Waiting for 7 days, I received my package. The kit is great!

I am a retired engineer and I really like the special structure design. When I saw it in a Facebook post for the first time, I decided to buy it. I spent an hour to complete the assembly and it is now standing in In my cupboard.
I plan to buy more building blocks to make this robotic arm longer.

Its appearance prompted me to take it to my home, Lol

This is Toby. I am a LEGO EV3 enthusiast.

This is my largest programmable building block robotic arm that I have seen so far. I have to say that its designer is really great!!! The seller provided detailed assembly steps. It took me an entire hour to complete the assembly. I encountered some problems during the assembly process and consulted the technical support. Yahboom quickly replied to me via email (Good service)

But I think Yahboom needs to prepare an installation video for users who are not good at Lego to assemble. (I gave a 4 star review)

The APP remote control function is very stable, and i can control the robotic arm to move some items. I plan to buy some Yahboom building block motors and add them to the bottom of the robotic arm to make a movable robotic arm and turn it into a real porter. I can't wait to start acting......

Works well

The building blocks are complete, and we quickly assembled the robotic arm according to the assembly steps provided on the website. And use the APP to remotely control it, everything is OK.

I have to remind: Before using the APP, you need to download the Bluetooth program to the Micro:bit motherboard, otherwise your Bluetooth will never be able to connect.

Kit is Good Quality, Good Value, and Engaging for Mechanically Minded Children

This kit is Good Quality, Good Value, and Engaging for Mechanically Minded Children. We have bought a number of these sets. Children ages 8-11 may need substantial adult help..Ages 12-16 would be more independent with these activities. There are many very small pieces, hard to maneuver with small fingers, and instructions for assembly are not the easiest.

Reasonable product

Thank you for your quick delivery.
The product was as expected. There was something unclear in the assembly instructions, but it took about 2 hours to assemble.
The length of my Super: bit is longer than that of the instruction sheet, so the mounting position had to be changed.
I think it is necessary to improve the method of fixing the gears of the No. 2 and No. 3 motors.
Low-priced robot arms that use servomotors tend to be unstable, but this is stable. Instead, functions such as positioning require the addition of sensors.

  • Can I order arm without Bbc microbit?

    Thanks for your question.
    Yes, you can choose the version 【Arm building block pack+super:bit】, which means didn't include BBC micro:bit board.
