How to make the combat robot

So you’ve decided to create a robot, but have heard that it is too difficult. I have for you is very welcome news. To make a competitive fighting robot, requires minimal technical skills to acquire that much easier than you think.

For example, I – a specialist in computers and have never in their lives faced with the need to improvise something with his hands. This continued until my children came up to me and did not say: “Dad, you’re doing us a robot, or we are looking for another father, who we do it.” So me and had to find out what is different from the bush lerki. 

But they came and asked, and I had to learn all this, and after a year or so (after many failed attempts) I have a good ultralight cuneate robot Anorexia (I gave him this name because he went a little) (Anorexia — “anorexia”). This robot can be seen on DVD, released Robot Club & Grill MAYHEM. Then Anorexia hook screw for the ceiling and in the process of repair has become a good truck, which would have been even better if I carefully drove the car.

(By the way, if you click any of the small images, it will be possible to see enlarged version.)

So, do not hesitate to shelve the case, proceed to the case. This year again, the children come to me and said that now they want their own robot, which simply must be at least some weapons. So I had to go back to the bench.

The case is complicated by the fact that I wanted was just to make a robot that can be used many before me have the spare parts (like batteries, speed controllers, etc.) and that for various “navorochek” use simple components: both easier and faster. The time I have been limited because prior to the qualifying competitions for the south-western states remained only a few months.

This sport (and the creation of the combat robot can be safely attributed to the sport) is constantly evolving, and now you can easily get a lot of proven components, through which even the novice will be able to build a good robot. In other words, I have basic skills, but to make a big box to transfer any torque arms I am not able to. Fortunately, neither me nor you do not want to.

In developing the design of the robot, we decided to operate on the principle that the best defense – the attack. All resources are aimed at weapon – blade lawn, which is driven by electric motor Magmotor. I save every gram to make the blade is the most difficult, and in the end, we got a whole block of tool steel weighing 6.9 pounds (3.13 kilograms), length 22 inches (56 centimeters).

Basically, I used standard parts, and if the design turned out to be unsuccessful, many elements could be replaced by more suitable. The decision proved right: the article describes the fourth version of the robot.
 

The first model was a something like the letter “T” made of aluminum with a lot of holes to reduce weight. Casters and wheels of the plane of rotation of the blades were directed at an angle to each other, so the robot can easily rotate, it is not moving their arms. However, when moving back was given rasp, as if kolyut nuts. You can not say that this is the best design, but with a disastrous shortage of opportunity to turn to the protection of the most dangerous enemy of his party seemed to me a great advantage.

Two weeks before the first intervention had to re-design. When moving the robot hub transfer box touches the ground, because of what he lost in maneuverability. Obliquely arranged wheels allow the robot to turn on pyatachke, but when moving back there have been problems.
 

So, I went back to the drawing board, and after a while I get the robot to the displaced axis of rotation, a bit reminiscent of a light 2EZ. At least, the train in welding.

At the competition showed that the robot had to be called “Kamikaze”, because after each attack, he overturns and completely defenseless. After one of the blows he had to ride across the scene. So, again, had to go back to the drawing board.
