abstract  

the objective of this project is to build a robotic dog that performs tricks that are  

determined by the number of times it is petted. the robotic dog would be a perfect toy  

and friend for a child, especially an only child. it would not require training, since the  

tricks would already be programmed into the robot. although the idea of the robot seems  

simple, the actual construction of this robot is extremely difficult and takes up a lot of  

time. three different models of the body structure were constructed until a fully  

functioning robot was finally discovered.  

background/purpose  

about 10,000 to 15,000 years ago, human beings had developed signs of  

relationships with wolves, which are believed to be the ancestors of the modern  

housedog. the wolves were social animals that traveled in packs that they were willing  

to defend with their lives. social ranks existed in these wolf packs, in which all the  

wolves would submit to one leader. this submission made it easy for humans to raise  

wolves for beneficial reasons because the wolves allowed the recognition of humans as

their leaders. as a result, humans lived in harmony with the human-raised wolf  

companions, utilizing the wolves for hunting, rounding up their flocks, and protecting  

them when intruders were a threat. after a long period of time, the wolves gradually  

evolved into the typical household dogs of today.  

a household dog would be a perfect companion for an only child of modern  

times, especially since less people want to have children and since some only want to  

have one child. an only child with no siblings would sometimes feel lonely or bored and  

would then resort to begging their parents for dogs. the dog could potentially be their  

link to attracting some new friends and some extra attention, especially if the dog could  

perform some tricks to entertain other people. unfortunately, sometimes parents discover  

that either they or their children are allergic to the dogs. in addition, some parents dislike  

all pets and complain that they are too much of a hassle. these conflicts may be solved

by a lego mindstorm robot that performs tricks like a pet dog.  

first of all, the robot has no fur that may trigger allergic reactions and provides  

entertainment for children. it may still help children attract attention and give children  

satisfaction when the robot is petted. this robot may perform certain tricks of the pet  

dog, and the performed trick would be determined by the number of pats it receives. this  

robot needs no training and no food, yet it still provides entertainment for a child, and  

may act as a companion for a child that occasionally feels bored or lonely.

We had such a fright last summer when we arrived at our holiday destination. we had imagined a country cottage in a picturesque village, where we would be able to spend a quite fortnight alone. however, when we arrived at the address  which the travel agent had given us  we could not believe our eyes. the house was opened by a thin old lady, who  was wearing a dirty old dress. she showed us into the lining room,  which was full of old and dusty furniture and had no tv ,  and than left us without saying anything.  as it was late we went up we went up to the bedroom,  which was so hot we couldn’t bear it . we tried to open the windows, but they were tightly shut, so we got into the bed, and tried to get to sleep. after a short time we heart a noise and we looked up and saw a young man trying desperately to open the window just as we had done. when he saw us, he disappeared through the door,  which we had shut before going out . our immediate reaction was to jump out of the bed, grab our things and spend the night in the car. the next day we discovered that the man  we had seen the night before   had committed suicide by jumping out of the window in our bedroom forty years before. every year since than, on the anniversary of his death, he had been seen in the room trying to open this window. since than, however, his wife, the woman  who had opened the door for us , had kept the window locked, which is why nobody could open it.
