Frequently Asked Technical Questions

Z-Arm Series Robot Arm

Q1. Can the internal part of the robot arm be connected to the trachea?

Answer:  The internal of 2442/4160 series can take trachea or straight wire. 

Q2. Can the robot arm be installed upside down or horizontally?

Answer: Some robot arm models, such as 2442, support inverted installation, but do not support horizontal installation at the moment. 

Q3. Can the robot arm be controlled by PLC?

Answer: Since the protocol is not open to the public, it currently does not support the PLC to communicate with the robot arm directly. It can communicate with the arm’s standard host computer SCIC Studio or secondary development software to realize the control of the robot arm. The robot arm is equipped with a certain number of I /O interface which can carry out signal interaction.

Q4. Can the software terminal run on Android?

Answer: It is not currently supported. The standard host computer SCIC Studio can only run on Windows (7 or 10), but we provide a secondary development kit(SDK)on the Android system. Users can develop applications to control the arm according to their needs. 

Q5. Can one computer or industrial computer control multiple robot arms?

Answer: SCIC Studio supports independent control of multiple robot arms at the same time. You only need to create multiple workflows. A host IP can control up to 254 robot arms(same network segment). The actual situation is also related to the performance of the computer.

Q6. What languages does the SDK development kit support?

Answer: Currently supports C#, C++, Java, Labview, Python, and supports Windows, Linux, and Android systems. 

Q7. What is the role of server.exe in the SDK development kit?

Answer: server.exe is a server program, which is responsible for the transmission of data information between the robot arm and the user program.

Robotic Grippers

Q1. Can the robot arm be used with machine vision?

Answer: At present, the robot arm cannot directly cooperate with the vision. The user can communicate with SCIC Studio or secondary developed software to receive the visual related data to control the robot arm. In addition, the SCIC Studio software contains a Python programming module, which can directly perform custom modules’ development. 

Q2. There is a requirement for the concentricity of rotation when using the gripper, so when the two sides of the gripper are close, does it stop at the middle position each time?

Answer: Yes, there is a symmetry error of <0.1mm, and the repeatability is ±0.02mm.

Q3. Does the gripper product include the front gripper part?

Answer: Not included. Users need to design their own fixtures according to the actual clamped items. In addition, SCIC also provides a few fixture libraries, please contact the sales staff to get them.

Q4. Where is the drive controller of the gripper? Do I need to purchase it separately?

Answer: The drive is built-in, no need to purchase it separately.

Q5. Can the Z-EFG gripper move with one finger?

Answer: No, the single-finger movement gripper is under development. Please contact the sales staff for details.

Q6. What is the clamping force of Z-EFG-8S and Z-EFG-20, and how to adjust?

Answer: The clamping force of Z-EFG-8S is 8-20N, which can be manually adjusted by the potentiometer on the side of the clamping gripper. The clamping force of Z-EFG-12 is 30N, which is not adjustable. The clamping force of Z-EFG-20 is 80N by default. Customers can ask for other force when purchasing, and it can be set to a customized value.

Q7. How to adjust the stroke of Z-EFG-8S and Z-EFG-20?

Answer: The stroke of Z-EFG-8S and Z-EFG-12 is not adjustable. For Z-EFG-20 pulse type gripper, 200 pulses correspond to 20mm stroke, and 1 pulse corresponds to 0.1mm stroke.

Q8. Z-EFG-20 pulse type gripper, 200 pulses correspond to 20mm stroke, what happens if 300 pulses are sent?

Answer: For the standard version of 20-pulse gripper, the extra pulse will not be executed and will not cause any impact.

Q9. Z-EFG-20 pulse-type gripper, if I send 200 pulses, but the gripper grips something when it moves to 100 pulse distance, will it stop after gripping? Will the remaining pulse be useful?

Answer: After the gripper grips the object, it will remain in the current position with a fixed gripping force. After the object is removed by the external force, the gripping finger will continue to move.

Q10. How to judge something is clamped by the electric gripper?

Answer: The I/O series of Z-EFG-8S, Z-EFG-12 and Z-EFG-20 only judge if the gripper stops. For the Z-EFG-20 gripper, the feedback of the pulse quantity shows the current position of the grippers, so the user can judge whether the object is clamped according to the number of pulses’ feedback.

Q11. Is the electric gripper Z-EFG series waterproof?

Answer: It is not waterproof, please consult the sales staff for special needs.

Q12. Can the Z-EFG-8S or Z-EFG-20 be used for the object larger than 20mm?

Answer: Yes, 8S and 20 refer to the effective stroke of the gripper, not the size of the object being clamped. If the maximum to minimum size repeatability of the object is within 8mm, you can use Z-EFG- 8S for clamping. Similarly, Z-EFG-20 can be used for clamping the items whose maximum to minimum size repeatability is within 20mm.

Q13. If it works all the time, will the motor of the electric gripper overheat?

Answer: After the professional test, Z-EFG-8S has been working at an ambient temperature of 30 degrees, and the surface temperature of the gripper will not exceed 50 degrees.

Q14. Does the Z-EFG-100 gripper support IO or pulse control?

Answer: Currently Z-EFG-100 supports 485 communication control only. Users can manually set parameters such as movement speed, position and clamping force. The internal of 2442/4160 series can take trachea or straight wire.
