Putting a solid shaft in takes almost no time at all, taking weight out to compensate for the heavier drum shaft is the tricky bit, especially as Reboot is getting a set of cp2400ís to replace the old drill packs.

The cp2400ís are heavier. Sad

Guaranteed to ReBoot your bot again..and again..

Back to 13.6kg, legal with its heaviest drum and battery pack now with a solid shaft I'm much more confident with. Just needs final assembly and its ready to rumble. Wink

Robs off visiting his Mother so no Internet access for him.

As far as Reboot goes very low maintenance event. We didnít even change the battery pack having plenty of time to charge. One advantage of staying on the winnerís side.

Only thing we did was swap Benders radio into Reboot and disconnect the flip after some gittering in the Eleanor fight, not sure what was going on so we decided to be cautious.


Main thing to think about is the tendency for Reboot to flip when hitting an immovable object, thatís what bought him undone in the Brisbane Singularity fight and almost ended his run at Sidetracked.

Technically a flip of an invertible bot rates as trivial damage but it looks bad. Reboot actually suffered more damage at the practice day the weekend before when Bane hit him.


The big upgrade for the event was good quality belts, Reboot has lost fights due to snapped or striped drive belts in past events so that was one less thing to be fussing over, probably run higher voltage now if we wonted.

The other change was an experimental aluminium drum axel but didnít fight anything that would have really stressed the drum, King Cobra was the hardest on the drum.

Yes I really would have liked to verse reboot also. Smile You must come down to the annialator!
Just wondering, I was having a bit of a sticky beak at it, it runs at 30v right? And I noticed the weapon scooter motor's case has been lathed down! Shocked I thought that was somewhat interesting... Smile

24 cp2400cells so whatever you wont to call that,

We were struggling to save weight you might have noticed holes in everything so we put the yoke in the lath and cut some material from the area around the brushes, we didnít wont to reduce the field flux by thinning it down where the magnets work.

Thanks for the comments.

I think Reboot has a good balance of speed maneuverability hitting power, defensive moves reliability and with Robs driving it has a good chance against most of the other bots in the comp.

We will build a new one when the time comes, been thinking of different wheels and a chain drive but I donít think they would work a lot better and they would be heavier.

Hope we can get to the Annihilator this year we will certainly make it a high priority.

I might try a chain drive 100-watt combo in the next version of Bane.

Getting closer to a design for a new feather weight drum bot.

Probably going to call it Minimower Mk 2 as itís a lot more like Minimower than Reboot.

Wide drum and straight wedge.

Lower, tougher, less likely to flip on impact.

Boring boxy shape, cant have everything. Smile


Twisted Evil Thought the NSW crew might enjoy another visit from Minimower to.

Shocked No.... Reconsider it Gary, don't build a boring box spinner!!! Reboot is like one of the only few non-boring box spinners out there, it's shape gives it style and character...

We donít intend to retire Reboot; hopefully Daniel might take him to Robogames.

As far as a new Reboot we havenít come up with any worthwhile improvements to justify a rebuild.

If Reboot comes home in a bin bag we will build a new one.

Minimower is currently still active and mixed it with the current bots in the second day rumble. Smile

There is a lot of room for improvement with Minimower but Rob wants to keep the original as is so a new one is the way to go. Cool



Got to remember NSW is hard-core battling, no crowd to please there, think they dropped the style point from there judging to. Smile
You donít take a knife to a gunfight.

Well, Reboot is patched up and running again after the Jolt fight.

Substituted a drum, drum axel and 100watt scooter motor that drives the drum.

Was going to modify him to take a larger diameter drum axel but no time.

Problem is the drum axel bends then the teeth of the drum hit the weapon motor; things go down hill from there.

Have dug out Reboot, totally dismantled and partially cut to peaces and a pile of parts accumulated some years ago that were intended for a rebuild/ upgrade.

Thinking passably freshen up the original and try and build a new one at the same time.
Easier to fine tune new one with old in pieces to compare.

Reboot Old a few years ago

[/URL]

4 july 2016
Old reboots on the bench receiving upgrades. Gary will build this one first with new ideas as a trial before starting the frame on Reboot II. Few new things are we have a chain to the friction wheel on the drum. The drum axel is a solid high quality piece of aluminium, the legs at the front are a stronger piece of tube. The motors are now 12 volt at 100w instead of 24w 100w scooter motors.



6 july 2016
New reboot pile of parts on bench as you can see a couple of weeks ago and reboot II was a pile of parts. Was thinking about using a tube frame like the original but went for a square hollow section. Much easier and by the time the bumper side armor is on the robot looks like the original anyway.





Drum end surfacing drilling holes. This forced us to fix the vice which had been broken by the old owner. Gaining a fair bit of skill on the mill now.



9 july 2016
Started drum drum getting countersunk drilled and tapped


10 july 2016
Old reboots Back together
Reboot back together


12 july 2016

Frame taking shape motors are in. Little more weight to use to mount the motors these days. Thats strong steel, another automotive initiative, part of a tail shaft.
july 2016 frame taking shape



much beefier legs, single section pipe. good quality steel.


much bigger drum axle, considering we started with towel rail over 10 years ago.


new drive motor mount in tailshaft steel section and new clamps


friction drive need reinvention due to the frame being a bit short. necessity is the father of invention.


needs a bit of armor at the bottom but see what weight is like after wiring


4 july 2016
End caps fitted bearings smoothed sides in lathe bored out hole. 6060 t5 aluminium. had the stock for many years with this purpose in mind. bearings are protected by rubber housings. intended for use in large fans.






15 july 2016




18 july 2016
Finish drum weight on scales


17 july 2016
Construction basically complete




21 july 2016
Wiring reboot

If you can afford to feed it Argon, with a decent size bottle of argon gas, then you can grab one of the small inverter Arc welders and a scratch-start TIG add on kit for it for under $200

or for under $400, you can get a Hi-Freq start, Arc, Tig and Plasma Cutter (DC Only) that does steel and stainless steel - http://www.ebay.com.au/itm/ROSSI-CT416-Welder-Inverter-TIG-MMA-ARC-Plasma-Cutter-Welding-Machine-Portable-/130836607781?hash=item1e76783325:g:5wUAAOSw7XZXhCAq - Thats what I run at the moment.

If you want to be able to do Aluminium (which is a lot harder), then the machines start to get expensive. $1k+

Thats quite a build report there Rob. Nice Photography ! Smile
