I get the impression that the designers were young, and have no idea of how a real industrial robot arm works. As a result they built a plastic toy that uses none of the engineering principles that make an industrial robot strong, accurate, repeatable, and useful. A properly engineered metal robot arm that size, with (say) +/- 0.1mm repeatability would be a really useful product, for which £5K to £10K would be a reasonable price range.

Robotics teacher here 👋 I have both this MyCobot Pi and MyCobot Core + accessories (paid myself) and actually suggested to Elephant Robotics to send it to you. Good that they did. ‼️ But note that the code running on the M5Stack ATOM (in the head) is NOT OPEN SOURCE, this wonky python module is the only way to send commands. MyCobot is supposed to be for robot education but it is not possible to run ROS2, Moevit or anything else you would want to use for robots education. Since you can’t write your own interface for the Atom interface, you can also not teach robotics protocols for which there needs to be a proper OPC QA / MQTT interface. had my fair share of trouble with elephant robotics
@dinoscheidt3 жыл бұрын
Had my fair share of trouble with elephant robotics - the raspberry PI comes completely in Chinese incl. the test program, most programs not working - the documentation is incomplete / out of date - claiming everywhere its an open source robot arm for makers and educators but they aren’t. I wanted to fix the atom interface and therefore the code and they replied for “company secrets reasons” lol they wont do that. They likely don’t want to see how some juniors jammed some code together. Which explains why you have trouble with the python code. - The first robot they send me was 3d printed, still charged full price. - This company loves false advertisement. From load, to speed, to repeatability to components used and marketing with open source while its absolutely not. So buyers beware. If you want to see more about the issues, go into the official mycobot facebook group and scroll through. It’s a company that sells and forgets hardware without proper software skills… 💸
