LDD, LEGO Digital Designer, is a software which is used to layout a robot design. This helps people to know what are the components of their robot and where it'll be located. The software provides a 3D view of the parts like beams, axle, pegs, bricks, brains and more stuff included in robotics. It allows the user to build and attach parts of a robot just like in real life. In LDD, there are three options on where you will design namely: LEGO Digital Designer, LEGO Mindstorms and LEGO Digital Designer extended. In the first option, LEGO Digital Designer, you can see a car made up of LEGO and this represents an output that you may do here. In the second option, you can see a robot made up of different sensors, a ball carrier and other things. It's main thought is creating an automatic robot which could be programmed to respond to its environment and fulfill its own task. There are 3 robots below the image, the Basket bot Tribot, QuickDraw Tribot and Wacker Tribot. You can view and revise the design of the robot once you click one of them. The LEGO Mindstorms has the parts of the NXT, RGS and EV3. In the LEGO Digital Designer extended, you may build a community of robots or the design of the area you'll be working on.
The first time I used LDD, I chose LEGO Mindstorms so that the design would be more detailed. I thought it was something which is very easy and I can finish the output without spending an hour. I told myself that it was just like Minecraft where you'll just attach things together and instantly, you have an output. That expectation was quite high compared to what I did. The frustrating thing was I couldn't understand a single thing about attaching things together that I couldn't make a wheel. I asked my teacher a lot about how can I do it and I kept complaining that I don't get it and muttering the sentence, "Why is this happening to me?". After all my complaints, I was able to build a wheel by the use of a hub and a low-narrow tire and that felt like the happiest moment of my life. Even though it is embarrassing that I took a lot of time for finding the parts, I'm still happy for my success and I even attach the two wheels I made with a peg. I couldn't describe the feeling of enlightenment within my heart even though that wasn't a big part of the robot design. It was difficult to manage the LDD but fortunately, I'm learning bit by bit. The second time turned out to be nice and I was able to build a good or just an average output. I'm serious about finishing my robot design even though I encounter difficulties in using it.
In order to use LDD properly, you need different skills and one of these is analyzation. You must analyze which parts will be right for each other so that they could fit in each other. Another thing is creativity. You must know how your design will be presentable and fit with the theme. You must also have the knowledge about robotics so that you'll know what are the purpose of each parts. A normal citizen would take a hard time in completing a robot design but still, they could be trained so that they could achieve the talent in designing a robot.
