THE LONG WALK!!

Just to keep you up to date

Pictures of the 6 legs finished only 2 to finish and some of the bracket assembly to connect the legs to the pod. These I have made adjustable so I can vary the distance from the crank to the leg pivot I think this dimension will be quite critical and I don't know exactly what it should be!!

I have found this project so far to be very interesting to do I hope the result will be entertaining for whoever watches it go. :D

It's all happening at the moment!!!

That's some hypnotic leg movement 8)

Well done Craig, the build seems to be coming along really well! Best of luck for the rest of it :)

i could stare at those moving legs for ages lol

how much longer do you think the walker will take you to make?

Hi to answer your question on how long it will take. I hope to get the first pod to a stage that all 4 legs will operate with a cobbled up battery by next week. :crazy: :crazy: :crazy:
If I can keep working on it through most of August I hope to get the second pod going. :shock:

I have a feeling the robot will never be €œfinished€, as I will probably keep adding bits for years to come but I want it to be sort of ready for the winter tour. :D :D :D

I think with all 4 sets of legs going it will be quite hypnotic :shock: :shock:

those legs do have a certain hypnotic factor, this is a really interesting build , but this isnt going to compete as a fighting robot right ? As part of the brighton robotics club im building a dinky 2 servo walker , give ya a race :rofl: .

Hi Walker lovers
This is the first test of Arac mk 3....legs are still a bit wobbley...but its just the joints that need tightening,,,anyway you will get the idea...

Is that gear-crow a walker too? Are there any videos of it? I saw it on the mutant robots website and started to wonder if this thing ever worked?

Froggy

That is a realy nice walker.

Is it all new or made of bits from the MkII Arac bot?

Hope to see it soon

are you going to any events this year?

Hi Craig
Many thanks for kind words...The Mk 3 ARAC...is a cut down, much lighter version...the legs and levers all come from the mk 2 bot (no way was i gonna go thru all that again !!)
The body and internals are all new....i have lost the jaws and tail mechanisms to make it much lighter also it is now powered by 2 wheelchair motors as opposed to 4. It now not only looks good ...the bloody thing works !!! and takes up much less room in the trailer.

Cheers Froggy

Watching your robot€™s weight seems to always be the problem. With my walker the weight seems to increase to a point where I will be drilling loads of holes soon if things don€™t level out, I was hoping to keep the robot to about 60Kg but it will be more like 75Kg I think. Plus the motors I bought will be too small so like you I am looking for a couple of wheelchair motors for the project soon.
Also because of the extra leg length on my type of design, I will have to stiffen them too (more weight) and so the long walk continues. :D

no quiet tha same but http://www.flickr.com/photos/tanto818/3853298260/

Hi Craig
Hope things aren€™t too bad at the moment. Were still praying for good news for you.
Any walker qualifies! And your one works that€™s more than I can say for my effort at the moment I have been sorting out St Hammer, Tron and Seraphim plus the new heavy.
So far I have four legs on the first pod and most of the bits to make up the second pod the idea is to finish the walker then fix all the problems I will have, like legs too flexible or the links not quite the right length motor not powerful enough this sort of thing. :crazy: :crazy:

Hope to see you soon


Craig

Have started chemo and first results are positive only up from here (I Hope)

happy Brithday too Craig only the best are Virgos :)

Vee is pretty cool actually its been something to do while I've not been able to get in the shed

slight update

Love the hair!

Some pics on the Pilgrim walker

It is getting there slowly!!!

Hi Guys
While awaiting bronze bushes to arrive (many thanks Mario) to get the legs walking properly...i have continued the silly constructions..so we now have scanning blue spotlight eyes....blue LED light show running from front to back...and a posion venom spiitting system.....(water pistol)... Wot fun !!!

Cheers Froggy

You know I was looking at this walker and thinking if I get the time I might make a Feather walker using this same mechanism, as I think it is about as robust as they come. The legs out of HDPE and the gears well in the body of the machine it would have to have a self righting system. Probably an electric Axe would be fun!!! :mrgreen: :mrgreen: :mrgreen: :mrgreen:

If you do build the feather walker then a hammer mechanism like this would be awesome:

That'll pack a nasty punch :twisted:

Pretty sure that's not allowed, as it's basically a cam walker - the legs are powered directly off a unidirectional rotational mechanism.

