Track Recording & Learn by hand

Get rid of the traditional point saving mode, myCobot supports drag trial teaching to record the saved track and can save up to 60mins different Tracks making it easy and fun for beginners to learn robotic arms.

How to control myCobot Pi?

Learn by Hand: Get rid of the traditional point saving mode, myCobot supports drag trial teaching to record the saved track and saves up to 60mins different tracks making it easy and fun for new players to learn.
You can use the digital pins on the robot to make it communicate with other devices.
With Myblockly, our free desktop application uses blocks to create your own robotic programs. Based on Blockly (similar to Scratch), our visual programming interface allows you to quickly and easily create robotic programs without any prior programming knowledge. You can also use RoboFlow, our software for industrial robots.
Advanced Users: develop your own controller (use a computer mouse, a keyboard, a game controller or Leap Motion to control myCobot according to your preferences and needs), use our API (Python、C++、C#、Javascript) to control myCobot directly or remotely or dive directly into the ROS code, which is open-source.

Provide maintenance and repair information (such as video tutorials, Q&A, etc.).

Package Includes:

1x MyCobot 280
1x Power Supply
1x Cable Set
1x User Manual

Frequently Asked Questions (FAQs)

Q1: Does it support secondary development of functions?

A1: Of course. You can use our API (Python、C++、C#、Javascript) to control myCobot directly or remotely or dive directly into the ROS code, which is open-source.

Q2: What can one learn?

A2:

With myCobot M5 , you can learn that

Hardware: Embedded Microcontroller Based on ESP32, Motor and Steering Gear, M5Stack Basic/ Atom;

Software: Arduino, UiFlow, Myblockly, Mind+, RoboFlow, C#, C++, Python, Javascript, ROS，MoveIt, Communication Data, Virtual Machines & Linux (visual system).

With myCobot Pi, you can learn that

Hardware: microprocessor, motor and steering gear;

Software: Myblockly, Mind+, RoboFlow, C#, C++, Python, Javascript, ROS, MoveIt.

Q3: How long it lasts?

A3: It uses adapter power instead of battery power. It can work all the time as long as power supply. But we don't suggest keeping it working for a long time.Just like you use a computer, letting it take a rest at times is better.

Q4: How much weight can it lift / grip?

A4:

myCobot 280: The net weight of myCobot is 850g, the payload is 250g, and the working range is 280mm.

myCobot 320:The net weight of myCobot is 3.5kg, the payload is 1kg, and the working range is 320mm.

myCobot 260:The net weight of myPalletizer is 960g, the payload is 300g, and the working range is 260mm.

myCobot Pro 600:The net weight of myCobot Pro is 8.8kg, the payload is 2kg, and the working range is 600mm.

Q5: What is warranty on this?

A5: Please refer to the warranty policy mentioned below.

Q6: How long will it take to ship after I placed the order? And What kind of logistics?

A6: If the product is in stock, we ship within 24 business hours. In case of pre-order, we may take 3-4 weeks to ship the product.

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

A7: For non-technical players, myCobot 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 myCobot 280 is ±0.5mm, and the repeated positioning accuracy of myCobot 320 is ±0.3mm. The repeat positioning accuracy of the two manipulators is determined based on the length of use.

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.
