Re: Antweight Database

...8mm ali? Must be an American ant then :P

I might as well list mine here, Jigsaw's glaring at me...

Jigsaw IV
Weight: 150g
Dimensions: 140 x 100 x 63 mm...in theory...it refused to wedge into the cube in Richmond :P
Drive: 2 75.7:1 Sanyo gearmotors run from a 180mah 2 cell 7.4v LiPo and Waller Option D speed controller
Armour: 1.5mm and 0.75mm polycarbonate, 1mm aluminium, acetate
Weapon: HPXF servo powered front hinge flipper/self righter, what Scott refers to as 'awesome cat ears' which are actually self righting assisting devices
Notes: Jigsaws I, II and III were all not especially good and actually followed Asimov's laws of robotics, in that they rejected just about any orders they got and didn't do all that much except randomly twitch until defeat...Spektrum's a wonderful technology, it really is :P
Uses bits from project boxes and video cases
First robot I built that people thought was well engineered, despite me still working on the flipper linkage at 11PM the night before the event
Status: Alive and kicking

Little Yellow Taxi
Weight: 75g-ish
Dimensions: 95 x 73 x 30 mm (excluding aerial)
Drive: 2 SuperTec Naro HP servos, powering homebrew wheels running on a regulated 5v from a 7.4v 2 cell 135mah LiPo
Armour: 0.5mm carbon fibre, 0.75mm polycarbonate
Weapon: E-Flite Park 180 brushless motor powered 50mm long titanium blade/bar/untethered projectile running at ~15,000rpm
Notes: First brushless fleaweight spinner (apparently), has never been all that successful yet still seems to really scare everyone :P and can tear into titanium but strangely not tape?
Status: Being rebuilt, bits are on my desk atm

Re: Antweight Database

Time for my ant

[attachment=0:1m1ylid1]Stack error v2.jpg[/attachment:1m1ylid1]

Name: Stack error
Weight: Currently unknown but about 25g for the main body and 75g of drive, weapon servo etc components leaving 50g for wheels, a hinge , a linkage and the flipper it self.
Dimensions: Roughly 100 x 100 x 45 mm
Drive: 2 x Tower Pro MG90S Servos
Weapon: A HPXF powered flipper. Will be rear hinged if I can find/make a light enough hinge for it otherwise front hinged with the hinged bit of a plastic folder as its hinge.
Armour: The final version will be armoured in 2mm pcb when I can find the etching chemicals to remove the copper. However, I will make a prototype from CD jewel cases (convieniently also 2mm thick) to see If I can cut it by hand easily or if I'll need to borrow a laser.

Re: Antweight Database

Robot: #1
speed: super slow
Power: 4.2V 300MAh NiMh
Drive: Cheap servos
Controller:
Weapon: none
Armour: 2mm card
Status: Active
Photo: none

Re: Antweight Database

A few updates since last time :P

Jigsaw V mk. II
Weight: 150g
Dimensions: 135 x 100 x 40 mm
Drive: 2 x 50:1 Pololu HP 12mm gearmotors driving 32mm rubber tyred wheels, run from a Peter Waller option D speed controller and a 120mah 7.4v 2 cell lithium polymer battery pack
Armour: 1mm polycarbonate chassis, 0.9mm titanium, acetate
Weapons: Front hinged flipper/self righter powered by a modified 4 bar linkage from a Hitec HS82-MG servo run from full battery voltage
Notes: Was initially built for AWS32, but after numerous issues had a new chassis built after the weapon system more or less imploded at the event. Uses bits from video cases, Velcro tape, and random other components
Status: Alive and waiting to fight

Pictures can be found at http://s267.photobucket.com/albums/ii30 ... d%20diary/ for those that are interested, with commentary by myself for those insomniacs among us whom medical science has failed.

The Data Fields
Weight: 120g
Dimensions: 170 x 100 x 25 mm
Drive: 2 x 50:1 Inertia Labs 12mm gearmotors driving Tamiya track drive sprockets, run from a Sozbots SOZDSC-M speed controller and verious 2 and 3 cell 7.4/11.1v lithium polymer battery packs
Armour: 1mm hardened aluminium chassis, 1mm polycarbonate
Weapons: Interchangable rambot - options include hardened steel dart spikes, various scoops, shields, bumpers, whatever I can fit on really
Notes: On its third or fourth version (minor changes in between each, mainly to the armour, radio reciever, weapon setup, etc.) and perennially underweight despite relatively heavy components and home made axle blocks (!)

Arcus
Under construction antweight with claws, currently waiting for me to work out how to armour such an oddly shaped thing :P

Re: Antweight Database

Tracked robots FTW!

[joey_picus]

Re: Antweight Database

Arcus is done...well, it has been done for a while actually :P but only just got around to posting it, so here we go. Shane called it 'nuts' at Kidderminster which I can only assume is a good thing, heh...

Arcus
Weight: 125g
Dimensions: 145 x 120 x 25 mm
Drive: 2 x 75.7:1 Sanyo gearmotors (out of Jigsaw IV) driving 20mm diameter rubber/Dycem tyred wheels, run from a Peter Waller Option A speed controller, 135mah 2 cell 7.4v lithium polymer pack, and a spaghetti bolognese wiring setup
Armour: 1mm hardened aluminium chassis/base, 1mm polycarbonate rear armour, 0.5mm carbon fibre top panel
Weapons: Aluminium claws (obtained second hand from Dave Weston, I believe they were originally made by Tony Fowler) driven through servo gears and a Futaba S3102 metal gear mini servo
Notes: Self righting is through a consolidated synergetic multi-party platform system designed to overcome shortcomings in the individual (i.e. it's nonexistent and relies on the other robot to flip it back over). Not really a competitive antweight - it doesn't quite fit the 4 cube with the claws in any position - but it works well for demonstrations and is unbelievably fun

Re: Antweight Database

Looks very pretty

Re: Antweight Database

Did you ever find out the cause of the burning incident at RFRC Joey?

[joey_picus]

Re: Antweight Database

I think the servo just overloaded, they don't really like 7.4v that much...the circuit and motor had both gone, I actually blew another servo at Kidderminster (thankfully just the motor, there was no smoke this time) and I find myself having to avoid heavy flipper usage in order to avoid burning them out...it's a strange situation, I may need to revise the linkage as far too much pressure seems to be borne by the servo when it self rights, that or look for a different servo.

Thanks for the comment Connor

Re: Antweight Database

Arcus Looks great joey :P

Just a few questions

Is it invertable?. Cos that might be a problem facing bots like Void and Anticide etc

and also it weighs 125g. Could you possibly switch the armour to titanium?

[joey_picus]

Re: Antweight Database

Thanks for the compliment it's not invertible as the linkage gets in the way, I keep toying with ideas for a srimech though.

As far as armour goes, titanium costs over £20 a sheet and takes absolutely ages to cut and bend with a Dremel and vice, and the polycarb and carbon fibre protects it from what it faces well enough...so nope, not considered switching the armour :P

Re: Antweight Database

Thanks for the reply Joey

You could make it a rollcage, but that might be a bit difficult
