HW Name Unknown

[J.A.G]

I'm starting to build a HW spinner robot and thought I'll start a build diary.I have no drawings I'm going to make it up as I go along I'm using mobility scooter motors

Will post photos tomorrow as my phone don't let me upload photos on this website

I urge you to be VERY careful with the spinner. Spinners, along with flippers, are the two easiest ways to kill or injure yourself or someone else. Spinners can project high velocity chunks of metal for surprising distances. When testing it's important to ensure that nothing can escape the test area and that you are protected if something fails

Yes I do have common sense but thank you for your reply

[Eventorizon]

If you are planning to use the 2 halfs of the pneumatic tank as your spinner, as you have on your Facebook page, then I will be running the other way as fast as I can.

Sorry for being blunt but this is not just unsafe but downright dangerous. There is no way you would ever pass a tech check let alone be allowed to spin it up.

While its great to be using things you already have and was very much in the spirit of the original robots on the show, this just isn't safe. At all.

Well for start it's not finished and I can't see a problem after all you weld spikes on to spinners what the difference

Welding spikes to a spinner. Wasn't a succes in the past.
Never seen done it right. I prefer monoblock spinners.

Just spoke to a person who is on robot wars series 8 and said it will be fine as long the weld are strong that's ok I do welding for a living

Have you seen some of the robots that qualified? - ones made of MDF with a petrol engine and lipos.... aka a bomb.

Honestly just being in the new series of RW is not a stamp of competence or quality.

The other problem is you're putting all your eggs in the being accepted into RW basket. Season 2 applications will be hugely competitive and the chances of getting on for most teams won't be great. It's simply a matter of numbers. You're likely to end up with a heavy you'll not be able to run.

You mean it doesn't bother you you that the weapon could break in half along the join and go whizzing across the room and smash into something? Or that since those tanks are probably made of mild steel that 1 good hit will twist them irreparably, ripping itself from its mounts and again breaking free of its mounts.
Also welding your teeth on doesn't work. The forces are too great. Your welds WILL shear. You must dovetail or bolt them in with extra support and even that isn't reliable. If you hit something and they break off those chunks will be going fast enough to kill you if they hit you.

Of course it doesnt Alex, he has "common sense" :P

Well that's not very smart is it like I said common sense

Season 2 will be way more competitive to get into.

Building a HW spinner for a first bot goes against common sense. As does 2 halves of a pneumatic cylinder welded together to make a disc.

So? Being a pro welder* doesn't mean you know about the forces involved in a decent spinner.

A good weld is stronger than the base material.
But it still is a connection, and you need to balance the whole too. Welds and balancing are not easy.
Not something done by a gardenshed builder with a drill , anglegrinder and a MIG.

Talking to a guy on the RW8 filming doesn't make you an expert either, nor does the fact somebody is working for a TV company makes that person an expert on anything related to robots.

I was there during series 5-6 and 7.
Most Tech-checkers and technical advisors were competent people. But anybody on the filming or catering crew, not so.

*wanna go into a bragging fight about pro-welding?
