Update: --== DAGU ROCKS ==--


Update: NEW manual attached! Replacing old one. Sorry for the format, PDF was too heavy :)


 Hi dear fellow robot builders, members of LMR.

As I am sure you know, OddBot has made us some cool contact with Jack from China, the guy behind DAGU Electronics.

Now I also had some talks with Jack himself regarding a production of some of my stuff (Thanks Odd).

And I tell you, the guys at DAGU moves fast, sends money as promised, and the hardware is actually REALLY NICE! 

And I am NOT just saying this because he is supporting us, I have tried quite a lot of HW that people wanted me to promote on LMR, and it was not all that good ;)

However - now I just got this cool mail from he’s assistant, Claudia:

Dear Frits,
How about these days?
This time I'll show you a great kit, named Mr. Basic, consisting of a aluminum alloy chassis with an extension PCB, which provides a reliable expand platform for DO-IT-YOURSELF. You can find the photos of it in attached files.
So far, we just have Chinese package for Mr. Basic, but there are English user manuals, so everybody can assemble it with his own hands depending on the manuals.
For Chinese market, our original idea is letting all robot hobbyists can create their own robots with our Mr.Basic.So Jack thinks this product will also be a good choice for the members from LMR.
We are excited about your idea about "LMR members editon", so we would like to offer 50 sets Mr. Basic printed with LMR logo with a special price only for LMR members, it just cost them 22USD($15 per set and another $ 7 for shipment) to own one. Every member who bought one and designed a new variation can put their creatures on LMR, and you can let other members and users vote out three best ones, each winner will be offered $100 from DAGU as prize.
What do you think about the above idea? Hopefully waiting for your respond.
Kind Regards,
Claudia

 Electronics are easy. Hacking servos to continious are easy too. Forget all those gears and axles. Opinion. Simple is best especially with mixed up parts. I have see a few nylon pinion gears split in my day. Should be brass for indurance. Not easy to replace.

Can you still ordre this nice looking kit?

See top menu for where to buy stuff / components :)

Thanks Frits this helped alot when building Mr.basic since the instructions are in japanese.

Check the teeth on the crown gear of one of my rear wheel axles. (The piece of black plastic is mine - for contrast.)

As you can see, two teeth are broken off. I do not know if this is the result from racing around or if they came like that. Just wanted to warn you all. Check those teeth. Every one of them. It's not too late to ask Claudia for new axles.

As a result of the broken teeth, the gears do not mesh very smoothly. And I fear the loss of more teeth should I make Mr Basic do some more doughnuts

Mine had the dreaded poorly threaded axle shafts but overall, I don't think it is terrible.  The drive shafts do worry me a bit but I don't think they are a show stopper.  I've seen RC car kits costing much more with similar problems. 

Overall, I'm happy with it. Plus, the way they are willing to own up to the problem and rectify it carries a lot of weight with me.

Someone mentioned their front wheels not being driven because the gears did not mesh. I had this problem as well since I was forced to abandon the spacers on the axle. I found my spacers were too small to go over the shaft even with the burs removed but since there is a nut behind the wheel I decided this was not too important. The downside was the front gears not meshing. I put some 3mm washers behind the crown gear to take up the slack and now it meshes fine. I used some superglue to prevent my nuts coming loose on the axles.

I have had the opposite problem. The crown gears were not placed far enough onto the shafts. The bit of shaft sticking out was barely sufficient to hold on to the Alu T-shaped bearing. Only halfway into the 1mm plate.  I tried to *carefully* tap the shaft further down the gear, but feared ruining the whole thing.

Maybe I get braver with spare parts in the mail...

No, still sober. I mustered the courage to tap my axles further down the gears. Here's a photo. First axle (on the left) is done.

The end of the shaft sticking out at the far end is 2.6 mm long. You can see some burring on the shaft near the gear. That's probably designed to be there, gripping into the plastic.

My tapping caused the entire shaft to  shift exactly 1.0 mm. It now sits nicely in the hole in the aluminium axle holder. I had to rearrange all the other parts to move 1.0 mm as well. Towards the outside of Mr Basic. There is sufficient length left for this surgery. The wheel can still be bolted on. I had to resolder my inner nut of course. But that is just my problem.

I had the same problem and thought about the same fix. I was a little unimpressed with the kits quality. I had a few nuts that were drilled off center, others had a glob of something on them that got in the way of threading them. The little black set screws barely fit on the allen wrench so I had to tinker with them to get them set. I doubt I would buy another Mr Basic kit or recommend it, but the price was right to try it out.
