Lego Volvo FL12 8x8 Trial Truck

Model of Volvo FL12, version 8x8. Features all wheel drive, 4 wheel steering with different steering lock, full double wishbone independent suspension, remote controlled 4-speed gearbox with neutral gear, working winch, working fake R6 piston engine and working steering wheel.

Vehicle is remotely controlled by mobile phone using Bluetooth connection. Both applications (mobile phone app and NXT app) are written by me in Java language (I used LeJOS to program NXT).

Volvo has 4 motors total:
- 1 NXT motor to steer wheels
- 2 NXT motors to shift gears
- 1 PF XL motor for propulsion (controlled by PF IRTower which is controlled by HiTechnic IRLink sensor which is controlled by NXT brick which is controlled by mobile phone which is controlled by me :)

This truck is designed to participate in Lego Truck Trial races GPM (Grand Prix Mazovia) 2010 that take place in Warsaw, Poland.

I saw in the recent TrTr video (LTTC 1/2011) that you changed the truck. * 1 NXT-motor for steering * 1NXT for propulsion * 1NXT for controlling the gearbox

I also think you made a whole new chassis. Will we be able to see some pictures or even a movie of it soon? Is the performance of it better ?

[AtrSvideos]

@ramacc0 you are observant. On LTTC 1/2011 I used 1 XL for propulsion and probably I'll add second one for the next race. Chassis is reinforced with 5x7 frames, also gearbox is one from Ural 43206. Performance is for sure better thanks to new chassis and gearbox.

Great suspention and ideas with the bluetooth. Could you possibly do that with a touchsccreen-only cell phone?

[AtrSvideos]

@Mr88high

It is possible but I don't think controlling the vehicle with it would be comfortable, or I just have not seen enough precise touchscreen.

Wow. I loved it when you flipped that other truck over! I really like how it has neutral and 4 speeds. Is the bluetooth more user-friendly than the IR remotes, i.e. not losing the signal?

[AtrSvideos]

@DuffLego Yes it is, you can control the vehicle that is up to 50 meters away in open space

@AtrSvideos I'm really a big fan of TrTr races and you are surely one of my favourites. Two XL's for propulsion is definitely a good choice, especially for a 8x8 vehicle. BTW:Pictures or a new video are coming soon?
