Description
Another version
Jetson NANO DOFBOT AI Vision Robotic Arm
This Raspberry Pi robotic arm is mainly composed of an aluminum alloy bracket, a sturdy chassis, a multi-function expansion board, 6 bus servos and a 300,000 pixel camera. We built an operating system specifically for it based on Ubuntu20.04/ROD noetic, using Open Source CV and Python3 programming to create a series of AI vision functions. It can be controlled by APP, PC software, handle, JupyterLab. We provide detailed tutorials, open source codes and technical support services for Raspberry Pi players and AI beginners.

Customer Reviews
The manufacturing quality of this product is excellent. The parts of the robotic arm are made of durable materials, with fine assembly process and stable structure. I am very satisfied with the stability and durability of the robotic arm, as it can operate stably for a long time without any malfunction or damage.
Most importantly, during the purchasing process, I encountered some questions and communicated with the supplier. They are very professional and friendly, promptly answering my questions and providing good after-sales support. I was deeply impressed by their customer service, which made me feel at ease and satisfied during the purchasing process.
The accuracy and stability of this robotic arm are not very high. If you need to complete high-precision and high stability tasks, you may need to consider other better robotic arm products.
Before each use, I need to debug the clamp, otherwise I will not be able to accurately grip the building blocks in the kit. And when I received it, one of the servo motors couldn't rotate properly. Technical support told us that we needed to rewrite the ID using software, as shown in Figure-1.
But this software only supports the Windows system, and I had to borrow his computer from my friend. With the help of technical support, I was able to get the No. 3 servo back to work.
In short, apart from timely and professional technical support, the experience with this product is not very good.
I recently bought this Raspberry Pi robotic arm kit. I was impressed by its functionality and ease of use. The kit is easy to assemble, and the accompanying software and tutorials make it easy to program and control the motion of the robotic arm.
The construction quality is very good, and the arm can perform various tasks in an accurate and accurate manner. The only disadvantage is that the kit has no battery. If you want to use it outdoors, you need to prepare the battery yourself.
In general, I strongly recommend this Raspberry Pi robot arm kit, which is suitable for anyone who wants to use high-quality and multi-functional robot arms on independent websites. This is a very good investment that will provide hours of fun and productivity.
I bought a Jetbot from Yahboom before, I converted it into a lawn mower, this time I bought a DOFBOT robotic arm again, and I will continue to retrofit it. Wish me all the best.
By the way, I'll probably be constantly bothering tech support, HAHAHA....
I am a seasoned roboticist with extended experience in building robots from commercial kits as well as my creations.
Searching for an inexpensive micro controller for my students, I stumbled on a cute and inexpensive robot called Tinybit by Yahboom, based on the BBC MicroBit.
I then realized that this company offered other, more sophisticated robots based on Jetson nano and Raspberry Pi at a very competitive price.
I tried a few and the last I built is the robptic arm for which I’m writing this review.
This Kit is one of the best I have ever built.
It consist of 6 servos, a Camera, an expansion board, sturdy laser cut body parts, all the necessary cables, connectors and accessories plus a well-designed PCB that connects everything together.
In addition, Yahboom also provides a lot of source code and tutorial materials, as well as technical support, as a user you can enjoy professional services.

QUESTIONS & ANSWERS
-
What kind of controller is used for the Dofbot? Do we have access to low level control parameters? can we implement a low-level velocity controller by ourselves? Also in some of the videos, I saw that there is minor backlash when the motion stops, any suggestion on how to avoid it or compensate for it? Thank you.
Hello friend,
Thanks for your question.
1. DOFBOT can use Raspebrry Pi and Jetson NANO.
2. Yes. You can access to low level control parameters. You can control the speed of the servo.
3. The slight rebound is due to the force on the arm. You can solve this problem by changing the speed of the servo or increasing the force on the base of the robotic arm. -
I would like to know if there is any possibility of increasing the payload capacity of Dofbot by using a different powerful servo? If such a modification is possible, then what others change are needed to be done, to keep the precision of robot motion and control.
Hello friend,
Thanks for your question.
If you can recruit a suitable servo, the load capacity of DOFBOT can be increased.
But you need to consider whether your new servo can be installed on the aluminum alloy structure of the robotic arm, the current size of our servo is: 44.37*23.06"35.12mm -
So I would like to purchase the Dofbot Pi version. However i would like to know if there is a possibility for extension, 1. Do you supply any vehicle on which the Dofbot can be mounted 2. Does Yahboom provides different varieties of grippers? 3. Does Yahboom provides and if Dofbot-Pi supports other sensors like LidaR, ultrasonic, etc. ? Thank you.
DOFBOT We do not currently reserve these features you described.
According to your description, the Transbot car is more suitable for you. You can check it: https://category.yahboom.net/products/transbot-pi -
I have unboxed the unit. And when I try to calibrate the servos in the app.. I only get a green circle around Servo 1. And nothing else turns green.. what could be the issue ?

In case of DOFBOT without Raspberry PI version , do you provide the microSD card with OS and Spftware that can be directly used if Raspberry PI is prepared ? Or should I prepare the microSD card and install the Linux OS and Software for the DOFBOT ? I wish you provide us with ready installed microSD card for the DOFBOT system.
Hi Friend, sorry for late reply. There are some time difference, so i didn't reply you on time.
The SD card that has been written into the OS system and software file is the standard configuration of this robotic arm kit. Regardless of whether you purchase a package containing the Raspberry Pi board, you will get a SD card that has been written into the OS and software file. You can use it directly.
Sorry again for late reply. -
Is there a detailed description of the expansion board? I have only seen the top level image of the board showing a list of 12 or so components.
Thanks for your question.
You can check this link to get Hardware Interface Manual. Link: http://www.yahboom.net/study/Dofbot-Pi -
If I buy the configuration without the Raspberry Pi (I already own one) would it be possible to connect it to the robotic arm? Also where can I find a guide on how to do it
Hello friend,
If you have Raspberry Pi board, you just need choose with Raspberry Pi version. The kit will contain all the accessories you need, except the Raspberry Pi.
Any other question, you can contact me by WhatsAPP or E-mail.
