Hardware Issues

Q1: What is the maximum angle of joint 1 and joint 6 of myCobot 320 PI?

A1:

Q2: How are the six servos controlled?

A2: The servo is controlled by the atom on the top.

Q3: What is the role of atom in the robotic arm?

A3: It controls the robot through algorithms such as forward kinematics, inverse kinematics, and coordinate switching. Atom is not open source yet.

Communication issues

Q1: Why is there no display on the screen when the robot is connected with an HDMI cable? Do I need to download the port driver?

A1: Check if the connection is correct and the power is turned on. Try to use another interface and insert the interface stably. No need to download the port driver.

Q2: What versions of communication interfaces do different robotic arms support?

A2: The microprocessor-based robotic arm supports socket communication TCP; the microcontroller-based robotic arm can communicate via USB to serial port.

Q3: What is the communication frequency of the robotic arm?

A3: 10-20Hz.

Question about parameters

Q1: What is the speed unit of the robot arm?

A2: 180°/s.

Hardware Problem Solutions

1. How to deal with the vibration of the robotic arm?

   Step 1: Burn the latest version of ATOM through myStudio.

   Step 2: Upgrade pymycobot. Press Win+R and enter cmd to enter the terminal. Enter pip install pymycobot --upgrade --user and press Enter.

   Step 3: Visit GitHub and download pid_read_write.py. Reset the parameters of the steering engine according to the prompts. Then run the system again.

   Note that the parameters are set according to the data given in the figure below.

About the end gripper

Q1: Can the adaptive gripper not be fully closed?

A1: There is a certain gap between the jaws, and they are not completely closed. You can adjust it by increasing the thickness of the gasket between them.

Q2: What is the communication of the adaptive gripper?

A2: It is ttl communication.

Q3: What communication does the mycobot320 terminal provide?

A3: The mycobot320 terminal provides a 485 communication interface.

Q4: How to fix the USB camera on the end of the robot arm?

A4: Flange fixing is required and can be purchased independently.

Other issues

Q1: Why does the motor power shut off during use?

A1: Because the motor temperature is too high to use. Please wait a few minutes before using it again.

Q2: Does the robotic arm support Android-based development?

A2: We do not support Android development. If you want to develop it yourself, we can provide you with the port protocol.
