Anyhow as said previously more cad to come, possibly today and goodbye!
I have kept the rough layout of the internals, with a bit of movement to allow better access to the switch and lower down drive motors.
I am going to purchase 2mm foam rubber and glue it to the underside of the legs for grip to allow it to stay still while spinning up along with switching to some 100rmp N20s I accidentally bought in order to stay stable on the ground even if it will significantly slow the bot down.
The weapon assembly is at a 10 degree angle, leading to the front end being only 2cm off the ground, allowing it to hit most robots. I have kept the adapter from the original design However if I find it too weak in testing I will have one cut from lasered which will directly bolt onto the motor.
The top plate is going to be cut from 1mm polycarbonate, with 2mm diameter holes for screws.
Anyhow, any advice or criticism is appreciated, and more updates to come.
Apologies for the lack of updates, I have been focusing on my other robot, sir googly, and school recently.
Anyhow enjoy some pictures of the weapon now tightly bolted to the motor, which I finally managed to get to correctly attach to the angled holder. As for the shuffler mechanism, I am currently dealing with some clearance issues but those are easy to deal with
The weapon hub needs to be made around 2mm taller to avoid the ends of the screws holding the weapon to the hub from scraping the polycarbonate top plate I am going to cut.
Speaking of, is it good to cut holes in polycarbonate with a drill, or would that damage it?
Well that’s all, advice or criticism are both appreciated see you all soon!
Edit: the end of the blade will be around 18mm off the ground, the surface it is on is not at all flat
You can drill polycarbonate fine, though sometimes an RC car body reamer gets you a nicer hole. While mostly irrelevant for antweight thicknesses, always worth making sure it’s a smooth hole so kiss it with a countersink or buff it with sandpaper if large enough to stop cracks forming from or through the hole. This isn’t hugely an issue below ~4mm
What will ruin your polycarbonate day is super glue or loctire of any kind getting on it. Basically any glue other than “hot” or a specialist PC glue is a no go. Brittle fracture.
Looking epic! It might be one of the scariest antweights I’ve ever seen! I saw you’re signed up for Orcs so I hope you do some damage!
That’s one mean machine. I can see why it’s used on US antweights, that spinner is enormous, and according to the kinetic energy calculator could run at the rather sluggish pace of around 2/3 of the speed of sound. Tip speed limits are a thing for a reason, I suppose.
This thing is completely bonkers! I think you know you’ve done a great job of a first spinner when the tip speed is faster than a spitfire plane! Can’t wait to see how this thing does when it competes!
