Re: Team Microbots Build Diary

im 99% sure that is a claw i had made a while ago and if it is then its not ti its all mild steel

I also picked up Metal Beak's beak from Jamie at the event:

Lovely, 20cm long, 1.5mm welded Ti construction, 2.5mm Ti point, and it only cost a fiver ![/quote]

Re: Team Microbots Build Diary

I have to admit, I never have found Ti Box-section for sale , and the discoloration on the welds rather make me think about steel, than Ti.

Re: Team Microbots Build Diary

Touch a magnet against it, although if it's stainless then it won't attract either.

Re: Team Microbots Build Diary

The entire body is non-magnetic, but the tip is mild steel. Missed that in the original post, but no matter, a steel tip is better as it won't blunt as easily. It doesn't look like stainless, and it was advertised by Jamie as being Ti, and I trust him, so I do believe it's Ti.
While on the topic, how much force would the Gimsons 12v GLA6000 Linear Actuator produce if overvolted to 18v?

Re: Team Microbots Build Diary

Touch a grinder on it... If the sparks are white it's ti... But if you know the tips steel... It won't be... You can't weld stainless to ti.

Re: Team Microbots Build Diary

Or you could use a Mass Spectrometer.....

Re: Team Microbots Build Diary

Should get 600kg out of an overvolted one but probably not that much force at the tip due to mechanical loss etc, but even after that wont be half bad

Re: Team Microbots Build Diary

I spark tested it, IIRC It's not ti

Re: Team Microbots Build Diary

More like 900kg

Re: Team Microbots Build Diary

I was under the impression it was titanium, but from what's been said it's not sounding likely, in which case I apologise.

Re: Team Microbots Build Diary

Well, been a while since the last update, Project X is now retired. After realising that it had many faults, I decided to rebuild it, and for one last fling, I took it to the RoboChallenge open day and let Troublesome 2 finish it off (vid on my channel). The new model will be smaller, run off of a pair of LiPos and have steel plating instead of 10mm HDPE on top. As for Skyfall, the buying stage of the parts can start soon, now that my mum is happy I know enough about LiPos now . Updates on that to follow. On another note, I have successfully bought Chuck off Shane and will be running it at all future events.

Re: Team Microbots Build Diary

Fantastic! I always thought Chuck was a brilliant machine. Fast, tough, brilliantly tactical weapon. We had it in one of our rounds at the GSL back in April, I wasn't looking forward to it...

Shame about Project X. The change to LiPo will rocket the performance though! And this time, give it an extra mm of clearance, haha.

Look forward to it mate. I want to see documentation of everything!

Re: Team Microbots Build Diary

Well, the idea was a spinner proof robot...
And it half-worked, the body was written off, but all 6 motors were still going at the end of the day, it just couldn't move because all of the HDPE on the top and bottom was bend up above the wheels . A new 6WD full body hammer is required, smaller, LiPo powered, and lotsa steel! Will be keeping the 40mm HDPE too; it may not be the strongest stuff, but no spinner is going to go through that, the best both 720 & Troublesome did was take about 2-3mm off the side. Add a steel plate onto that and bingo, steel box of inpenetrability .
