Hi All, How much do you think the appropriate payload of the new turtlebot3? We tried several tests last week to measure the payload of turtlebot3. https://www.youtube.com/embed/sIrlEY8V09Q Payload Test of TurtleBot3 @ ROBOTIS Office (using Dynamixel XM-430 for Turtlebot3 Premium) Thanks, Pyo

Robot specification cloud sourced? Nice! I assume the question here is the max payload. And I don't have an answer to that, sorry. Just a comment. I'm not a robot builder but a software guy, so apologies that I'm likely overlooking technical difficulties. From you video there seems to be discrepancy in the point the robot returns to for almost all weights. Also AFAI understand correctly TB3 is designed to be customizable structure-wise. Provided, software to compensate the payload weight for wheel control seems to be a required component for this robot. So to me the question may become like "what max payload weight should the software handle?". Hope I'm not mistaken

Good question! The reason of the failure of the robot to rotate in this video was a problem of the plate structure. As we put the weight on the robot, the bottom plate hit the floor and could not make the desired turn when it rotated. So, now, we are making the plate stronger and making it easier to assemble. If I answer your question, the maximum load will depend on the type of hardware you have assembled. For example, the maximum load may vary depending on the torque of the motor used, the method of coupling the plates, and the support used. As you know, the shape of Turtlebot 3 is very diverse. Turtlebot 3 in the video is just one example. Attach a picture of the examples we are currently testing. Please enjoy the following videos and news.
