Note: I did not follow the size listed, just for this tutorial purpose.

Step 1:

Let's start out by creating a new file. I used a 500×400 pixels canvas set at 72dpi, and I filled my background with #004E80 color shade. Now make a new layer set and name it 'Robot Head'. Then in a new layer draw an ellipse with #87FFFF color shade and 67 x 44 px dimensions

Step 2:

Under Layer Style(Layer > Layer Style) add a Gradient Overlay blending option to your ellipse layer.

Step 3:

In a new layer draw a large light blue ellipse with #6BC6FF color shade and 116 x 118 px dimensions, position it as shown below.

Step 4:

Under Layer Style(Layer > Layer Style) add an Shadow, Inner Glow and Gradient Overlay blending options to your large light blue ellipse layer.

Inner Shadow

Inner Glow

Gradient Overlay

Step 5:

In a new layer draw a large black ellipse with the same size as the light blue ellipse.

Step 6:

Under Layer Style(Layer > Layer Style) add an Shadow and Satin blending options to your large black ellipse layer. Then set the layer's blending mode to Lighten.

Inner Shadow

Satin

Step 7:

In a new layer draw a white circle with 36 x 36 px dimensions, this will be part of the eye. Then under Layer Style(Layer > Layer Style) add a Drop Shadow, Gradient Overlay and Stroke blending options.

Drop Shadow

Gradient Overlay

Stroke

Step 8:

In a new layer draw a small black circle then draw a white circle inside.

Step 9:

Now add the right eye by duplicating the original designs.

Step 10:

In a new layer draw a blue ellipse with #004E80 color shade and 28 x 13 px dimensions on the head.

Step 11:

Under Layer Style(Layer > Layer Style) add a Drop Shadow, Inner Shadow and Gradient Overlay blending options to the blue ellipse layer.

Step 12:

In a new layer draw a small white ellipse inside the blue ellipse design.

Step 13:

Now draw 4-6 small black rounded rectangles in seperate layers as shown below. Then set the layer's opacity level of the bottom rounded rectangles to 62% and 45%

Wow your finish. I hope you like the result.
