TT's ZIS E154 Trial Truck @ Mazovia Grand Prix 2010

Lyyar posted

of a Lego Technic Trial Truck (TT) ZIS E154 built by "TT". It was driven at LUGPol's "Lego Truck Trial Mazovia Grand Prix 2010." There is no description accompanying the video, and I could not find any mention of it on the LUGPol forum (English translation), so could any LUGPol members tell us more about this MOC?

Great truck!

I hope to learn how to use my NXT set in trucks one day.

Nice one!

Not even does it look very good, but performs even better in the truck-trials

Great use of NXT, bluetooth and power functions too!

Well done sir!

Thank you for the link to the description page, Sariel

That truck truck really caught my eye when I saw the video of that TT race

I think it is the first time I see a Trial Truck with M-Motors for propulsion.

Okay, Mahjqa and Zblj made mini trucks with M-Motors but they were not of that usual 1:13 size.

btw: I wonder why so few people don't use NXT-servos for propulsion, the only one I know is yoraish, maybe it's because of some Trucktrial rules?

I agree. I never thought about using M Motors for propulsion, instead I used them only for steering. I guess with a worm gear it might work nicely because if its size.

TT's use of Bluetooth means that one doesn't have to crouch 2 meters away from your Trial Truck and block the infrared rays of the sun. His control diagram is interesting:

From the Polish-to-English translation that Sariel provided, TT wrote,

"Truck is equipped with two sets of NXT. One of them is a pilot. The control unit includes a fluid power control propulsion engines. Torsion coupled with a scoop on the remote control. And buttons to change gears. All parameters are displayed on the screen NXT. The big advantage is Bluetooth communication. The range is several meters, and has no impact on the sunlight.

"The second NXT system is built into the vehicle and manages all machine functions. Over the in-vehicle system is PF, which also controls the sensor to the NXT HiTechnic IRLink. To drive the two motors are built with FP medium with the gearbox on the last bridge. Transmission in a version had 4 gears and pneumatic control actuators four young triggering the two solenoid-operated two PF medium.

"In the second version of the gearbox with 3 gears. I managed to get rid of a bunch of gears. He was also removed all the pneumatic system, which replaced the one built into the NXT motor frame. The gear changes are mediated by tendon flex system (combine engine in the frame of the bridge).

"Torsion in the vehicle is operated by a motor mounted on the frame NXT. Dummy engine is powered by one engine PF medium."
