The specs: - 12 legged walker - Driven by 2 Lego Technic Large angular motors - Powered by Buwizz 3.0 - 1 Technic L motor powers the deployable spinning Lego buzzsaw - 1 Technic S angular motor to power the Lego arrow shooter Sorry Lego purists, but I had to use some non-Lego parts in this design: - 4.7mm aluminum tubes front run the width of the robot providing lightweight articulation of the legs in lieu of plastic axles - Stainless steels axles are used throughout the driveshaft due to the inherent limitations of backlash and breakage caused by the Lego plastic axles - Small nuts are threaded onto the upper leg pivots to maintain the connection as Lego bushes simply cannot retain the axles given the duty cycles.
