What are the differences between myCobot-M5, myCobot-Pi, myCobot-Jetson Nano, and myCobot for Arduino?

A robotic arm is a type of mechanical arm. It is usually programmable and assembles functions of a human arm. Such anarm is typically connected by joints that allow rotation or translational displacement.

Robotic arms are irreplaceable devices capable of performing a specific task or job quickly, efficiently, and with extreme accuracy in the modern production process. The earliest research on robotic arms dates back to the 1940s when US Argonne and Oak Ridge National Laboratories used remote robotic arms to deal with radioactive materials. After seventy year's development, robotic arms become one of the most common mechanical devices used in cutting, assembling, palletizing, spraying, and other occasions, and in medical surgery, aerospace exploration, military reconnaissance, etc.

myCobot-M5introduced by the year 2020 with M5 Stack Atom & Basic ESP32 with dual display screens, supporting the faster visual operation and monitoring work status, so programming MyCobot-M5 is simple and easy for every user. Based on M5 Stack Atom & Basic ESP32 providing a full range of IoT modules from main controllers, communication modules to the sensors and actuators, Mycobot-M5 is suited for users emphasizing high performance, reliability, and scalability. Practical cases range from studio helpers that can deliver tools to kitchen assistants that can cookcakes. On M5 Stack open platform, users can browse and search for open source hardware, API interface and diverse cooperation forms in a more cost-effective way.

myCobot-Piintroduced with Raspberry Pi 4B with 1.5GHz 4 core CPU, running on Debian/Ubuntu platform. Built-in ROS and blockly visual programming enable Mycobot-Pi to operate with relatively high scalability. It is regarded as the most affordable portable processor. As Raspberry Pi aims to promote basic computer science education in schools with low-cost hardware and free software, users can enjoy a friendly educational community with the help of the Raspberry Pi press and Raspberry Pi foundation. With numerous books for computing gaming and the inspirational community in an easy-to-use platform of Raspberry Pi, this version is suitable for users ranging from beginners who want to learn python or set up a lightweight platform, to STEM educators and institutions for further research.

myCobot-Jetson NanoBased on the Jetson Nano AI board and equipped with a camera, myCobot 280 Jetson Nano is capable of quick image processing, robotic algorithm developments, ROS simulation learning, etc. Being a powerful small artificial intelligence computer, it can be started by simply inserting a microSD card with a system image, which simplifies beginners' development. Besides, the Jetson Nano board includes a higher-performance and more powerful GPU (graphics processing unit), which leads to better outcomes in eye-in-hand robot projects compared with my robot Pi making more advanced R&Dpossible. Combined with Nvidia's powerful SDKs such as Deepstream, Vision AI applications and services, it is an ideal version to deepen AI and robotics learning for developers. This boosts the potential of the myCobot-Jetson Nano's secondary development.

l myCobot for ArduinoCompatible with multiple Arduino or Arduino-like boards and extensions. Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. While most other microcontrollers systems are limited to Windows, the Arduino Software (IDE) runs on cross platforms including Windows, Macintosh OSX, and Linux OS. This version focuses on the integrity of robotic arms and pays more attention to improving the simplicity of research and development of users. With a range of Arduino boards (e.g. MKR WiFi 1010, UNO, Mega 2560, etc ) and extensible software to choose from, developers and designers can make their unique myCobot to meet their demands. As myCobot for Arduino provides a more open clear development environment, developers can even design their boards without necessarily relying on PCB'A (Printed Circuit Board Assembly). Furthermore, for teachers looking to bring some innovation into classrooms, Arduino Education is ready to empower educators with necessary hardware and software tools.

Q7: I don’t know how to develop robot arm. Is there a graphical interface for operations?

A7: For non-technical players, myCobot and myArm supports drag teaching function, which allows you to teach it every action and instruction you want. Get rid of the traditional path point storage mode, no programming is required. The saved path can be recorded, and different paths can be saved as long as 60mins at most.

Q8: How about the repeated positioning accuracy?

A8: The repeated positioning accuracy of myArm 300 is ±0.5mm.

The positioning of the two products is not the same. The ER 280 robotic arm is a consumer type and is mostly used in the education field. It is recommended to use 1-2 hours to rest for 15-30 minutes. The repeat positioning accuracy can reach ±0.2mm in a short time.The ER 320 is suitable for commercial work within 12 hours, with a repeat positioning accuracy of ±0.3mm. If used in a short time, the repeat positioning accuracy can also reach ±0.2mm.

Q9: Is there a camera on the robotic arm? And is there a visual recognition sorting function?

A9: The robotic arm does not have a camera. But we have machine vision-related kits now available for vision development.
