Robotics designers in the US have long gotten their inspiration from 
both science fiction and biology, and engineers are no 
different, most especially those working on walking combat robots.  Dai 
Jinsong and other engineers of the School of Mechanical 
Engineering, Nanjing University of Technology, have published three 
articles in weapons design journals as part of a long term study
 into the design of a legged, autocannon carrying robot.  The extent of 
the study indicates a serious effort. The first article discussed 
modeling gun accuracy and building an eight-legged demonstrator and the 
second articles involved application of computer aided design (CAD) 
software to improve the testing process.  Most importantly, the third 
paper analyzed the systems integration of components like the nine 
channel signal driver module, RS-845 communications module and STM-32 
syncrhonization set, which were required to build a unique unified 
control system for its eight limbs.<br />
<br />
 The "crab walker" design is roughly 6 meters long, and two 
meters wide, including its legs.  It has eight main legs, four on each 
side of the body, and has two rear mounted legs to brace itself for 
stabilization during firing; there is also another stabilization leg 
installed in the front).  The size of the Crab Walker would make it 
capable of being airlifted by heavy helicopters like the Mi-26 and its 
prospective replacement, the Sino-Russian Mi-46.  During transport, the 
Crab Walker's three stabilizing legs would be retracted to allow faster 
movement.<br />

not appear to be interested in putting lasers on robots. <br />

In the present design concept, the Crab Walker's main weapon is a 30mm 
autocannon, which is also found on Chinese ZBD-86, ZDB-03 and ZBL-09 
infantry fighting vehicles.  Presumably the 30mm autocannon could be 
swapped for other remote weapons station, like anti-tank guided missiles
 or a mortar.  Also, there are bulges located in front and behind the 
30mm autocannon, which are likely to house communications and sensor 
equipment. <br />
<br />
The available images of the Crab Walker design suggests that the 
horizontal "knee” joints of its main legs are not fully articulated, in 
contrast to the famous American “Big Dog”
 legged robot, which would limit its speed in extremely difficult 
terrain.  This suggests that the Crab Walker is intended to act as a 
close fire support platform for infantry in difficult urban or 
mountainous terrain, that would be inaccessible to heavier wheeled and 
tracked vehicles.  Given the state of current global robotics, it is 
likely that the Crab Walker would at least initially be controlled by a 
human operator instead of deciding where and at whom to aim its big guns
 on its own.<br />
The Crab Walker is currently a drawing board design, meaning it could be
 superseded by different unmanned vehicles designs, whether legged or 
wheeled. In either case, it shows how the future of land warfare, 
including for Chinese forces, will likely have some kind of robotic 
element.<br />
