    Thanks panic mode.

    Basically, I have the same your concerns.

    I think I can handle torque calculations.

    I guessed that this is not the right place to ask this, but I had to try, sorry about that.

    If I can take advantage of your time, I'd like to ask you, as last favor, a link to some explanation about inertia matrix. (the one you sent about torque is quite clear).

    Thanks again.

    This, at least, could help a bit

    The available motors should not be a problem.

    What about the first point?

    They're new in the job, the request is a tool to calculate the maximum torque starting from few parameters and tasks.

    Is there any tool to do that? or some guidelines to develop it. I can develop it, but I need to understand which formula to use.

    Panic Mode, you're almost right :grinning_squinting_face:.

    They're new in the job, the request is a tool to calculate the maximum torque starting from few parameters and tasks.

    With the maximum torque they can choose the cheper available motor to do the job.

    I have a 3d software that they can use to create the parts, the only idea I found is to use my software and let it talk with MatLab/Robotic toolbox, a tool I found on the web that should work, but is completely out of my knowledge.

    No BOM/Programming/Design, but the tool should be able to prepare coffee too :smiling_face:

    Hello everyone,

    I have the following need, please consider that I am a computer scientist.

    One customer ask for a tool to retrieve the motors that they need in order to move a SCARA robot.

    Input values will be: Dimensions, degrees of freedom, center of gravity, desired acceleration,desired speed. and possible configurations.

    Output value: Maximum torque, Inertia matrix (maybe this is an input...?)

    Basically, they create SCARA robot from scratch, so they need to know the cheaper combination of motor they need, starting from a list of given tasks.

    Feel free to ask for details or correct me, again, I'm just a computer scientist with no experience in robots, except few interfaces with FANUC or RobotStudio.

    Thanks for your time.

    Regards,

    Simone.
