can we possible to give power supply for robotic arm through battery .can it withstand the power from battery directly.

Hello friend,
Thanks for you question.
The maximum voltage that the robotic arm can withstand is 12.6V, and the maximum current is 4A. You can use battery.
Any problems, you can contact us by E-mail support@yahboom.com

are there any programming tutorials to run custom python code or deploy own custom vision AI model to change gesture and how the robot behaves based on commands?

Thanks for your question.
Yes, We will provide tutorials in details, you can check this tutorials link: http://www.yahboom.net/study/Dofbot-Jetson_nano
And you will provide professional technical support and after-sales service.

Does it support ROS2, I see new changes in RoS1 and ROS2 library, is the robot arm able to upgrade to ROS2?

Thanks for your question.
I am sorry. Currently this robot does not support ROS2, once we have any updates, I will let you know by email.

is arm can control by pthon programming? i am not sure, have pthon lib ? thanks!

Yes. It can control by pthon programming.
We provide python library and python code.

I think my kids got the gear elements a bit twisted or something on the "pinchy bit". Right now it works _sometimes_ to open and close, but very often will lock up and click. When the power is off I can feel some tension while opening and closing the pincher manually, where that action was nice and smooth when it was new. Is it possible to buy a replacement for just that component, or is there any guidance on repair for this issue? Overall very satisfied with the unit, and this issue is related to severe abuse not to any defect :) Thanks!

Thanks for your support to Yahoom products.

What is the maximum gripper stroke range? Can I increase it?

Thanks for your question.
You can buy following servo part to increase the length of the robotic arm and add one or two more servo (joints). If you add more, due to the torque problem, the lowermost servo may not have enough power to raise the entire robotic arm.

Is it possible to control this unit through PLCs ?

Sorry, this product didn't support PLCs.

I know some of you have already asked this question, but is ROS2 still unsupported? Also, the latest System File on the site was uploaded as of June 14, is this one compatible with ROS2? (File Name is "Dofbot_nano_20240429.zip" as SystemFile http://www.yahboom.net/study/Dofbot-Jetson_nano)

Hello friend,
Sorry. DOFBOT didn't support ROS2 currently.

I formatted the supplied U-disk. PLS tell me How to reinstall System image to U-disk. (Dofbot without Jetson Nano　+ Jetson Nano 4GB Developer kit(B01))

Hello, does this item have a lithium battery? If so, is the test certificate available?

Hello friend,
Thanks for your message, this product didn't have battery.
It is directly powered by connecting to the household socket through a power adapter.

In response already posted, Jetson orin nano board cannot connect with dofbot. Then, Can i connect with Jetson AGX Xavier board instead of Jetson nano board? and this model used serial servo motors, how much power can these serial servo motors produce? We have to carry out an ore-collecting mission (within 1kg). and We have a 12V Li-ion Battery. Can I give power supply with this battery? Thank you.

Hello friend,
Sorry, currently we only have Jetson NANO and Raspberry Pi solutions for this product.
We have not tested other development boards and cannot provide further suggestions.

We have two DOFBOTs now and suffer from performance issue of Jeston nano board. So, can we possible to replace jeston nano with jeston orin agx (or jeston orin nano)? Other product like ROSMASTER (https://category.yahboom.net/collections/j-robotics/products/rosmaster-x3) explictly mentioned supported controller but DOFBOT does not mention it. Please check it and hope to get answer quickly.

Hi friend,
At present, we have no plans to upgrade Jetson orin agx or Jetton orin nano on DOFBOT. So we cannot provide more reference. Perhaps this issue needs to be considered from multiple aspects such as structural installation, operating system, code, and hardware.

Can we connect with Jeston Orin Nano board with DOFBOT instead of Jeston Nano board? I think DOFBOT provides expansion board to connect with Jeston Nano and I just replace Jetson Nano with latest Jeston board. If new board provides 40pin GPIO, isn't it enough? Any other considerstions are required? Thank you,

Hello friend, Thanks for your support out product. At present, we do not have a plan for designing Orin NANO for DOFBOT. Sorry. There may be issues with the structure, hardware, software, and system aspects.

Can we connect with latest Jeston Orin AGX Developer Kit(https://developer.nvidia.com/embedded/learn/jetson-agx-orin-devkit-user-guide/index.html) instead of recommened Jetson Nano?

Hi friend,
Sorry, DOFBOT didn't support Jeston Orin AGX Developer Kit.

What is the export control classification number?

Hello friend,
Sorry for late reply. There was some time difference between us, so I couldn't reply to you in time.
Your means is that the customs code for this product?

1. Is it possible to replace gripper with the other one? If it's possible, are there any requirements for the gripper? 2. Can I give power supply to the robotic arm using openCR?

Hello friend,
1. Replacement of other clips is not supported
2. The power supply demand of the robot arm is 12V5A power supply. You can use a power supply with the same parameters to power it

how can a serial servo be replaced. Where is the software/firmware for the YB-EVV01 board?

Sorry for late reply. We are spending the National Day holiday, so i didn't check and reply you in time.
We can't add some attachments here, so you can contact our technical support by E-mail support@yahboom.com
They will reply you in details. Thanks in advance.

Does a more detailed dimensioned drawing exist? Also, is there a summary of the Python modules available?

Hello friend,
