Re: Team Shakey Build Diary- Featherweight

How do you plan to join 8mm on edge to the base-plate?

Re: Team Shakey Build Diary- Featherweight

It will probably be a mix of brackets and screws to help support it. My main Concern is if it will flex too much If I am hit on the side so I might add some triangle supports at 90 degrees to the wall. I have worked out that the entire chassis will be made out of 10 bits of HDPE with 5 forming the CAD and the other 5 for the front and top.

I don't look forwards to finding out how it does against axes. I don't intend on putting this against spinners though.

Re: Team Shakey Build Diary- Featherweight

how are you mounting your ram?

Re: Team Shakey Build Diary- Featherweight

how are you mounting your ram?

The ram (When I get aournd to CADing it) will be mounted at the back with a pivot sitting underneath the CO2 tank so it can pivot on a vertical plane. It will be connected by a bar on the front two bars from a mount, which is basically a nut that screws onto the end of the ram welded to another pivot. My only worry is if the bar on the front will withstand the force of the ram or whether it would bend.

Then I have to be careful piping into the ram otherwise it might be caught in the ram which I can't imagine ending well. :P

Also the angle Iron is on order So I can begin building the flipper frame soon so there is something to look at other than CAD.

Re: Team Shakey Build Diary- Featherweight

I got the main shape done and I quite like the look of it. I think it is fairly interesting even if it isn't the most effective. I will be putting some kind of guard around the front wheels at some point.

I'm waiting on some wheels befor eI cad them in so i know the exact details of the dimensions.

Re: Team Shakey Build Diary- Featherweight

Are they 100mm wheels, 'cause there's a model of them on the 3D Warehouse.

Re: Team Shakey Build Diary- Featherweight

That is a bit more interesting than your bog-standard box. It actually reminds me of a cross between Mortis and Vercingetorix/Comengetorix, not that that's a bad thing

Unless you need more specific dimensions, the 100mm Blue wheels are...well...100mm diameter and 30mm wide. Tyre thickness I'd say is probably around the 5mm-7mm mark, then it's the black plastic hub.

Re: Team Shakey Build Diary- Featherweight

Thanks for the info. No more work on the feather as the CAD file is unaccessible right now but I sorted out one of my ants. It needed it after the last event.

A quick C+P from Robotwars 101:
Here is the final version of Stanley Ready for print. It has a servo hold ontop so it can self right/maybe do a bit of lifting/flipping.



And because 8WD wasn't enough I upped the anti to 12WD.


The order has been placed (Along with some wheels for Formic and Flint).

This should address a lot of issues I found at the last event. Somehow the new chassis is lighter than the old one even though this has more things on it. So I used the spare weight to add a selfrighter, bigger wheels and more armour. It is also very wide about 120mm wide but short so it still fits in the cube, this is to make it harder to avoid the scoop and give more controlled turning and to help reduce the likelyhood of spinners catching the side *cough*Combatant*cough*.

Re: Team Shakey Build Diary- Featherweight

Some progress on the featherweight, the design is completed so I am starting to actually build the thing now. I will be making wooden templates for the armour plates so I can cut new ones easily if they get damaged.

Re: Team Shakey Build Diary- Featherweight

that buffer tank looks a bit on the small size for the ram. try and squeeze in a larger bottle or double up.

Re: Team Shakey Build Diary- Featherweight

yeah i would second that, looks small

[Shakey]

Re: Team Shakey Build Diary- Featherweight

You're probaly right. I think there are some 9oz and 12oz around the house somewhere so I will see what room is like when I am done and try to wedge a larger buffer tank in.

Re: Team Shakey Build Diary- Featherweight

good progress tho, whats the dimensions of the base plate?

[Shakey]

Re: Team Shakey Build Diary- Featherweight

The base plate is (including the side bits) 480mm wide and 425mm long. It is on the large side i think but it should still be okay as I can't compact it down without changing the flipper design.

Re: Team Shakey Build Diary- Featherweight

Cut out most the plates and am starting to refine the edges so they fit together nicely.
