Can the title of this thread be changed to Engineering Project, it's misleading because there is a Junior Cert subject that is called Metalwork and has a Project too...

Ya, this year they've to make a Lunar Roving Vehicle (LRV), our school got the Brief today.. my first impression was that it was ok, until I realised that it has to be steered and powered by the front wheels. And each wheel has to be able to move independently.. so you'd be looking at three motors, all powered by 9V.

For me, that's the most difficult part. It's going to have to be light- acrylic or sheet metal. Looking forward to it though, it's not entirely different to the Snowmobile last year.

I was expecting it to be a lot worse after the snowmobile last year. It'll be a challenge but it leaves a lot up to your own design. Plenty of scope for creativity.

Ahh no? At no point does it say each wheel has to be able to move independently. It says the two front wheels have to be powered individually. I suggest having a wee read of the brief again before ye start building

"Include a steering mech. for the front wheels" front steering.

Brief: Design a model of a Lunar Roving Vehicle to the general specifications outlined below.

The LRV should:
a) Have propulsion units to provide individual drives for both front wheels;
b) Incorporate a central switching console to operate the front wheels;
c) Include a steering mechanism for the front wheels;
d) Have seating capacity for the driver only.

Presentation of the completed project should ensure that:
a) All main operating features are clearly visible without dismantling;
b) The longest dimension of the model must not exceed 350mm;
c) Electric power does not exceed 9V.

Will throw the rest up later!

God I would have loved this instead of the snowmobile I had to design/make last year.

A handy tip:
Get your brief finished over the mid term break, otherwise you'll be under huge pressure come March/April.
