I suppose that makes sense now you mention it.
I've been massively inspired by the Team Bitza wooden robots and Johnny 2x4
Just been for a look on youtube. Ok, I take it all back apart from the MDF :)
It's an odd decision to have the wheels so close together, it may make driving difficult (either hard to go in a straight line or hard to turn- can't remember which!) but it should be ok for a bit of fun.
Erm yeah the wheels are close together to make it mental to drive, sort of so it just bounces round the arena causing pandemonium.
Some more pictures, I have some brackets that I've made but I've yet to pull it all together and get pictures of it all together. I'm basically waiting for another pack of the main bolts to turn up. It holds it all together but they'll be another fortnight or so.

Just thought I would say the top panel isn't sat square in the second picture! When it's on properly it sits square and flush covering the whole top! Thinking about calling it Wabbajack after my favourite Skyrim weapon lol.
I'm not quite sure why, but I can see those rubbery corner-protectors for keeping kids safe from tables etc on each corner to cushion it lol
That's a really good idea lol. I like the way you're on the same wacky out the box wavelength lol. :)
I have a bit more to add about Wabbajack.
Items started to get bolted down (drive pod removed for access)

The lid marked and ready to drill.

This has a bit of the home-brew shock mounts I've been trying.

And again with the speed controller lol.

And the big box of fresh bolts that arrived so I can carry on cutting and drilling the lid.

Next plans over the next few days are to start looking at making the removable link and some sort of bracketry for that. This also sort of ties in with wanting to start wiring at the weekend as well. I do a lot of wiring etc with work so imagine the cabling will come on quite quick once I get started. It'd be nice to have it running by the middle of the summer. I also need to order a Tx/Rx at some point as well.
I also have plans for an ant and a heavy version of Wabbajack, will see how this goes first! Any thoughts/questions/oppinions welcome to liven up the thread!!
It's running! Don't have a great name for it yet (answers on a post card lol). I've tried it up and down the drive and taken a layer off the laminate and it works great!
Obviously the old girl needs the lid bolting down and a rewire but the basics are there. It's really fast!

Sorry for the naff video it's really hard driving and video-ing at the same time!
To post the postcard, I'd need a stamp. Why not put a picture of the Queen's head on the top panel and call it Giant Postage Stamp (GPS for short ;)). The proportions seem about right for it.Quote:

Squared
or a small 2 on the top right corner of the robot :)
These are awesome ideas!
It drives really nice, I was really surprised by how smooth it is and everything.
I'm gonna have a good go with it tonight and I'm worried about the straight line side of it lol.
I was really into driving the robot round last weekend, but a few things came up. The bolts caught on the floor and the ground clearance wasn't the best. I messed about till mid-week trying to tidy bolts and stuff up before I decided to start on a fresh body shell. Same design, just screwed and cleaned up. I've nearly finished the body and I'm in the process of transferring everything over.
It's a lot more in proportion and I've done away with the MDF. I now have 12mm marine ply for the top and bottom and 2x2 for the sides. The gap between the body and lid is deliberate, I plan to have LED strips all the way round the gap to look snazzy lol. There's a 10mm spacer that will sit round the top of the body allowing for the link holder and LED strips.

The lid needs tidying up as it's a tiny bit too big and stuff but I was excited to get it together to see how it looked.
Bit of a naff update compared to the other robots on here.
Made random trim and started wiring properly. Also had a go at making a random toolbox (needs a better handle and straightening out).

Had the brain wave today of doing away with the naff lid and building a big lifting arm for the top instead. I could power it with a juicy linear actuator from Mr Gimson.
The CAD department knocked this up for me to bung on here.
A grabber and a lifter. It'll be as shonky as the rest of the robot I'm pleased to announce.

Thought I would bring this up to date. I've built the running gear onto a plate that can be moved as a "module" from shell to shell. This obviously works for me as I have little fabrication skills other than keeping battered cars on the road and building street luges for my 4 year old. Therefore, I'm largely aware that my robot is like a hermit crab, constantly looking for the next shell in which to stow it's behind. To this end, we (I say we, I mean me, my crazed father and a 4 yr old) decided the best thing to do would be to screw everything to a bit of plastic. Then, which ever shell presents itself we can bolt said plastic into and away we go. All this method requires is steady supply of scrap and rubbish (of which there is plenty in Blackpool).
So please see below picture of our new "module". This can be bolted into any given shell and will quite happily run round the house on its own. The wooden shell pictured above broke up after a weekend of fighting a Tamiya Fighter Buggy. I don't have a picture as of yet of the new metal shell, however it's based on a money tin 30x30cm and about 2 inches deep. The below module bolts in nicely provided you cut a pair of wheel slots and bolt holes. This week I will finish it's new body off and slap up a picture. I'm trying to enquire as to how I get us to the Doncaster Dome event in September?? which would appear to be a non spinner event.
All comments and slagging off's welcome / encouraged :)

Ok! After months and months of trial and error, we have our design that we're going to stick with for a couple of years! There is a body shell being made from Ally/Steel at the minute, and also a new base plate being made as this is a chopping board. But at least you get the idea. Meet Rag N Bone.

