    Hello I need help understanding the simtools axis configuration using this kind of 6dof platform .(planning to build one)
    how can I determine which motor corresponds to which axis in simtools and which movement to assign to each motor correctly ? I’ve read plenty post and manuals about how to do with 2 dof and is clear, but for 6dof like this im confused. Thanks

    You get to assign what each axis does, it really is no different for a 6DOF than a 2DOF, other than the latter is constrained so axis are combined/simulated (like heave) within the now allocated axis range, which SimTools then takes care of in terms of mixing, please see the SimTools manual and quick start guide in the FAQs: https://www.xsimulator.net/community/faq/simtools-v3.401/

    Thanks for the info noorbeast! Another question… what are the calculations to do regarding the distances of motors and pushing rod length? Example : if at the base the motors are at a distance of 1 meter with 10 cm arm, how long the rod should be using a frame like the one of this post?
