Motor Sizing:

Our model contains three spur gears, which runs four legs of dog through shafts. 1.Mass of Acrylic (Body & Legs): 330 grams

2.Mass of Shaft: 50 grams

3.Mass of Nuts, Screws, Bolts & Washers: 120 grams

4.Mass of DC Motor: 100 grams

5.Total Mass: 600 grams

Radius: 10 mm

F=mg= 5.8 N

T=F*r= 5.8 Nm

Here we require DC geared motor of 30 rpm.

Battery Sizing:

Voltage rating	Current rating
12V	780 mA

Therefore, in our model we will use one adopter.

Adopter: 12V,1A.
