Would you guys like to meet up on Tuesday to see it, discuss other things etc...
We can meet on Monday as well, i personally think we should meet next week.

I am making the chassis and steering system. I have cut the parts, but could really use the disc/belt sanders at uni before assembly. Hence i will be in likely on monday and tuesday.

Below is the graphic i was talking about, lets have something like this:



peace out rabbit

tyre and rim

hey guys check out the final tyre and rim
thanks for helping me out with the tyre scottie :)

Logo / Logotype

I am seriously liking the name toro, followed by its power output eg 1200w...



Our concept in action! (Although way too big a farm space =p)

MISC / CABIN / LOGO

Hey there guys, Scottie and Rob good job boys!
1) Scottie your pillar mounted controls are popular in agri
2) Rob your idea of turtle and hare icons is also popular for speed control

see below images:



Check this bad boy! (New Holland)
** note how the mirrors are attached.


Also here are some logos of AGRI / TRUCK manufacturers, to aid in our logo design. If anyone has any ideas, sketch em'

seat

hope u guys liked it ;þ

Names + Images

Taurus Spanish = Tauro
Minotaur
Bull Spanish = Toro
Dart
Pug
Pug Spanish = Arcilla
Tank Spanish = Tanque
Comet Spanish = Cometa
Pick up Spanish = Recoja

Inspired by our “tough” block-esque form, almost pug / tank like.
Any ideas, blog it in the comments = )

** Digits seem to be the most popular “branding tool” used to divide agricultural equipment e.g. 6030 Premium Series (John Deere), RM-308B (Cat), MF 6400 Series (Masey Ferguson)

Presentation / Misc

Nice work robbie, how are you going?

Dudes i was trying to think of a name for our vehicle and looked at this company
Samedeutz. The names for there range are listed below:
Solaris
Argon Classic
Dorado
Frutteto II
Krypton F
Explorer T

What do you boys think of naming our vehicle similar to the above except in spanish, the national language of C.R

I was also curious as to how agricultural equipment is marketed, so i started at the top with Lamborghini, John Deere etc, and i found this link...
http://kevenker.wordpress.com/tag/costa-rica/

a guys blog, with wicked photos of C.R farms etc...
a further note, i was thinking i can render the vehicle, and super impose it doing some farming duties, on the C.Rican hillsides! How cool would that look!

Excellent choice of tyres boys, i have been reading that tractor book and that tyre size, and our pattern are such that they minimize soil compaction, i have also read into farming methods, ploughing, harvesting even forestry this book rocks! With this we can justify our design, and all its features! sweet as!

**also some tractors from the mid 60's to early 80's feature umbrellas! used only to provide shade, something farmers are familiar with.

B E L O W I M A G E
**In the tractor book, some tractors have 2 even three sets of wheels, mounted to spread the load and cause less soil damage... they can be seen clearly driving over their crops, not in furrows. Plus what do you think of the colour (this is the older model)

chassis

Boys boys boys, check the chassis!

In my mind i thought the cabin could be pressed steel, just like a car body, but i could not work around how it would mount to the chassis. The pressed steel cabin would also be heavy so i made the "upper region" of the chassis integral with the lower, make the muv stronger as well as, letting the cabin be made up of bodywork!

lighter and easier to manufacture > CHEAPER TO BUY!!!

scale

hey robbotheyobbo :P
i have succesfully scaled the model up to the exact 1:8 (after 784 attempts/crashes --> i beat u solidworks!! huahaha)
but the file was huge 22mb so i couldnt send it through email
what if I put it in drawings say A3 page for each view with dimensions so we can show it to simon and hopefully hed sign the modelling thingy
r u gonna be in the city tomoz?

FITS!!!

The tyre fits pefectly, only needing to be scaled' hoorah!!!
thanx dan wicked job! =)

** in the view you can see the Li-Ion cells integral with the chassis **

Mechanical Underpinnings

How resolved do we want the chassis, the mechanical underpinnings of the EV

Steering and engines

Boys good news on the specs for the steering and engines

I M P O R T A N T
** MUV using Lithium Ion rechargable cells.

** I would love to have the engines inside the wheel, but havnt found alot of info in regards to the specifics. Simon wants specifics, and i have found two examples of suitable electric propulsion systems.

** i propose we mount two engines in the chassis (driver sits on top of battery cells)

hub mounted motors, hydraulic steering,

It may be innovative, no physical linkage means more space but hub mounted engines make changing tyres difficult. Keeping it simple means using existing rime for our tyre. Also hydraulic steering takes up floor space for pumps etc... a electric steering system (still steer by wire)is more practical and robust.
Hydraulic steering will need either big pumps or use alot of power to push pull wheels, a complex system. Easier to use a tried and tested electric/motor assisted steering, plus it runs directly of the fuel cells, PTO uses rear shaft engaged only when needed with a clutch. Simple

SOLAR SHADE

Dan man, here are the pics of what simon drew...
hope it helps.

