Articulated Civis is 18.5m long and carries 110-120 passengers. Below, wheel-mounted electric motors replace drive shafts, saving weight and permitting a low, flat floor.
Blending the flexibility of a bus with the benefits of a tram, the Renault Matra "Civis" eliminates expensive infrastructure. Its Euro 3 diesel engine drives an electric generator, which powers motors mounted in the small-diameter wheels.
Electro-optics guide the vehicle. A camera placed behind the windscreen tracks a painted double line on the road surface. Image processing and direction recognition software generate signals to hydraulic servos on the steering yoke. Civis can follow the lines with a tolerance of a few centimeters. The driver controls braking and acceleration, and can steer the vehicle away from the white lines if required by traffic conditions.
Civis is undergoing evaluation in France. The Regional Transportation Commission of Southern Nevada plans to acquire ten vehicles for a Bus Rapid Transit project in Las Vegas.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
