We sure do! We can ship products to most countries around the world.

Please be aware that different countries have unique customs rules and regulations. If your package gets held at customs you will be responsible for communication and any additional costs required to release your item(s).

According to our previous experiences with international shipping, the logistics would contact the receiver first and let you know the documents needed for customs clearance. When there is an issue with the shipping or you need additional documents from us, please feel free to contact us via hello@wristline.com and we will always be ready to help you.

For purchases, shipping will be calculated at checkout.

When your order ships, you will receive a separate email with a tracking number to track your order. Sometimes this email gets sorted into spam or promotions folders, so be sure to look there if it feels like you have been waiting a little too long.

You can also log into your account and click on the order to see the status.

*Please note that sometimes the tracking can take a day or two to be updated by the carrier. If it looks like its not moving, chances are it is on its way! 

We typically ship in 1-5 business days (Mon-Fri). And you will receive your order in 10-15 business days (Mon-Fri). Please know that we are doing our best to get orders out promptly.

To be eligible, items must be undamaged and unmarked, and in their original packaging.  

There have been 0 case in the 2022 full year reported as missing package shipped from WLKATA. So the chance of a lost package is very low. 

If it does, although our shipping carriers work independently to deliver your parcel, we’ll figure this out together!

If it's been marked delivered and it's only been one day - sit tight! Sometimes the carriers scan it before it gets to you. Keep an eye out for the next few hours!

If the tracking hasn’t been updated in an unusually long time or it has never been updated since it was made, chances are it was lost in transit. Please contact us via email (hello@wristline.com) or WhatsApp; and at the same time please file a claim with the carrier. We will work together to find out the status of your order.

If the shipping address was a temporary location, we do not assume responsibility if the recipient is no longer at that address upon delivery within the projected shipping timeline.   

A1: Please check whether the USB is directly connected to the robotic arm. If the update fails in WLKATA Studio software, please refer to the online user manual for alternative method.

A2: Please check whether the USB is directly connected to the multifunctional extender box, and check whether the extender box is normally connected to the robotic arm.

If the update fails in WLKATA Studio software, please refer to the online user manual for alternative method.

A3:  Please check whether the connection of the mechanical gripper and the multifunctional
extender box is correct. The machinal gripper should be connected to the “GRIPPER PWM” port of multifunctional extender box.

A4: The air pump and mechanical gripper cannot be used at the same time as they share the same port of multifunctional extender box, so they can only be controlled separately.

If you want to use them at the same time, please purchase the AI Development Kit which includes a master control board based on Arduino that allows connecting multiple end-effectors, robotic arms, and accessories.

A5: The conveyor belt and the sliding rail can only be used separately when connecting
to multifunctional extender box.

If you want to use them at the same time, please purchase the AI Development Kit which includes a master control board based on Arduino that allows connecting multiple end-effectors, robotic arms, and accessories.

A6: Please check the air pump and multifunctional extender box connection and please make sure the air pipe is connected to the end-effector.

A7: After the calibration of the robotic arm, please make sure to click Finish in the Settings to save the parameters.

A8:  Please refer to the common error in the user manual for more detailed explanation and
troubleshooting. If any further information and assistance are needed, please feel free to reach out to technical support.

A9: Please refer to the common error in the user manual for more detailed explanation and
troubleshooting. Or please update the extender box to the newest firmware version. For update instruction, please refer to the user manual on the official website. If any further information and assistance are needed, please do not hesitate to contact technical support.

A10:  Please refer to the multifunctional extender box user manual on the official website for
details.

A11:  Please refer to the conveyor belt manual on the official website for details.

A12: Please refer to the sliding rail manual on the official website for details.

A13:  The robotic arm and the host computer version may be inconsistent as the robotic arm
version might be too old or WLKATA Studio version might be too new. In this case, the software may fail to identify the robotic arm firmware. Please update the robotic arm firmware to the latest version. For update instruction, please refer to the user manual on the official website.

A14:  Please connect USB to the multifunctional extender box to download the BLOCKLY /GCODE
file. In addition, please make sure SD card is available in the multifunctional extender box.

A15: Please ensure the multifunctional extender box mode is set to BLE 4.0, and then connect the teaching pendant.

A16 Case 1: The robotic arm operation has crashed. Please restart and home to resolve.

Case 2: The robotic arm body may be stuck for some reasons,
resulting in abnormal homing operation. Please check if hard limit is reached, if so, please restart and rehome to resolve. For more common errors’
explanation and troubleshooting, please refer to the user manual.

A17  Case 1: Possible limit switch failure.

Troubleshooting procedure: Power off the robotic arm, keep
the 2nd and 3rd axes away from the limit switch. Then use $H1 to $H6 to home each axis separately. If any further information and assistance are needed, please do not hesitate to contact technical support.

Case 2: Calibration error.

Troubleshooting procedure: Check the parameters with $$
query and check $150 - $156 value. Recalibrate robotic arm if all zero or numbers are not correct. For robotic arm calibration instruction, please refer to the online user manual.

A18 Try to unlock by sending “M50” command, set “$20=0” and “$21=0” to turn off soft and hard limits.

After that, rotate the 6th-axis to correct position and turn on the soft and hard limits by “$20=1” and “$21=1”.

For more common errors’ explanation and troubleshooting, please refer to the user manual.
