Out-of-the-box cobot 280 Pi does not move bot when I command send_angles

[michelle-aa-robotics-photonics]

Describe the bug Got a new cobot 280 Pi, set it up and hooked it up to my monitor. The arm seems to be able to read angles through get_angles() but it doesn't send_angles() successfully. As in, it thinks it has but the robot doesn't move. And if you get_angles() after you send_angles() , then it thinks it's updated the angles and returns the new coordinates. But it's wrong because the robot has not moved. If you release the servos and drive the motor around again, it seems to reset itself.

To Reproduce Steps to reproduce the behavior:

1. Move joint angles to [79.45, -50.44, -92.02, -33.13, 69.54, -41.92]
2. Send send_angles([76.2, -43.41, -114.96, -21.26, 68.22, -42.27])
3. See error that bot does not move
4. Send get_angles()
5. See error that bot has updated the joint angles it returns even though it has not moved.

Expected behavior If I send send_angles([76.2, -43.41, -114.96, -21.26, 68.22, -42.27]), I expect the bot to move to those coordinates.

You can use the send_angle interface to verify that each joint can move normally. If you want to control the coordinates, please use the send_coords interface.

Hi! I did use the send_angle interface and it also didn't move the joints.

I misspoke early when I said "coordinates". All I've been checking are the joints.

Please use myStudio to update the atom firmware and try again. Burning tutorial:https://docs.elephantrobotics.com/docs/mycobot-pi-en/4-BasicApplication/4.1-myStudio/4.1.1-myStudio_download_driverinstalled.html

I'm a bit confused -- this page does not seem to have any tutorial on updating Atom firmware, it is about building myStudio?

If you are referring to https://docs.elephantrobotics.com/docs/mycobot-pi-en/4-BasicApplication/4.1-myStudio/4.1.2-myStudio_flash_firmwares.html, these instructions all seem to refer to plugging directly into a computer, which I don't believe the Cobot 280 Pi can do.

You need a USB to type-c cable that supports communication. Connect the type-c end to the atom port at the end of the robot arm. The USB end can be connected to your computer or 280 Pi, and then start myStudio to burn the firmware.
