Pan Dong presents.
New mini truck, they are based on Unimog trucks. 4 wheel steering, this function is the focus of the building. Short wheelbase, portal axles, lightweight body. Two chassis models, like a RC car, one has server motor for steering, the other linear actuator and M motor . But , Both have the problem of turning to the imaginary position. L motor x2 for drive.
I hope you'll like it.thankyou for watching.

這次拼裝的重點,在相對較短的軸距,實現四輪轉向,然後輕量化車身結構,模擬RC車的懸架扭動姿態。有兩種底盤模式,一個採用伺服馬達轉向,另一個是小推桿加M馬達。兩個L馬達驅動,RC輪胎。四輪轉向真是靈活很多,攀爬時候的優勢明顯,不過因為前後各採用兩組萬向節傳動,導致有明顯的虛位問題。伺服馬達轉向,效率直接,但是轉向有類似軸效應現象,車頭會左右擺動。小推桿加M馬達的組合,姿態很棒,不過向上攀爬時後橋壓力大,還是建議採用不轉向的後橋,會更加結實可靠。
