I have been drawing a robot with blender and i can not make it move : http://www.doublecopter.ch/blender/robot1-4-7-4-3-3-1.blend please help me finish my robot please i don't know how rigging works and colouring and i want to learn!!!

I got Problems at the tail of the Backbone, I can not connect the leg with the Backbone, it's always disconnected, merge bones command doesn't work, what am I doing wrong??

  • $\begingroup$ I made a second robot that can fly: doublecopter.ch/blender/robotflying3-3-3-5.blend can you rig it and send it to me by email? [email protected] $\endgroup$ Commented Sep 2, 2016 at 8:38
  • $\begingroup$ no offence! But i highly recommend you first learn modeling properly. Your models look cool, but there is a lot to improve. After you have mastered this topic. you can go on to rigging your models. 3D is a very complex topic. if you want too much in too less time, you will get frustrated and loose fun. I can recommend you this tutorial series, it will give you a basic understanding about blender and is a good foundation for a beginner. youtube.com/… $\endgroup$ Commented Sep 2, 2016 at 9:52

1 Answer 1


A quick "tutorial" to give you a way to do it.

First, join all the robot parts. As you used some mirrors but all parts are not symmetrical you may need to correct some geometry (but I let it as is here).

To join all the part, select them all (border select B is good here), then choose a central part to be the main object and Shift select it so that it become the active (but keeping the others selected).

Now hit Ctrl+J to join them all in one mesh.

As I said previously, all is not symmetrical here so you need to rework a bit in order to have a correct mirror symmetry (not visible in object mode but will have some consequences on the rig).

enter image description here

Now place yourself in front view, in face of your robot.

Add an armature (A then armature and single bone). Check "X ray" in the display section so that it will be visible even behind the robot.

Enter edit mode Tab on the armature, move it vertically along Z G+Z, then move the bone's head along Z too in order to make the main central bone for the body.

Extrude it by selecting the bone head then E to extrude and move to place the shoulder. Extrude again for the arms parts.

Then go to the size view Numpad3 and adjust the positions of the bones extremities.

(you can go ahead with the finger with the same technics but I will not do it here)

enter image description here

Rename the bones. This is much easy after that.

In particular for the symmetrical parts, you can suffix (for instance) them with the side they correspond to.

That allows Blender to understand what is what so that you can generate the opposite side automatically using the 'symmetrize' command.

As your robot is more "articulated parts" than "organic linked parts", I think it is better here to parent the robot to the armature this way :

Select the robot and Shift select the armature (in this order) and Ctrl+P to parent. Then choose "with empty groups".

That will create vertex groups in the robot. These groups have the names of the bones.

Now assign each vertices parts of the robot to its corresponding group name.

To do that : select the vertices, click on the group then click "assign".

enter image description here

Here is the result below. For convenience you can activate the "auto IK" (automatic inverse kinematics).

As you can see, this is not symmetrical : this is due to the mesh which needs a bit clean up to be symmetrical itself.

You can also "skip" the shoulder here, as it may be unneeded (this is your choice). To do that, don't create it and extrude the upper arm directly but make it not connected :

  • $\begingroup$ how do I Need to reword a bit? I don't understand (not visible in object mode but will have some consequences on the rig). $\endgroup$ Commented Sep 2, 2016 at 8:47
  • $\begingroup$ @MartinRast, the blend is now at the end of the answer $\endgroup$

  • $\begingroup$ how can I add a bone to the tail of the Backbone, when i extrude the bones of the leg are always not connected to the Backbone... the merge bones function doesn't work, what's the Problem???? $\endgroup$ Commented Sep 5, 2016 at 19:34
