Thanks :) 2 Aventador2004: yes, it's me ) 2 MangaNOID: take a look to the real tunneler :) 2 Aleh: Thanks! I'll film detailed video later.

Thank you for many kind words :) 2 AkiyamaWataru: The structure isn't bended - it's an optical effect because of tracks aren't parallel to the ground surface. 2 kbalage: general idea is to connect electric switch and free hanging weight by one axis. The execution is a bit more tricky though )

The topic is updated with detailed review: Hi! I’m glad to show you my new MOC made for Lego and Volvo contest. The task was “Build construction equipment of the future”. My little pet was designed special for Mars developing. Artificial intelligence allows this machine to perform different operations simultaneously. This monster replaces excavator, loader, tunneler, dozer. It can be used for road construction, tunnel boring, preparation of construction sites and many other tasks. All-around lighting system and cameras form 3D vision of the surrounding scene in a wide electromagnetic spectrum. Because of low solar irradiance on Mars the machine is powered by a compact nuclear reactor. Model features: 100 x 36 x 45 cm, weight - 7.4 kg. The model contains 16 motors. 1. Chassis - All-track drive (4x XL-motor) - Independent steering for crab mode up to 90 degrees and zero turning radius (4x M-motor) - Central pylon has an automatic leveling system. The tilt sensor is the weight on a pendant. If lengthwise tilt occurs the weight turns the motor on (buggy motor, I just have no wires for PF motors). The motor is interfaced with four linear actuators which level the superstructure - Central pylon has two co-axial independent turntables for different equipment 2. Loader - 360 degrees rotation (M-motor) - Boom lifting mechanism (L-motor) - Boom extension with synchronized counterweight movement (mechanical binding, M-motor) - Bucket loading and unloading (M-motor) 3. Tunneler - 360 degrees rotation (M-motor) - Boom tilting mechanism (L-motor) - Drilling head has five types of movement (XL-motor). The central part rotates fast in forward direction, the second part – in opposite direction, the third part – slowly in forward direction, eight additional cutters rotate in perpendicular plane. In addition, the whole drilling head unit moves in a reciprocating manner like a puncher - Because of absence of liquid water on Mars I suggest to use a huge vacuum cleaner to remove dust from drilling (you can see six working propellers near the drilling head) All the functions have remote control except for the leveling system – it operates automatically. Please enjoy the video: Thanks for watching!

Thanks for positive feedback :) 2 MajklSpajkl: I used lithium batteries, they work up to -30 without problems :)

Hi! Today I'd like to show my new model - Lego Technic Arctic Truck BIG Brother. It is scale copy of 60035 Arctic Truck. The Lego Technic model is powered by four buggy-motors with two RC units. The gear ratio is 1:3 from slow output. One M-motor is used for steering (auxiliary output). Dimensions: 42x22x29 cm, weight – 2.9 kg.

HI! The instructions are still incomplete but I've filmed new video :)

Thanks a lot! The video was a big problem - I should buy stabilizer.

Thanks for awesome renders!

Thanks for comments! I'm glad you like it :) 2 AFOLegofan66: I still plan to finish instructions for Skidder but I absolutely have no time now.

Review and instructions: Hi! I’m glad to show my new MOC – it’s Merlo Roto Telehandler in 1:11 scale. Here you can see the real machine: The dimensions: 80 x 25 x 30 cm, total weight – 5,7 kg. The max height is 83 cm. The model contains approximately 5100 parts. The model has eight remote controlled functions (three S-bricks, 14 motors). 1. Four L-motors for AWD with diffs. 2. Two servo-motors with independent control for steering. We can steer normal, with reduced radius or crab. 3. Outriggers deploying – two M-motors. 4. Superstructure rotation – one XL-motor. 5. Boom raising – two M-motors. The boom is rather heavy it can’t lift significant additional weights. 6. Boom extension – one M-motor. 7. The rigs operation – one M-motor. I’ve created classic fork and crane. 8. Cab lift for visibility improvement. In addition to motorized functions the model has suspension with solid axles (eight hard shock absorbers), detailed cab and other cool features. Let’s watch the video: Photos: More photos on Flickr.com: https://www.flickr.com/photos/141718063@N06/albums/72157687306220840 The building instructions: https://rebrickable.com/mocs/MOC-22024/desert752/merlo-roto-telehandler/#comments Thanks for watching! I hope you like it :)

I've filmed short review of this model. Sorry for bad English - I have no practice for a long time. I hope I'll fix this problem in the future :) WUQ

Hi! After long break I’ve finished new model – it’s a 4x4 Crawler. I has 4x L-motors for drive and two M-motors for independent steering. This model isn’t separate project. I am working under new huge MOC and I just liked the chassis and wanted to create a crawler on it :) The model has non-Lego tires. It was bad idea to use IR receivers and to film in sunny day so it will be a lot of shadows in the movie: Some photos of my little monster: Short review: Thanks for watching!

Thanks for positive comments! :)

Hi! Today I'd like to show my funny steampunk truck. It was created just for fun - not for real off-road :) Short video: Thanks for watching!

Very nice loader! Outriggers are awesome!

Yes! I'm short of time now but I've started building instructions creation.

Small off-road addition for this model :)

That's awesome!!!

Hi! I’ve translated my review of 8880 set (B-model). I need your feedback – is it interesting for you? It's not too complex model and video is quite short that's why I've chosen it for my experiment. I have a lot of cool old sets (reviewed and not reviewed) and I can translate some of them. Thanks for watching!

Very funny video and awesome model!!!

Very nice dog but I can't open a video - can you upload it on YouTube?

Thanks! I'm glad you like my pets :)

Hi! These two off-roaders were made special for Moscow Technic fest (November 2016). Hedgehog: Chick: Thanks for watching!

Amazing!!!
