Using the Treads from 2 POC Hisstanks I built the legs using polystyrene and 4 Cybertron Metroplex arms
the core body itself was built up using foam polystyrene and cut fodder from multiple things
the Turret was some cheap Tank toy with a modified cannon from a old Megatron tank
I Installed LEDS in the core body
Legs do move side to side and up and down and treads still function
I used anything that looked mechanical including household items for this build
