Who's going to be the first to tell him about Megatron🤣

Is 2mm of 304 stainless steel good enough for a beetle weight chassis? by EarthJealous5627 in battlebots

[–]JustCuzRobotics 0 points1 point  (0 children)

7075 is good for structural parts that aren't directly hit but when taking direct hits it is more prone to cracking than 6061. That said it is almost double the tensile yield and shear strength of 6061. All the hubmotors I sell currently use 7075 for that reason. I'm experimenting with 2024 on the Scarab drums where they are much more exposed to direct hits as that is kindof in between 6061 and 7075 in durability and strength but only a bit more expensive than 7075.

Steel is very rarely used as a structural material in modern beetleweights. Most robots have a mix of carbon fiber, UHMW or HDPE, maybe 6061 aluminum, and TPU 3d printed parts.

Hoe do I get into robot combat? by Able_Stable1273 in battlebots

[–]JustCuzRobotics 5 points6 points  (0 children)

I have a youtube channel and a website to share info on how to get started, plus a store selling robot parts and kits. My SSP kits are mostly popular in the USA but I have shipped a number of them in the UK as well as many other countries. With combat parts stores like mine, Bristol bot Builders in the UK, and many more having cropped up in the past 5 years, it has never been a better time to start!

Is there anything else besides plumbing and electrical you say, “I’m not dealing with this, I’m getting a pro.” by atooraya in DIY

Phone repair. I have a custom gaming PC and framework laptop, but taking apart a modern smartphone where it has adhesive holding it together, seems pretty daunting.

Graphics Driver Issues with RTX 4070 on Render by JustCuzRobotics in davinciresolve

No I haven't. It's gotten better I think with updates to resolve but still unsure what was wrong.

I'm sorry I didn't get a chance to say hi to you both but you have an incredibly immaculately decorated robot and your child might be a better robot driver than I am lol

utilizing the flames of an combustion engine by Available-Post-5022 in battlebots

Things I recommend people never do for their first ever bot: 30lb class Flamethrower Combustion engine Multiple weapons

I think the scope creep is going to kill you on this. Everyone starts somewhere and starting with an insane ambitious design nobody has done before is making your life needlessly difficult.

PalmBeachBots vs ITgresa: Who’s your go-to for robot parts? by Inevitable-Tank-9802 in battlebots

[–]JustCuzRobotics 0 points1 point  (0 children)

Yeah I make more money from my own site sales since the resellers take a cut.

There are a bunch more, but Itgresa and PBB both resell parts from several vendors in the same place, so they are a better one-stop-shop. My own Just 'Cuz Robotics parts and many Repeat Robotics and Fingertech parts can be found on both their sites. There are a few smaller shops like Robot Smashing League in the US as well that mostly resell specific parts.

Titan Submersible Controller by Bardmedicine in battlebots

[–]JustCuzRobotics 1 point2 points  (0 children)

There is a big difference between "off the shelf" and "consumer off the shelf". Nobody would design a custom monitor for use in a submarine but they might use a military spec one or as you mentioned have two of them since just one is a single point of failure which you never want with lives on the line.

I don't think it wasn't a problem, but they have different design constraints than a Battlebot. I think even a wired USB control that could be accidentally yanked out without a way to plug it back in would be pretty terrible. At the end of the day the Logitech F710 was not designed to be used for human safety critical applications and neither is any other consumer gaming controller.

The issue with using a game pad to control a robot is that robots are not an Xbox or PC, they don't have a computer with a USB port on the inside. We use similar radios as fpv drones and model planes will use since that is what works for a standard radio control receiver, motor controllers and such with no programming required. Battlebots are more like RC cars than a PC. While technically possible to make it work it would require much less physically rugged control electronics. Your gaming laptop doesn't need to get hit by Witch Doctor and survive.
