ALPHADOG


ALPHADOG
A soldier’s best friend Get to know the petrol-powered hydraulic pet that can travers e almost any terrain. Very little captures the imagination more than a fully functioning robotic ‘pack horse’ that moves just like the real thing. This stunning machine has four legs that are independently controlled by a central computer, using the data from dozens of sensors. The data is continuously translated into navigation and stability requirements.
The requirements are then translated into leg and hip movements by a powerful hydraulic system. The screaming petrol engine turns a high-pressure pump to push oil to 16 hydraulic servo actuators (four in each leg) through a network of filters, manifolds, accumulators and valves. This moves each leg quickly and precisely. The advanced stabilisation gyro and accelerometers keep the AlphaDog on its feet through mud, sand, snow and even ice. The technology and techniques developed on the AlphaDog have led to a two-legged version that moves just like a human, which opens up all number of possibilities for the future.
