LEGO Car Prototype. Demo moving 90kg

[Burf2000]

So spent a couple of nights on this and was amazed it worked. I thought I would show a video for a laugh. Its far from finished and about to have a full rebuild.

I mainly built this to use up my Yellow Studded lol and to be faster than the wheelchair!

Uses EXOFORCE wheels and 16 XL motors

That's pretty cool.

I think the steering needs some more work,I was hearing backlash in the last video.

Whoa, Simon! Is your prototype a dry run for a Lego car like this?

I think if you have the LEGO, why not give it a go, bit of a buzz moving around in your own creation!

Very impressive :) Seeing as I weigh some 20 kg less, I should have thought of making one a long time ago ;)

Edit: 16 XL motors? OK, now I know what stopped me :) Also, now it's clear who bought all black Exoforce wheels off the Bricklink :P

Dont tell anyone but I am actually more like 85-87 KG depending on how well I stick to my diet lol. I think you should give it a go mate.

I would of brought them off bricklink if there was any on there! A friend helped me out with them.

I would of also used more than 16XL motors but I cant afford the rechargeable packs, I am already using 8 without steering.

p.s, brought your book!

Awesome work, Burf! As a child it was my dream to own enough Lego to do this...

Have you examined your axles after this? Is there any significant wear or bending?

[Burf2000]

Its funny you say that!, So took the whole thing apart last night and bare in mind I was testing and abusing it, I did not damage as much as I thought.

So I had used 4 32l axles to hold the wheels, these had become very screwed up due to some wheels getting jammed and some not. I have now gone for 8 16L axels so this does not happen.

Out of the 32 8 tooth gears, 1 had broken off and 1 had been damaged (same wheel). These got replaced and an extra set where added to each wheel (so 48 in total)

Small update

Redesigned the steering, now has a accelerator pedal and a seat. Steering is proportional to.

I see that you keep ignoring me... think small , the cat is thinking what the hell my human has done...

One day, finances allowing, I would enjoy attempting to build a life size, motorized, rideable, technic motorcycle.

That is ambitious!

The car looks nice anyway, you must be the reason why yellow beams in large quantities are expensive on Bricklink .

Awesome stuff, what gear ratio are you using for the driving motors? I would have thought it would require more than 16 XL motors.

[Burf2000]

A motorbike would be fun, a trike has been tried but failed (not by me). I got a lot of yellow beams off someone (swapping for polybags lol).

The gear is 1 to 5 at the moment (8 to 40t) however I really wanted it to be 1 to 3 however I ran out of room to put the motors and ran out of motors.
