Team DD Robots

[gizz]

Hi!

Starting this thread to have one place where I gather all my projects.
I'm a swedish roboteer whos been around for several years but yet to actually complete
a worthy combat robot!
I wont post pictures of my old projects but they can be found on my photobucket page.

My FW is on it's second version as the first one was a trial and error one, it did actually work decent!

My ant is being completely rebuilt for the 5th time as there have always been things I havn't been
satisfied with.
The current name is V5 which stands for Version 5 and now I'm keeping things simple and here's the result so far:


6V Voltage regulator for weapon servo along with a removable link made out of a jumper.

Specs:

1mm Polycarbonate
Polulu 50:1 HP motors + wheels
Sabertooth 2x5RC
OrangeRX dsm2 4 chan reciever
Gravity 250mAh 2S LiPo
GWS Park HPX Flipper servo

Re: Team DD Robots

looks good why do you need a voltage reg?

Re: Team DD Robots

Cheers, well i dont think my servo would handle the 8,4V from the Lipo pack and not sure if the BEC from the speedo will manage
to power it either.

Re: Team DD Robots

Actually the HPXF's will run on lipo voltage, I have done in the past. Put the positive line from the servo into the positive terminal of the speedo to use it on full voltage. I would recommend to avoid stalling it at all costs.

Re: Team DD Robots

You underestimate sabertooths, I have run lots of setups using servos off the saber BEC and it works just fine.

Re: Team DD Robots

Ah I see thanks for the info.
Just remember I've read about ppl having the bec to shut down while using the Park HPX servos because of their high current draw
and wanted to not suffer from that, and afaik it would be able to flip most things at 6V anyways.
But I'll look it up and try it in another project as I should have plenty of weight left over for the regulator anyways.

Made the top shell along with servo holder and then soldered the regulator to the removable link and put a mini deans as the cables were short:


This is my current progress on my FW which has no name as of now:


Specs:
4WD by 4 standard drill motors (100mm blue wheels)
Sabertooth 2x25 Speed controller
Lifter powered by drill motor and threaded rod
Electronize 30A weapon controller
4600mAh home made NiMh 12v battery
15mm HDPE armor (5mm top and bottom)

Re: Team DD Robots

I've now finished the top and sides of the robot, including soem side rails so it wont get stuck.
Flipper arm is also done and the last part to be done is the flipper scoop itself out of 1mm titanium grade 2.

Re: Team DD Robots

I am building an ant with all the same parts funny enough, what weight are you at now then ?

[gizz]

Re: Team DD Robots

Ah sounds nice
Havn't rly weighed it until now but the scale show 148g, without the ti flipper blade..
I'm gonna reduce the size of it, and started to plan where to get rid of some excess weight.
Gonna try to see how much 1mm titanium weigh, but it should be alright.

Re: Team DD Robots

Actually ordered some 0.4mm titanium aswell to possibly replace it later on to get a bigger flipper

[gizz]

Re: Team DD Robots

Flipper is done, but waiting for the new sabertooth and then strip the plastic off and I will post a pic and a test drive vid.

Meantime I started building the tracked ant, quite basic and unfortunately gonna look much like other people's tracked ones.
But I want one so here i go

Specifications,
Drive: 2 Pololu 50:1 HP motors
ESC: Sabertooth dual 5a
Tracks: Tamia model tracks + extra grippy material
Battery: 2S 240mAh Lipo
Reciever: OrangeRX 4 chan Dsm2
Armor: 1mm Polycarbonate
Weapon: 0,4mm Titanium grade 2 wedge (or 1mm if I got enough weight)

Re: Team DD Robots

My flipper is done and now named Bounce!
It has been some planning and then much trial and error but the general idea was having a flipper with low ground clearance,
non-exposed wheels and armor all around and this is the result of my first combat ready ant I'm actually keeping as it is for now.

Specifications:
Motors: 2 polulo 50:1 HP
Esc: EScheap10 from botbitz
Reciever: OrangeRX 6 chan DSM2
Battery: Gravity 250mAh 8,4V LiPo
Weapon: Park HPX BB servo operating 0,4mm Ti flipper
Weight: 145g





Recordded a 1 min long vid of test driving, its about 100mb, do you know of any good program I can use to shrink it?
And maybe add some text as description?

[harry hills]

Re: Team DD Robots

add text in movie maker and upload to youtube?

Re: Team DD Robots

how sthe featherweight coming on?

[gizz]

Re: Team DD Robots

I havn't actually done anything on the feather for months and thus its in the same shape as in the picture.
Have worked out more on the design and the use of limit switches etc so once I get to it again it will go quite fast
as I got all the parts really.
It's a bit cold atm in my brothers shed but I'll try and get some heat fan going and it should be ok working out there again!
