>>590791I also wish to know
CAD as in solid-based modelling and not surface / parametric splines etc instead of meshes?Do you mean real robots that need to function or fictional + purely aesthetic robots like the Fallout 4 synth in your pic?Would think that'd be like any, but the last time I used a CAD program with any understanding of what was happening was Autodesk Inventor years ago on my dad's WinXP box, it was real easy for middle schooler? elementary schooler? me to make some shapes and boolean and chamfer so my opinion might not be all that meaningful in 2017, just wanna be sure we got your goals outlined with regard to CAD for Robotics.I imagine a lot of it is going to come down to workflow, like can you copy / paste from a pool of assets you made or collected for things like hydraulics / clamps / joints / etc.
>>590800pic is semi-related, its not just for the aesthetics.I want to make a reallife "blueprint" so I can make a robot similar to those from Boston Electronics or what they're called. Also implying that most parts will be 3D printed, at least the outer shell.For the blueprint in specific I am talking that parts do not just intersect but are wired together somehow, probably mostly with screws, or just shapes that go into each other. Also servo placement etc.Maybe so that you can put it in a simulation program more easily , so it speaks the common export languag like obj or Idk what they are.
>>590791While we're at this topic, does anyone know a good free cad/3d database for industry parts and machinery?
After 5 minutes of some research OP found this:http://www.digitaleng.news/de/robotics-software-tools/It mentions that multiple programs are used to design the robot, but the core part is 3D Cad from Solidworks I assume
>>591120... but its not free and I dont think its designed for robotics
Fusion 360, its free for those that arent making over 100k a year.
>>591126What's Fusion 360 like anyway? How would it be described to someone who only ever used vertex-based modelling?Would it be helpful to someone already learning how to make mechanical things with vertex-based modelling or is it just too different to pick up within a month?
>>591126thanks for the tip. Will check it out now-
>>591144It's a parametric modeler. That's all it is.Have you ever made anything using Bezier curves in Adobe Illustrator?Imagine doing that in 3D.Parametric modelers are slightly more anal retentive in the sense that you can add constraints to the lines that make up your shape.In example, Line A must be parallel to Line B. Line B is N mm long, Line C is 45 degrees away from Line B with respect to point BC.That sort of thing.
>>591156Hm. Not sure I'd really benefit from that at this point when I already have nurbs and bsurfaces, but it does sound neat.
Thing OP made in Cad by firstly ripping from the game files and partly retopo-ing (Fusion 360)
>>591161That's pretty suboptimal senpai.
>>591167ikr . need to use this as a template or something
>>590791Design Spark Mechanical. Similar to SolidWorks and completely free. Probably as good as it gets for precision modeling
>>591305tried that out. Seems like it is limited and even harder than fusion 360fusion 360 is shit starting with it being cloud only.
I guess the free CAD software available is very limited after all , and only if you use paid and professional software you can make a good project.
>>590831You can build a robot with any CAD program via assemblies - the hard part is integrating it into a simulator/kinematic solver. These use models based around joint chains/rotations and rough masses. Robot simulations via ROS/Gazebo/VRep use really basic geometric shapes because it reduces computation time for path planning and collision detection. The formats are based on XML (urdf, sdf,etc) and include more meta shit like mass, cog, joint limits along with what you would consider a mesh/STL. Look into tutorials for VRep or Gazebo if you want to dive deeper.
>>591348You can import and export from a disk
Have you tried Onshape? It's web-based and there is a free version of it.
>try to dl fusion from autodesk's site>HURR U CAN'T DOWNLOAD THIS! YOU HAVE A LINUX!>Virtual Machines don't exist!!!Shoe on heqad retarded, made me recall why Autodesk is so horrible - they assume their consumers have the IQ of a fungal spore.
>>592325>won't even let you download it if reads you're not on WindowsThis is pants on head retarded
>>592325Why would you not download it within the VM instead of on the host? Anyways, Solidworks now checks that your running in a VM and stops installation - even with all the QEMU flags that normally get around such checks. That's how I ended up on Fusion 360 with their dumb lack of scrollwheel to zoom+orbit like in Solidworks.
