Meyra Optimus 2

[grum64]

Hi

Sorry about the less than helpful topic title but let's face it, there's only one Lego Wheelchair in this forum.

I've been trying to build a Lego wheelchair for a while but haven't been happy with the results so thought I'd try LDD.  I've not used LDD very much at all so this was very much a case of learning on the job.

This time instead of 'building' a self propelled 'chair I thought I'd have a go at a copy of my Meyra Optimus 2 electric wheelchair. Here's a couple of pics:

I've enjoyed getting to grips with LDD but can't say I'm entirely happy with the results. 

This'll be my first MOC and isn't to scale, I've just done it by eye. I think it's a 2-4 studs too wide but I'm hampered by the wheel size I'll try & sort it out during the build. Also, I'm not very happy with the side bodywork between the wheels & the area between the front wheels. The top box is a bit too big & not 'very elegant' so will also be redesigned.

It'll have PF, with an XL motor for drive and an M motor for the rear wheel steering. The AAA battery box is situated under the seat which, when the topbox is swung out, tips back for access. The receiver is sited in the topbox (though not on the pics above, my chair now has a top box).

I'm now ready to build it but thought first I'd post the LDD screenshots to see what you think.

I'd appreciate any constructive criticism.

It looks very good.

As you say it would be good if you couls shave off two stud's on ether side.

You may need to check out too see if you have enough room to do this as It looks like the suspension may be in the way.

It looks good , but there may not be enough room inside for the Lego Power Functions elements. You could use a tether control, where a motor is driven by a Power Functions Extension cable connected to a Battery Box outside of the model....

The battery box is under the seat and the receiver is behind the seat.

My knight in shinning armour... I panicked for a moment wondering what I'd done wrong.

Thanks for 'the save'.

Best Grum64,

Your Wheelchair looks good, and when you build it at a little bigger scale you get more room for all the technic inside

Thank you.

This is the MK1 version. I think I'll build it 'as is' just to see how I've done using LDD.

I'm working on the next version on LDD. As you suggest, it'll be bigger, I'm thinking, about half as big again but this time I'd like to get it looking little more to scale.

This is a pretty phenonemal build for a first MOC, grum64, very ambitious. I really like your treatment of the base at the front, I haven't seen this before and I bet it will look great. If you want to go for greater accuracy, all those intriguing curves on the base would probably be best handled in system rather than technic, though it would reduce your space for the battery box and motor. Looking forward to the finished build. Good luck!

Hello Again

Great to hear from you & thank you for your kind comments.

The base at the front, I presume you mean between the front wheels, is a bit of a work in progress, I'm now working on the LDD MK 2 version which has these pieces replaced with a couple of 11 x 3 Quarter Cylinder Fairing Panels (62531). I'm still not sure which looks better.

I've also changed the design of the top box. It's now 4 studs narrower and less angular, it still contains the receiver. I'm hoping to install front and rear PF LED lights operated by a PF switch mounted under the seat. This way they're not on all the time extending battery life.

When I've finished the changes I'll upload the photos, hopefully it shouldn't be too long.

Look forward to seeing what you think.
