Hi, Percé.

There are many ways to model the humanoid in SolidWorks.

1. Look models about humanoid robot in 3D, there are a lot of full picture and 3d models. (But don't try to copy, because they have other dimensions and other brand of servomotor and so on .....). You can download and put it like a guide.
2. Keep in consideration, it's very important the dimensions of the servomotors because they are the joints of the humanoid that move the robot. Then draw in a paper some sketchs of the legs, body and arms. The drawings includes the model in 2d and 3d, they guide you to have a concrete concept for your model.
3. To put the sketchs to Solidworks. First, try to model the servomotor with the propers dimensions. Second, make the model of the links, considering the dimensions of the servomotor (joints). At the beginning is hard but then, everything is like a game.
4. For example, if you finish a leg or a arm ... try to improve the design and check is there are not intersections of the solids.. after that, you can add the screws and nuts...
5. Complete it like a game, you can model by parts and assemblies to joints all the parts.

Thank you very much for your intervention.

Merci beaucoup pour votre intervention



Une autre question dans ce que vous avez dit : Comment choisir les dimensions appropriées pour les servomoteurs dans la conception d'un humanoïde ?

Here some popular models of servomotor

Servomotor sg90 (for small prototypes)

Servomotor mg996r (this is suitable for the humanoind)

• chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.handsontec.com/dataspecs/motor_fan/MG996R.pdf (datasheet)

When you select the proper servomotor look at the manufacterer because some dimensions can change (less or more 2 mm)
