) | Specifies a vertical offset (safe distance) above the labware. |
Approach | Moves the gripper to the specified approach height. |
Move | Moves the gripper to the teachpoint. |
Gripper Movement area
Control or indicator | Description |
|---|---|
Location A Pick A -> Place B | Specifies the origin and destination locations for the gripper to move the labware. |
Location B Pick B -> Place A | Specifies the origin and destination locations for the gripper to move the labware. |
Plate present in gripper | Lights when the plate sensor detects labware in the gripper. |
Jog Gripper Axes area
Control or indicator | Description |
|---|---|
Up -Zg, Down +Zg and increment (mm) list | Enables you to set an incremental distance (mm) to move the gripper, and then move it the specified distance along the Zg-axis. The gripper holds and moves labware along the Zg-axis from one location to another. |
Open -G, Close +G and increment (mm) list | Enables you to set an incremental distance (mm) to move the gripper, and then open or close it the specified amount. The gripper grips the labware along the G-axis. |
Dock gripper below head | Moves the gripper to the docked position to ensure that there is not interference when moving the liquid-handling head. |
Open gripper/Close gripper | Opens and closes the gripper, respectively. |
Speed | Sets the velocity of each gripper movement. For example, you might want to use a slow speed when setting the y offset. |
Zg-Axis and G-Axis areas
Control or indicator | Description |
|---|---|
Digital display (mm) | Displays the distance (mm) from the axis home position when the gripper is not in the home position. |
Home | Homes the gripper along the selected axis. |
Enable motor, Motor enabled | Enables or disables the motor for the selected axis. The Motor enabled indicator lights when the motor for the axis is turned on. |
