step 6 Step 6

With the joints made and in position we can attached the separate joints to the necessary vertices. Close the build joints menu and open the Hierarchy Joints floating menu. Select the elbow joint in the hierarchy window. In the rear window lasso the top three rows of vertices (see opposite). Go back to the hierarchy menu and press attach. This will assign the selected vertices to the elbow joint. You can now deselect these vertices by pressing deselect.
step 7 Step 7

Do the same for the hand joint but this time select the bottom two rows of vertices (see image).

Save your newly make arm and go into animator.
step 8 Step 8

Set animation length to 30 frames and load the newly created object as a robot.
step 9 Step 9

With the robot loaded insert a key frame in the robots costume time line at frame 15. Make sure the keyframer window is open so that you can see the time line ( press 'k' to open keyframer). In the camera view press on the Go To Frame button and enter 15. This is the newly created key frame for your arm which is required before you can modify the mesh with your skeleton.

Remember a costume keyframe has to be made and the Go To Frame has to be on that frame before you can use the skeleton.
step 10 Step 10

Select the robot actor by pressing 'a' and clicking on robot1. Press 'v' this will display the robot view. In the robot hierarchy window select the hand joint and rotate it about the y axis in any view port this will create a key frame pose for your object.

To create the effect of the object bending insert a key frame at 2 without repositioning any of the joints and follow steps 9-10.
