Team Coolspeedbot: first feather weight robot

[Coolspeedbot]

Another Pic with the top plate added. weapon motor and mechanism moved forward.



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.

Both of our Featherweight concepts together.

Reminds me of sewer snake.

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

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.

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.

Looks very nice mate, 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!'

You called? Surprised to another person somewhat inspired by Amnesia's mech! Looks very nice, its a bit like a Tormenta 3/Amnesia lovechild.

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.

Refined the design of the parts in 2D.

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.

Well I am considering it but if I choose to work on CSB instead of Wolf-E I'll end up wasting the Drill motors and brushed ESCs as CSB is designed to be brushless. Plus I could do with getting some experience with the weight class first and Wolf-E is a basic machine to get my head round things.

[Coolspeedbot]

Been working on the wedge of CSB's design and reached a head-scratcher. What material should I use on for the wedge so that it can be countersunk so the bolts are flush?

And what would be the best way to achieve the 45 degree angled sides to the wedge? I don't know if it can be done by bending a single part or simply have it in 3 parts and welded them together.



Oh and almost forgot this little render I did for a laugh

I would have thought it would be stronger as a single piece formed into the three angles rather than a three piece wedge.

Well I'm unsure whats the max angle the wedge could be bent before the material (like 4mm hardox) breaks.

[maddox10]

It can be bend 180°, but with the right radius. Hardox will break if bend too sharp.

You can find the working instructions here.

I see, I've had a look but I'm not sure I fully understand how to implement it into the design.
