Re: Team Ucalegon's ants

Huh, I thought you needed to run servos directly off of the batteries, or the receiver would brown out. (See a page or two up on this thread, in fact). Does the ESC's BEC help in that case? My TinyESCs have them, but I'm not sure what the wiring would look like...

Thanks.

Re: Team Ucalegon's ants

One further question. I have some small, high-powered servos that look like they're close to the "pink" that I use in Swarf, but they're only rated to 6.0V or 7.0V. Is there a converter people typically use to lower voltage from 2S batteries to servos? Preferably one that isn't too big for a 150g ro...

Re: Team Ucalegon's ants

A few videos from a recent competition. There weren't many 150g robots, but I did end up with 1st and 2nd. My vertical spinner has never worked well, but it did great here, for some reason. Swarf v Underscore. "Great fight"--Ray Billings of Tombstone fame actually commented this on Reddit! https://w...

Re: MG90 servos

What do folks typically use to bring the voltage down from a 2s battery for these servos? I presume there’s a standard, lightweight answer that fits in a typical ant?

Re: Antescher Assault Systems build diary

By the way, a while back you lamented the lack of cheap Chinese wheels. I've been using these, and they're fine: https://www.aliexpress.com/item/10pcs-lot-D-hole-Rubber-Wheel-Suitable-for-N20-Motor-D-Shaft-Tire-Car-Robot-DIY/32769037524 And for the orange wheels: https://www.aliexpress.com/item/Smar...

Re: Team Ucalegon's ants

Thanks! It's slowly getting better, as I'm learning from my mistakes: Last year: Match #1: My servo arm was a paper clip, which broke. Cut a polycarb arm to replace it. Match #2: Forgot to actually screw on the servo arm, which broke. Screwed it in. Rumble: Thin taped-on plastic flipper extension he...

Re: Team Ucalegon's ants

Robogames was a blast, and my 150g bot finally won a match. I think Swarf might have been one of the only flippers in the event, in a field full of scary kinetic spinners. Still, I ended up going 2-2, losing to a wide dustpan that I couldn't flip (no 4" cube restrictions here!) and a spinner that br...

Can you wreck an ESC by testing the failsafe?

A friend finally rebuilt his 150g horizontal spinner (Afro 20a OPTO esc, the typical red dys1806 motor), and wanted to test the failsafe. Spun the weapon up to full power, but when he turned off the transmitter, the blade stopped VERY suddenly. He thought maybe it might have produced some back EMF t...

Re: Team Dudge build diaries.

Out of curiousity, how are brushed N20 motors used for hammers? Are there endpoints somehow set so the motor doesn't burn itself out pushing the hammer arm against the frame? Or do you just use the throttle channel and wing it?

I'd love to build something like this, but am not sure how it's done...

Re: Team Ucalegon's ants

Nope, it's a coincidence! The name is from a character in the old, bizzare Uncle series of kids books. The Badfort crowd of villains have wonderful names I'm hoping to use for our bots: Nailrod Hateman, Hitmouse, Jellytussle... Man, I loved Jellyfish, though--as someone whose first bot built not lon...
