automobile car
The automobile car that Leonardo drew in his notebook is one of the first ever self propelled cars. It is powered by springs. The car was sketched around 1478-80. It is used to transport gear and injured people more easily. The first time a self propelled car was produced was in 1886 which is four hundred years later than Leonardo drew the design. To make it move you have to pull back the car to spin the gear and coils. This would pull the spring back. When you let go the spring is released and the car is pushed forwards. You can program the coil and gears to make the car go in a certain direction. You can not steer it after you release it. The car will go in one direction. When the car re-invented it went 33 meters (36 feet). Here is a video of the re-invention http://www.leonardo-da-vinci-biography.com/leonardo-da-vinci-videos.html#AUTOMOBILE CAR