First run! Going well round the kitchen!

It has a roof!! Its making me laugh how battered the stuff I make looks even before it's had a fight! A by-product of using recycled bits I suppose :D I'm thinking about making some sides and giving it a lick of paint, umming and arring about bright pink or orange!

Looks great so far, but some side protection may be advisable to protect against horizontal spinners.
Thanks for the reply! I'm making some side bumpers that will cover up the wheels and open gaps etc. I ran out of angle after making one so just on the scavenge for a bit more from somewhere lol :)
I'm not planning on entering against spinners, I know this wouldn't be strong enough and I see that as the upper levels of robot fighting. I'm planning on entering this next year in some random events and if I do fairly ok I'll build something hardcore to come and batter the spinners with :D
I really need to learn to weld.
Managed to scavenge some more angle. The more I add to the robot the worse it gets haha. Anyway, side bumpers added. 12V LED is on the way, cash is moving to Paypal for a Robochallenge removable link and I'm going to buy some paint for it on Friday. I'm planning on painting it lime green or orange over the weekend. At the weekend I'm also going to sign up to the Doncaster Dome event and will be coming along with my brother and his friend as part of my team lol as the old man is on holiday. Oh and we've been bidding on a lecky wheel chair and have obtained an empty CO2 fire extinguisher bottle! Latest pic of ramshackleness...and potty. And stray socket set. Oh and I've started shortening bolts! Also I've become a paid up member of the FRA!

If you're looking at a good paint job, I would suggest doing the body in green. Paint the spear red and continue a red stripe running over the top, then it would match the tyres.
That sounds really cool! I was going to leave it as-is but decided it looks too much of a state to not paint it lol. I'd thought about black with neon green highlights like Karkas
That's not a bad idea. Were you still planning on putting lights inside it?
Yeah was thinking about it but I would also need proper LED's as a power indicator.
Fair enough.
I forgot to ask, how did you come up with the name?
Rag N' Bone? Erm my team is Skipdiving Robotics as everything is made from found parts or pulled out of bins so thought I needed rubbish based names lol. We used to have rag n bone men driving about n they collected scrap n the name sounded narly...well sort of :). Future names maybe surplus special and scrapdaddy but think thats taken lol.
How is your robot going?
Well I know Scrapdaddy was a Battlebots entry, so it's definitely taken. What about 'Rig of the dump' or 'Trashcan wallop'?
My bot's going fairly well, although it hasn't been without problems. I've had to get a new charger due to the first one being internally damaged, but that's not a big deal. I've decided to use my remaining weight allowance on a removable second layer of armour. It was going to be all steel, but I've had to use aluminium for the back and sides in order to stay within the weight limit.
On the plus side, I've started putting my artistic skills to good use on the lid!

That's really cool. I was going to look into buying a kit but got worried that if something got mangled I'm constantly be on the phone to the sellers etc with my wallet out. As shonky as my robot is at least if something gets mangled I hack up a bit of chopping board or the side of another pc to make a lid. But I really like those kits. I've come close to buying one a few times. Nice paint job by the way!
I know what you mean. That's the main reason for the second skin, so that the robot should at least be able to make it through one match before the opponent can reach anything vital. Not to mention it's easily replaceable.
Thanks for the compliment!
Yeah that's a good idea. I didn't get that far when I was hammering my shell into shape over the back step. Ghetto engineering at it's best :D I really like your paint job though it's awesome. I've got as far as spraying my body with undercoat lol.
Sometimes the ghetto way is indeed the best! I must admit, I have a slight advantage in that I work as a metal fabricator, so I have access to sheet metal and the equipment for cutting and bending it however I want. But I really admire people who don't let lack of resources stand in their way!
And in case you're curious about the paint job, I haven't even finished yet. I just wanted it to look dark and demonic, hence the robot's name; It's half Japanese, half Spanish, and literally means 'shadow machine'.
Your name is well cool! Are you still coming to Doncaster Dome? How are you planning to attach the metal to the plastic body? (always up for nicking ideas!)
I'm definitely still coming to Doncaster, I've come too far to miss this opportunity!
As for the armour, I'm making the metal shell separately (since it's bigger and encloses the wheels), then attaching it into the original screwholes used for the plastic lid. Here's what it looks like with the shell on.

Looks like a pretty good first robot Dan :)
Thanks :)
