Team Coolspeedbot: first feather weight robot

[Theo]

I think you should do this instead of Wolf-E. All you need is a beefy motor and gearbox with an accompanying ESC and you have yourself a, by the looks of it, much better looking machine. Or you could still do Wolf-E if you have reliability in mind.

[Coolspeedbot]

Refined the design of the parts in 2D.

You called? Surprised to another person somewhat inspired by Amnesia's mech! Looks very nice, its a bit like a Tormenta 3/Amnesia lovechild. A bushing went missing for the spur gear during my fight with Beauty and Conker so the gears weren't quite aligned anymore but, it managed to keep working without slipping up to the 3rd/4th playoff so it's a very reliable linkage if you use the right mod gears.
Best of luck anyway and looking forward to seeing the finished machine 'do the thing!'

Thanks Adam, considering both Tormenta 3 and Amnesia are the main inspiration and frame of reference on what has be done before, it's fair to call CSB their lovechild.

More internal designing, featuring rough renditions of brushless motors with gearboxes and trying out a mechanism based on what I have seen being used in another featherweight front hinged flipper called Amnesia.

A top down view of the tight fit for the motors, plus the battery has a it's foam and holder. Adjusted the wheels slightly.

Reminds me of sewer snake.

Kinda see that you mean, except sewer snake's wedge lifts up where as mine doesn't.

Both of our Featherweight concepts together.

Thought process behind the design:

The robot as loosely mentioned before will use (hopefully) Brushless motors for drive and weapon using Saturn-16 like gearboxes with the weapon running on a higher gear ratio (64:1) before running a 2:1 ratio gearing for the final stage of the weapon mechanism. As for the drive I'd most likely use a standard gearbox, running the middle wheels directly off the gearbox while the front and rear wheels are run by drive belts. They may need the use of 3D printed wheel hubs with pulleys built in.

As for the materials, most likely some Hardox but the wedge might need to be made of a material that can have bolt holes countersunk so it is flush to wedge bots smoothly.

That looks very cool, man. Nice and compact as well. I didn't realise you were designing a front-hinger too. If you build this we will need to have a battle!

Thanks Dominic, it's that compact that it's roughly the same size as your FHF bot concept. And yeah we need a FW FHF match. Though I need to actually build Wolf-E first, then again might not hurt to build this instead.

So I've looked at down sizing my 6WD bot codenamed CSB. I've also considered using brushless motors, gearboxes, drive belts to run the drive.

Added link covers, made mounts for XT60 connectors. Narrowed the 6WD (currently 48cm x 46cm x 10cm ) bot and arrange most of the mock internals.

More work on my 6WD bot idea.
