Temporary Delay in the Delivery of Unitree Robots
Like many other suppliers, we are currently experiencing delays in the delivery of Unitree robots. A shipment from our supplier is currently held in customs, which has unfortunately led to later-than-planned deliveries for previously placed orders. We are actively working with our supplier to resolve this issue and expect more clarity soon, but at this time, we cannot provide any guarantees.
Additionally, a new shipment is already on its way, though it will take some time to arrive. Since other suppliers are facing similar challenges, switching to a different provider is unlikely to result in a faster solution. Our top priority remains fulfilling existing orders.
If you have any questions or would like to update your order, please do not hesitate to contact our customer service team. We will keep you informed of any further developments.

Learn to 3D Model & 3D Print with Tinkercad
With this book and the complementary videos, you’ll be 3D printing in no time at all. This course is meant to have you make casings for electronic components but also goes into optimizing your print technique as well as adding a little flair to your 3D creations. The course is perfect for you if you just bought your (first) 3D printer and want to print your own designs as soon as possible while also being able to get more background information.
You’ll get to know the workings of a 3D printer and what software to use to model your object, not forgetting to make it print perfectly. We’ll even use the magic of 3D printing to create things that appear impossible to make (this fast and simple) with any other rapid-prototyping technique.
At the end of this course, it’ll be second nature for you to design an object for 3D printing and fine-tune your print-setting to get the perfect print!
The book includes the following 7 video tutorials:
Introduction
Basic 3D modeling for 3D printing

Create Models for 3D Printing, CNC Milling, Process Communication and Documentation
Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication.
OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class.
OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples.
Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!
Affordable solutions with the ESP8266 and 3D printing
If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller.
As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA).
For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop.
Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring.
You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book.
All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.
The uArm Swift Pro is a high quality robotic arm that can be used in a wide range of applications. The uArm Swift Pro was developed and optimized for use in education, which means that many packages are already available for open source platforms such as ROS. The uArm Swift Pro has a position repeatability of 0.2 mm and is also equipped with a stepper motor and a 12-bit encoder. These are just a few reasons that make the uArm Swift Pro an excellent choice for educational use. Another great feature is the 3D printing kit that converts the uArm Swift Pro into a 3D printer in less than 1 minute.
The uArm supports the following development platforms/systems:
UFACTORY SDK
Arduino
Python
ROS
GRABCAD
OpenMV
