Robot name : Eleanor
Team name : Team Ellis
Location: Sunshinecoast, QLD
Robot weight(Class): Feather weight
Type of Robot: Wedge/Rammer
Drive system: Team Delta Dewalt setups

Power: A123

General comments: Wedge/Rammer one end wedge and the other for ramming. Pneumatic self-righter.
Unusual characteristics: I wanted to build something I hadn't seen before. The pneumatic self-righter fires into the ground, not using any arms or leavers. It also has a power LED in the ram tip for display.
This is my first combat robot I will be competing with and plan to have it completed in about 4 weeks. _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Two thumbs up and a gold star to Team Delta. After placing an order with them weeks ago the dewalt motors were out of stock(thanx Nick ). After being patient, they arrived in stock. Dan halved the shipping cost and sent them out Friday....they arrived today! Thanx again guys.
I hoping the power of the Dewalts should make a dull wedge more exciting and fun _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

A little bit more cad work done...Both bearing blocks have changed. The large ones will have rubber between it and the shell and will be the limit of travel from shock loads. The small blocks will be made from ali and are small in size too create clearance for shell mounts. Height adjustable shock mounting from shell to base plate has also been sorted.
Ooooh This "boring" wedge is stating to look quite interesting there young Trent. Do you think you could incorporate some adjustible ground clearance into the bot, something you could adjust and fine tune before a battle to ensure you don't beach yourself on the arena floor like soo many other wedges. _________________ https://www.halfdonethings.com/

About 10mm of adjustment....Also the front and rear skid pads(not Cadded yet) will be adjustable from nil to whatever needed. _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

I was thinking if you made a hinge for the base plate to attach to the shell with, you could just undo the two bolts at the back and just open the bot up like a brief case and work on it
Going with the adjustible caster idea we discussed? Or another idea? 10mm GC is fairly normal, but maybe you might want to just make it so you have it optional up to 20mm. I had 10mm GC on Annihilation and lost a meele because I got beached on some strapnel

Wedge for simplicity, its my first combat robot!
Thanx for tips and ideas, it all helps. Its a new adjuster and I'll put some pics up later to show, it also could have infinite length adjustment easily.
Brief case hinge idea would would remove shock mounting unless you shock mounted the whole hinge. @ the moment all I need do is remove four hairpin cotter-pins and the base separates from the shell, not only will it be easy to work on but it would be drivable too
Yay, now I'm still waiting for timing pulleys . Don't ask about them grrr.
I'm off to cutout the shell mounts now, with the grinder..... _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

You are going very well, Trent. I'm up to about my tenth bot and they still look like crap. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

Mounts are done, within 0.25 of mm again. Those 1mm cutting disks are great, thanx for the tip Glen!
I'll will make a jig for welding them to the shell tomorrow, and maybe even weld them as well.
Thanx Phil, I reckon your new bot looks like a cross between Marauder and Hellcat. So I'm guessing you can't go wrong! _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

hahah spiffy.
is there a weld nut or something welded into the tabs? looks like you need to get a spanner into the body to do it up in the cad lol
cant help but think it would be better to shave off all the excess base plate and make flanges on those inner vertical parts to bolt the shell onto. those tabs look awefully cantilevered and flimsy. the ones i had on kang holding the base on snapped off as soon as someone hit the thing (it was aluminium but none the less heh).
can you jack the back of the chassis up and down the adjust the clearance?
