FR508 Guanyiwu

After the test of *FR507 Quinque-pedal Mech* and *FR506 Quadru-pedal Mech*, I found robot with compact mech legs strong. And theoretically a 3-legged one would be even better. Comparisons between 3-legged mech and 4-or-5-legged mech are listed below. Advantages of 3-legged: + slightly higer cruising speed + turning faster + free from wobble problem (is this bug or feature? @kk91) + more cpu for blocks -> steeper slope of gun arrangements ([RS82](https://robocraftgarage.shaf.fun/lists/15) for this one)-> better downward clearance + more compact. stiffer in terms of profile area / HP ratio The disadvantages of 3-legged are mostly due to thier incapacity to fit in tracks: + less movement redundancy + less total HP We can see that the advantage of 3-legged ones are more remarkable than their disadvantages. As far as I know, Anguishire and Pikachu_3000 have this kind of robots, which inspired mine. Anguishire's is in *RCG*. I can not find the post about Pikachu's although often see it in game. What bothered me the most when building this was seat protection. I was putting the seat in front of the middle leg. At first I placed the guns regularly. The armor before the seat was far too weak. And the robot spilt into two halves and explode very early in the PVE test. My solution is move forward the gun that is in direct front of the seat, leaving space for armors. The strengthened armor fromes a nose-like bulge. So I just painted it black in simulation of the anti-dazzle coating on planes. The trifroce is pretty simple. There is no leg interconnection because of limited space. Some of the guns are directly attached to the armor. The interlaced 3 * 2 seat mount carried. An interesting detail of this robot is the diagonal-ish side gun mount. One side gun is top mounted while another is side mounted because of the limit of CPU. And there is at least a direction to angle without firepower loss. --- **References** + [Anguishire's Marrin](https://robocraftgarage.shaf.fun/robots/28), rear-mounted e-plates + [FR309 Tripedal Mech](https://robocraftgarage.shaf.fun/robots/69), preceder + [FR506 Shiqüe](https://robocraftgarage.shaf.fun/robots/133), my quadru-pedal mech + [FR507 Xiashuying](https://robocraftgarage.shaf.fun/robots/131), my quinque-pedal mech
