Building a Robot is Easy!



Every time we see robots, we are always in awe because of such amazing inventions. We give high praise to the inventors because we know that building robots is not easy. However, we must remember that everything starts with small things. Therefore, even in making a robot, there is definitely a simple way on how to build it. Let us take a look at one of the easy ways on how to build a robot.

In building a beetle robot, the materials needed include the following:

-Mini glue gun
-Diagonal cutter
-Electronic solder
-Soldering iron
-2x - sub mini lever SPDT switches
-1x - meter of electric wire
-1x - wooden pearl, which is needed for the caster
-1x - 2 cm of heat shrink
-1x - battery holder AA
-2x - big paper clips
-2x - small paper clips
-2x - small 1.5 Volts of motors

The first step on how to build a robot is to cut thirteen pieces of 6-cm electric wires and then both ends of each of the 6-cm wires should be stripped at least 1 cm long. Each wire should then be soldered to each component mentioned above aside from the two batteries.

The next step on how to build a robot is to make a connection with the use of the battery holder. The result of this is another connection. Make a connection using the black and red wires while the blue wire creates the new connection.

The battery holder should now be turned upside down, letting the batteries face the ground. The two SPDT switches should then be glued to the battery holder, forming a V shape. The motor should then be glued to each of the switches, allowing the shaft to touch the ground.

The next step on how to build a robot is to make the caster with the use of the big paper clip. Now, create an antenna using the small paper clip. The antennas should be glued to the switches but we must take note that only small amount of glue should be used. The shaft of the motors should be added with a centimeter of heat shrink.

The last step on how to build a robot is to put the batteries inside the holder, place the finished product on the ground and see how it moves!

See, it is not difficult to create a simple robot. As soon as we learn to build small or simple robots, we just have to think big in order to be inspired to create bigger ones.

Robot Drawing – How to Draw a Robot



Robots by their very nature are science fiction and this area appeals to many fans of the genre, and so it is quite right that we go through another drawing article on how to draw a futuristic robot from scratch, it is important to note that this article and the following link are only an idea of inspiration and one possible way to draw a robot as you own imagination will apply to your own robot creations.

Every drawing must have a framework and a robot is no different. However, unlike the human body you can draw a robot based off a human form or just something entirely futuristic with its own structure and shape, but in this tutorial we have the humanoid structure to work from, and so we start off with an oval shape for the head as usual and then all the joints such as the shoulders, the elbows, the wrists, the pelvis, the knees and the ankles are all roughly sketched in as round circles and then the biceps, the forearms, the thighs and the calves are all sketched in a sausage shaped.

The torso of the robot is like one large fat oval egg shape that doesn't have to be stressed over at this point, so long as it loosely connects to all the other robot parts such as the arms, legs and the head.

The above method is ideal for drawing robots, especially as you are marking in all the areas that you want to define, but it necessarily doesn't have to stay that way, not with it being a robot anyway, there is a tendency to try and draw too much detail right at the beginning, but this is advised against as the more you learn to draw from the start by planning your sketches then the better your drawings will be every time you draw.

The next step is to slowly change them sausages and circles into actual robot body parts that look like they would move and be essential working parts, to do this you can just sketch over the circle and cylinder shapes by using them as the original framework, let your imagination take over at this point, because you want to envision a futuristic robot with heavy metal plated armour, or something that resembles metal casing, we could also sketch in a gun on one of the robot arms just to see if it works.

Details are important in this third stage of robotic drawing development, and we can start to add more design features to our robot design, wires and other buttons can be added and a blank robot face makes the robot appear with no emotions. Cleaning the drawing up is a good idea too and inking over the pencil lines makes your drawing stand out.

Drawing robots is something that can be learnt like any other thing you can possibly learn to draw, so just enjoy using your imagination to create them.

Robotic Fire Fighting UGVs and UAVs – Put Out the Fire and Save the Trees!



Every year, firefighters die fighting fires to save lives, but what if firefighters didn't have to die to save others? What if we had robotic firefighting equipment that used unmanned ground vehicle technologies - what if we used unmanned aerial vehicles or UAVs to put out wildfires to save our trees? We have these technologies now, and it is just a matter of allocating some research and development dollars and making it available.

In a burning building, a robot can go and find people who are trapped or in burning rooms and open up like a pod and the people can get in. The pod would protect him as the building burned around them. If the building collapsed they would be safe inside with oxygen, and all they would have to do is wait until the firefighters in cleanup crew could dig them out later. Each pod would be found quite easily due to a home-tracking device. Robotic tractors could go through the rubble and retrieve the pods.

We already have firefighting aircraft, but what if those aircraft were unmanned aircraft - what difference would it make? It would be safer, and we would not have to risk pilots lives to do the flying and the robots would not get tired. Plus, the unmanned aerial vehicles would be less expensive to manufacture or because they would not have all the pilot controls and it would save a third of the cost.

Additionally, the robotic equipment would perform better, because they didn't have the weight of the pilots, that means they could take extra firefighting retardant or Phoschek. Let's use robotic firefighting UGVs and UAVs to put out fires and to save our trees.
