K-cut source their own hardox for water cutting
Ah right, so you can specify a CAD design with a specification of what sort of material and thickness you are after and they water cut it? Fair enough, worth bearing in mind.
Yeah just send them a dxf or dwg drawing and they can cut it in pretty much anything. They have a lot of material on stock so best to ask them what thicknesses they have before designing something. For hardox I think it's 4,6,8,10,35,40mm
And now for something completely different.
Spent the past day and today working on one pair of motor mounts made out of HPDE scrapes. Hoping to get the other side done tomorrow and monday so I can have a working test platform to fully test the drive of Wolf-E.

Motors are now mounted and the wiring connected. Hopefully will get a test drive tomorrow.

So I went to do the test run and... the receiver is busted. I had to check both motors, both ESCs until I found the fault that was stopping both motors from running at the same time. It appears one of the channels used for drive on the receiver is not working. At least it's a cheap part to replace.
Pondering on drive configuration. Wither to go with gearboxes directly running the middle wheel and connect the front and rear wheels through pulleys.

Or run the brushless motors to the rear wheels with another pulley and then run pulleys to the middle and front wheels.

Personally I'd go with the first one, because a) it's harder to get high reduction out of pulleys (the gearbox will likely be much higher and won't slip) and b) I like Sewer Snake, and that's how they do it. :P
I had figured that would be a factor but I'll need to mod the gearboxes to have extended drive shafts to support the whole wheel and pulleys.Quote:

Don't Worry this thick-o work it out I had to set one of the mixes to -100% to get it to work
So I’ve been using Wolf-E’s test platform to help get a sense of scale with parts yet to be added such as the Lipo battery mocked up in cardboard.
I came to the conclusion that it’s possible to add 2 more 12volt motors and using HDPE. I can make a 4WD weaponless CSB instead of Wolf-E.

If you go weaponless remember that not every event will accept you - Insomnia rejected my completely finished pusher in favour or builds that had barely been started.
I already know about RoboChallenge's preference of active weapons, this version would be for live events and will gradually be upgraded until it reaches the more advanced design I have made of CSB.
You use two esc with bec. you should remove the red wire from on signal cable / connector.
Already done that.Quote:

Finally got to film CSB/ Wolf-E driving in my kitchen. Even though it's not ready for the arena, I'm very happy to have something working and moving about at this point. :proud:

Just a little animation showing the current conceived mechanism idea for the weapon.

Just out of interest, what software are you using for your CAD?
This isn't a CAD software it's actually a animation and modelling software called Autodesk Maya. I'm only using it cause my Mac can't run Fusion 360 which has been recommended to me before. I know it isn't really ideal for the job but it works for concepts.Quote:

Also I've been wondering in regards to the 6 wheel robot design and it's weapon linkage, how does one attach a lifter arm to a shaft? and how do you connect that same shaft to spur gear?
Tell you what, all the fully done bits so far look really neat an very solid, well done! Dont worry about upgrading to HDPE should run as is :talker:
not really solid given it's a test platform, the motors wobble slightly and the polycarb will not last long in battle so upgrading to the actual body made of HDPE is a must.
I meant the cardboard :lol: haha! Looks good none the less!
thanks
Finally made a new version of CSB's 2 wheeled design on the computer. In other news I got a sheet of 10mm thick HDPE for Xmas so when I get some new bolts and threaded inserts I'll hopefully have the HDPE parts of the body work finished sometime in the new year and then I'll worry about getting a Hardox panel for the wedge down the line.

That's like the ultimate wedge.
Is it? I think I'll be lucky to out-wedge and push bots about.Quote:

Comes down to traction really. You can have all the power in the world but if you can't put it down, it is of no use. Your design certainly looks fine, especially it it can run inverted.Quote:

Not sure how you see it as looking like Firestorm.Quote:

1. Thats alot of WKD bottle tops!
2. Ive got the same book, very good. Didn't know Dead Metal was a girl, the more you know.
3. Can I have a piece of chocolate orange?
4. Looks good, the cuts are really neat!
1) My gran parents have me a pack of 10 bottles for Xmas.Quote:

4) thanks the 10mm was easier then the 20mm.
Motors now fit into the bulkheads and now I’ve done a rough arrangement of the ESCs, power cables and the cardboard mock up of the Lipo battery. Still need to make the back of the motor mounts, get more 20mm HDPE to make the back plate. Once the threaded inserts and new bolts arrive I can start bolting the base to the bulkheads.

The FW is really coming together. Threaded inserts added to the bulkheads, now top and base plates are bolted on.

Motors are now fully mounted.

Looks very neat, your motor mounts are a darn sight more stable than mine are.
