Congratulations! The green 6DOF arm successfully settled into my lab

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....

DOFBOT Kit

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.

100 % Recommend. I love it!

- We got our kit on time and well packaged
- The instructions/manual provided were so easy to follow. So assembling took less than an hour.
- GREAT CUSTOMER SUPPORT!!! I can't stress this enough. At some point, I ran into a few roadblocks where I couldn't properly have the robotic arm connect to the WiFi. And the camera stopped working to due to a mistake of mine. For multiple days, the support team has been patiently guiding me through every step until I had everything working again.
- Their documentation is also detailed and provide all you need. The support team is so fast at responding to your inquiries and are so willing to help if you need further assistance.

I am enjoying this kit so far and I am considering buying another one (probably the Jetson one) for future projects.

Thank you YAHBOOM, you are the best!

excellent quality of components.

Products were delivered in a timely.
Kit is well made and clear instructions that are easy to follow, software all compiles, publishes and runs first time. I would recommend downloading the instructions ahead of time and see what involved and required. Website is good and everything available for download including links to both the integrated development environments for the software.
Took about 5 hours fully assemble and test. Great kit, well made and packaged.

I got it on time and they work great.

---Package:
The CE, ROHS certification mark is printed on the DOFBOT box, which looks very safe.
A lot of black sponges are filled inside to avoid damage to parts due to collisions during transportation.
The robotic arm is installed, which saves me a lot of time before I can enjoy it quickly.
---Material:
The mechanical arm is made of green aluminum alloy, which should be able to be used for a long time.
---Battery:
There is no battery in the kit, there is a power adapter and adapter cable, which means you can only use it where there is power.
If you want to use it outdoors, it might be better to choose a robotic arm trolley with batteries.
---Usage:
I spent 2 or two cars to test all the programs on the APP, and most of them can be used normally. Except for advanced color calibration, I can't always debug the appropriate parameters accurately.
I tried 5 times, and finally completed the calibration, which can realize the function of using color interaction.
By the way, regarding color calibration, you may need to keep trying many many times like me.
Technical support cannot only tell you that you need to adjust the scroll bar on the APP. They cannot go to your home or the school to actually help you adjust.
Due to this color recognition calibration problem, I scold the technical support, but they still patiently responded to all my questions.
I am ashamed of my previous behavior. Sorry...

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.
