When Google announced its purpose-built, self-driving car program in May, the prototype it used for demos was a very rough, early build. After testing all of the different systems in a variety of prototypes, Google has built its first complete robo-pod that's ready to take to the streets.

For the past several months, Google has been working on a series of builds, with different prototypes used for different systems.

…for example, the typical "car" parts like steering and braking, as well as the "self-driving" parts like the computer and sensors. We've now put all those systems together in this fully functional vehicle – our first complete prototype for fully autonomous driving.

This latest prototype puts all of those bits together into a single package, and if you look at the complete build above and the original below, you can spot the differences, including the new LIDAR unit and real headlights.

Google says it will be running the newest build around its test track over the holidays with "safety drivers" that can use the temporary manual controls if necessary.
