Thought I’d revisit one of my bots. To improve its flipper.

Image

I am onto my third iteration of the weapon. Originally I used a fork like flipper. Which was was an awful idea in hindsight, I did it to try and save weight. If it tried to flip a robot the forks just bent and had no power. I added a small support panel on to it which helped a little.

I then used 1mm polycarbonate instead of 1.5mm to make a full panel flipper. Which worked great however a little flimsy. Sometimes not being able to flip 150g very far at all.

So I decided to do some weight saving on the robot to build a 1.5mm thick flipper. Drilled some speed holes, Took off the RX case, chopped some wire and swapped to some lighter wheels.

Jobs left to do:

Trim the carbon fibre rods.
Remove stencil and protective film.
Add acetate to the flipper for better scooping.
Possible paint job

Took me about 1 hour to level the bed as the sensor had not been placed in the right location. 🤯

Looks suspiciously horizontal-spinner :)

Carbide-like ?

Pretty much Carbide/witchdoctor(USA)/Shrapnel(Aussie)

No post unfortunately. I may have to pop down the hack space to make the spinning bar.

Really wish I could make 30th 🤬😕... 13th October will have to be my debut.

My 3 robots are complete, maybe some cosmetic stickers will be added. All made weight and size.



Flip-it, Drax Power and Drax

I’ve put 1000RPM n20 motors in Drax Power....A little too fast?
