Recently, I began goofing around in Blender and came up with this
Now, I am a beginner and I wanted to rig him to use in unity, and I've been following several tutorials on how to rig characters in general. But the problem is a lot of the time, I end up getting stretching or some pieces of the robot won't follow the other parts, such as the fingers.
I have succumbed to frustration and have decided to put aside my stubbornness to come here and ask for advice.
