Description
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 0.3MP camera. We built an operating system specifically for it based on ROS Melodic, 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 robotic arm works very well, and the functions on the APP are also very comprehensive.
Everything is going smoothly with the current use, and we plan to purchase other robots from Yahboom again.
The package arrived on time today, the packaging is very sturdy and well protected. After unpacking, all the accessories are neatly arranged and the instructions are clear. There is no damage, the product looks high quality, and I can't wait to start using it right away!
The logistics is also very fast, and the overall experience is great.
Even after a long distance of transportation, the item looks intact, great！
I have managed to assemble and run it within few hours with my Raspberry PI5. The image included on your sd card was for RPI4 but I have downloaded the once for RPI5 from your repository and flashed to a new sd card. It works fine. I just need some help with understanding where are your autostart scripts located and how to adjust them to run updated docker image with my modifications?
Thanks for your support.

Although it was an international order, the logistics speed was very fast and the package was delivered intact. I have assembled it and am currently conducting testing with the assistance of technical support.
We received the package from China on the 6th day after placing the order.
The packaging is very complete and looks like a brand new product. I was very angry when I purchased a product I had used from another brand before.
It comes with an instruction manual, which is actually just an assembly manual with a lot of annoying text.
If you want to learn programming and implement some features, go directly to Yahboom's website to read some tutorial materials online or download the PDF files provided by Github.
I will continue testing and provide further feedback if there are any issues.
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.

What is the biggest difference between getting the Raspberry Pi version versus the version without the raspberry pi? What are the limited capabilities if I don't get the Raspberry pi version?
Hello friend,
The Raspberry Pi is equivalent to the brain of the DOFBOT robotic arm. Without the Raspberry Pi, the DOFBOT robotic arm will not be able to start and work properly.
-
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.
