That's a lot to cover in a RUclips comment lol. There are tons of ways to design a robot of course that's why they all look different. A pretty common archetype these days is using carbon fiber or aluminum base plate and top plate, UHMW frame rails that hold the shaft for the weapon as well as have the structure for the main body, and 3d printed TPU for most everything else.
There are lots of options for electronics. Repeat Minis are popular for drive motors and I sell an RDY-5022-MINI hubmotor weapon motor that's perfect for antweights and has been used by several beetles for hammersaws too. AM32 35A brushless ESC I sell pairs well with the Hub-motor and a malenki HV is a cool receiver and brushed drive ESC combo
I own an X1C with the AMS and a P1S. Both fantastic. However the AMS isn't that useful for combat robotics. It can't keep filaments like nylon dry and its not compatible with abrasive fiber filled materials or with TPU which is probably the most widely used by far for combat robots
I gotta ask, what is the purpose of putting your robot fully in CAD (wheels, motors etc)? Does it make printing easier? How do you make the individual parts like motors and wheels in Fusion 360? Thank you
It helps get an idea of the robot and lets you model around parts such as leaving wheel wells or mounting points for motors. Grabcad is a good place to look for cad files of parts
Firstly its a requirement to 3d print parts. Secondly making sure all parts exist in a 3d model makes it so you know for a fact you can put it together in real life and have room for all components. And getting anything manufactured be it laser cut or CNC machined pretty much requires a 2d or 3d cad file
Often you can download models for parts and I have models for most everything I sell available on my website as do most manufacturers of combat robot parts.
Huh kinda surprised you haven't mentioned chains or gear drives as they can also be used to transfer torque to run a spinner along with belts. Anyway good video all the same.
That's fair although I said at the start I was trying to make a 15 minute video and it's actually 23 minutes lol. I couldn't cover everything in detail without the video getting super long, and probably 99% of spinner combat robots in the 3lb class and under use a belt driven weapon or direct driven/hubmotor style so that's what I focused on.
Not sure what the benefit would be of a full video for that. The exact same rules apply as timing belts but you use sprockets instead of timing pulleys and chains can be broken and rejoined so you can design a little different than for belts. But I think the fact they will snap too easily from shock loads makes them unsuitable for pretty much all combat robots under maybe 30lbs. At 30lb and over, they still are not good to use on weapons that often experience shock but can be useful on drive due to being relatively narrower vs a similar belt drive.

Spin to win
Nicely done
I love your tech videos! Looking forward to this one.
Another great video. I really like you hub motors too and would love to try one on a beetle hammersaw
Comgratilation for Tutorial... Great 👏
Fantastic video.
Thank you!
How would you design the frame to house the drive motors and all the electrical components for the vertical spinner?

What would you recommend for a 1 pound ant weight insides such as motors and boards for using I don’t know much about electronics. Thanks

Would you say the Bambu p1s with the multi color printing attachment would be a good printer for this

What would you recommend then
@Firstordertrooper P1S without multiple material system is still awesome

I did mention gear drive. Chains do not offer many of the same benefits as belts and tend to be way heavier and impractical for robots under 12lbs
Sorry was expecting a tad more detail like you did with belts.

@@JustCuzRobotics OK fair enough but would be cool to see you go into a bit more detail on chains tho, maybe like a part 2 to this video perhaps.
Not sure what the benefit would be of a full video for that.
