[MOC] Full RC Compact Excavator
Anto posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This MOC was built after 2 other attempts, 2 years ago and these didn't work. (I can explain a little the reasons if someone is interested) The design was difficult to do because of the round shapes. But I think the result is so good. You tell me ! The functions are : Left track Right track Blade Rotation of the turret 1st section of the arm 2nd section of the arm Moving the bucket Rotation of the arm (right/left) Opening/closing the clamp (pneumatic) All the functions are powered by M motors, except the rotation of the turret. But there are 9 functions, and it is possible to control just 8 functions with the IR system. How it's possible ? It's quite simple ! A gearbox allows to choose between "rotation of the arm" or "opening/closing the clamp". The chassis is very compact. It has 4 motors and 1 IR ! The mechanism of the rotation of the turret is not visible (the turret is too compact ! ^^) The rotation is quite fast (not too slow). Here you can see the motor actioning the 1st section of the arm. The motors of the 2nd section of the arm and the bucket are placed inside the arm. The last motor is placed in the middle of the chassis. It actuates the gearbox and you can choose the function to activate. With the clamp, there are a bucket and forks.
