Hence remember to do a rough torque calculation on your design before you get started building it. Things require power to move and the larger and heavier your robot is the greater its power requirements are.
Two of the major things that you might want to keep in mind while designing/building your robot are the size and the weight of the robot. For a start, we can just use simple parts that we find around the house. Recently, there has been a huge boom in the rapid desktop prototyping industry that led to the creation of digital mechanical tools like desktop 3D printers, laser cutters, and CNCs that you can use to build professional looking parts, but those come later. There are a lot of easy to use tutorials available as well. You can try using Sketchup Make which is the perfect 3D modeling software for noobs. There are a number of free and/or open-source software programs available for this purpose. For starters, you can try to 3D model parts for robots. The mechanics behind robots can range from extremely simple jugaad to uber complicated mathematics and formulae involving forward and inverse kinematics as well as other aspects.
So, now that we have the basic mechanical tools and equipment sorted out, let's try to understand what the mechanical domain is all about.