Solar shade

Thanks for the mail dan, and sorry mate i will blog the images tommorow morning before 8.00am (Sat)

in regards to the motor progress

http://www.currietech.com.au/part_motor.shtml?openmenu=11

Large brushless hub motors seem to be the favourite so far...

if you guys post anything i wont be able to comment back till tommorow evening (sat) as i am at work all day. Enjoy the weekend boys, whatever you may have planned.

lindsay (yes/no?)
I will do some tonight, scottie if you wanted to do this, cos you knew alot about the dc/brushless system thats cool. Ill simply forward you what i find

Scottie, also? based on you are familiar with rekopel (correct spelling? recycled ABS, would you be keen?

BODY/CAB: Steel (after simons chat)
CHASSIS: Steel " "
TRAY: Rekopel, high density polyethelene
WINDOWS: polycarbonate (Lexan)
BUMPERS: Rubber elastomer / urethane? (same as the bumper on the siemens white trams, can be coloured...)

(CAD with dimensions)
>> Robbie, seeing that you are in charge of the model, would you like to derive dimensions from the cad files?

**I think i can stop cad (steering) and pull up info on the motors, do materials or interior... i am happy to do any, please post.

** Dan is designing the solarshade (what a cool name!)

Steering

thanks for the post rob,

Here is an overview showing how the steering works, it is possible to use compressed air instead of hydraulic fluid...

the individual pumps a elecric assisted, hence we have steering control (steer by wire)

if you dont like it or think it is too complex, let me know.

Good Work

Hey boys, im glad you all like how the muv has shaped up!
Its all your input that made it possible.

I am working on the hydraulic system... its all good.. bit of work though integrating drive/steer by wire with hydraulic actuation, the result will be a a well refined system worthy of a medal!

Such a system is innovation all on its own.

** Would someone like to cad the roof/solar shade.

any further suggestions are more than welcome, be it handles, lights etc

Thanks guys. Lindsay

technical details, hydraulic steering and pto

Dudes i a mworking on the hydro's and Pto installment...

sadly i only have this poo image to show my progress i wll work more on it tommorow morning

CAD

updates 2 of 2

Updates 1 of 2

Here are some pics of the new cad model... enjoy

Only detail cad remains, that is
1) drawer side storage (instead of bins)
2) handles
3) lights
4) cabin
5) pto
6) steering
7) steering cuts

**one step at a time dot point at a time, they wont take as long as this stinit of CAD

any suggestions would be great,
when does this need to be done?
can it be done by friday?

i will endeavour to have the model completed, that is have all the above points addresses by 3.00pm tommorow (i have to leave for work)

revisions @12.07pm 11.10.06

mirrors, and tray top indent and main cavity.

Revised guards

Cheers rob, here is the new guard
nb it has not been trimmed...

tyre

hey fellas
we're using this tyre 230/95R32
(width 230mm diameter 32inch=800mm)

hope u liked it :)

what about the motors?

we havent decided have we?

HMMMMM

Hey boys, this is what scotties idea mudguard looks mixed with the housed out section for seating and additional storage....
what do you think?

i personally do not like it... i just dont think it works... let me know what you reckon....

I will work cad the front section untill then

CAD Progress

Hey dudes, im working hard on the new CAD model, wont go to bed till its done! ill post a few pics and email the file when it is complete.

cheers

CAD progress_steering @10.11pm 10.10.06

Hey dudes, this is visually how the steering works with the integrated mudguards and light assembly.

Further CAD progress @ 8.59pm 10.10.06

cad progress @ 8.11PM 10.10.06

CAD

For tommorow i will have a cad model of the MUV, it will look and share the same dimensions of the orthogonal post.

If anyone wants to, go right ahead and do (design and or cad) the interior.

Orthogonal

Here it is... let me explain

1) front wheels have mudguards which also house lighting (headlights and indicators)
2) indicators are also on rear view mirrors, maximise visibility and flash when muv, or pto is in use.
3) tray is 1100mm long cabin 900mm
4) tray is made of high density plastic and extends to form rear mud guards
5) "roof rack" a separate modular attachment that is left off to maximise tray capacity.
6) rear lights (brake and indicator) integral with tray
7) rear view mirrors mounte on front window pillars



SCALE: This was done as an overlay of the "block model". The block model was created in solidworks with dimensions as accurate as possible in relation to tyre size and cabin space.

i will email you guys the block model (files and assm)