Hi Nick

I would call that a walker :uhoh: :uhoh:
As the legs support the whole weight, and the legs leave the ground to take the next step in a linier motion. :proud: :proud:
I can€™t see the problem, but this is a job for the FRA to rule so lets see what they say. :?: :?:

What do others think about this? :idea: :idea: :idea:

To be honest with you I think it's a shuffler but if it is allowed then putting the slide rails in the legs would mean less sticking out the top of it.

It looks similar to the mechanism used on scuttle off of technogames which was insanely fast (but still not a walker in my book.)

Just wondering dose anyone have or know of a two-channel speed controller, that can handle about 25 amps @36volts. I have decided to over volt the motors I have, and see how they perform even if I don€™t use this voltage for The Pilgrim I would like the option I know the sabertooth which I was going to use is only up to 24v thanks.

http://www.robotmarketplace.com/products/RS-RS80D.html ?

Only other option I can think of in a single unit is a Vantec, I don't know if the Scorpions will handle 36v?

Hi Joey
I had thought of that one but it is a bit too powerful there must be a smaller unit that can take 36v perhaps for some featherweights use a speed controller that takes 36v or more.

i use the rs80d in a featherweight nice thing if you have the room

going to use it probs for a heavy weight one day

the feather is in bits atm though going to add an axe to it:)

RS80d were do i get them from and how much are they please :D

Here are some pics of the two pods together so you get an idea of the type of thing it is :uhoh:


http://s569.photobucket.com/albums/ss13 ... GA5126.jpg

the next task is working out how to connect the two pods without getting the legs messed up!!

That's looking fantastic, Craig. Can't wait to see it in action, bravo.

The robot is looking awesome. What is it going to be promoting exactly?

A promotional device can be used to promote almost anything but the two main reasons are: -
1/ About a year ago we lost our youngest child Nathan, he was bourn with a thing called Edwards Syndrome. We were cared for by the Helen and Douglas House Hospice, their work and help at this difficult time was invaluable to us as a family. A father who has had to carry his baby son€™s coffin to the front of the church has experienced a pain that cannot be imagined and I would wish it on no one! So I want to make something that can be used to help raise awareness of their good work and raise some funds for them too. You can€™t run a heavy weight robot in a shopping centre as it may kill someone. But a slow walker with some posters on would be an interesting diversion to all the jaded shoppers on Saturday afternoon and they might put some money in the bucket.
2/ as discussed on other parts of the forum we, as a movement have to address the future. I initiated a thread on the subject a few months ago and one of the ideas I liked was to help the EOs to promote their shows, so I wanted to make this robot to help any EO with their promotion if they wanted it. We have to be seen to be known, TV is over so we as a movement have to promote ourselves by whatever means we can.
This is my effort, to everyone reading this what will be yours?

Now I'm feeling sad. I hope the promotion goes well for what is a worth while cause.

As for promoting combat robotics I have a pair of rumble robots that I have dismantled to make two driving bases and plan to make controlable from a distance (using long wires or some sort of cheap rc system, I'm undecided).

I was just going to use them personally for fun/ driving practice if I built a proper robot but I suppose they could be used as a promotional tool like the robochallenge mini arena (but rubbish and cheap)

Hi Craig

get them either form robotsolutions.com direct or robot market place

hope this helps

That's it I've made the frame for the two pods and painted it silver, as this seems to be the best colour for this robot. Here are a couple of pictures of the frame and the pods minus the legs at the moment.

http://s569.photobucket.com/albums/ss13 ... GA5137.jpg

The next part is to sort out the drive on the second pod this means I will have to wait for some parts through the post.

Dose anyone have a motor like the one in the picture (it says on the label Model MY7712 24V DC 11.6 amp 3400rpm) Technobots used to sell them but don't anymore.


http://s569.photobucket.com/albums/ss13 ... GA5140.jpg

There are also some pictures there of the robot with the frame fitted I walked the robot on just one side (thats why the drive broke!!!!)
It looked quite good with two new motors I hope to have a sort of working robot for Portsmouth.

If you can get a hold of Mike Hamilton Macey, I was on his website recently and he has those advertised, so it would be worth contacting him

Thanks Dave

Dose anyone have his web address?

Or dose anyone have a couple of wheel chair motors 24v or WHY. :uhoh: :uhoh: :uhoh:

i've not looked at this thred in a while, but the walker is comming along nicley:)

looking very good
