The rear mounted stabilizing legs, as well as the forward-middle leg mount, are deployed to brace the robot against the 30mm autocannon's (of the same type found on the M2 Bradley IFV) recoil.

Robotics designers in the US have long gotten their inspiration from both science fiction and biology, and Chinese engineers are no different, most especially those working on walking combat robots. Dai Jinsong and other Chinese engineers of the School of Mechanical Engineering, Nanjing University of Technology, have published three articles in Chinese 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.
