with 2 weeks to go until the event i intend to go on, now is a great time to get all of the robots i have ready. none of them are in a complete state at the moment unfortunately. so uh… how are they doing then?
Last time Somatic Damage was weighing in a bit too heavy (at around 151-152g), and a bit too long as well in my opinion. so, i set out to change that by making the chassis 1cm shorter and cutting the wheel guards in half which should also half the weight of them (freeing up around 2-3g iirc). but i also wanted to put some wedgelets onto the robot to give it more of an edge in fights. so, with those changes in mind i ordered the prints and when they arrived.
well… there were problems. first of all, the wheel-guards were too big, for some reason i made them a couple of extra mills too tall so they didn’t house the motors at all, something i have since rectified. BUT, they were lighter, and will be even lighter with them being shortened some more.
Unfortunately, i can’t say the same about the chassis. Despite the fact that the chassis was shorter, despite the fact i freed up spaces on the motor mounts internally for the chassis, even despite the fact that i ordered this to be printed at a lower filament than the previous chassis. It was heavier…
(New Chassis (Heavier one))
(Fun lil size comparison)
The old one weighs in at 26.94g. You can decide if that’s good… the new one, or new ones since i ordered 2, weigh in at 28.92g and 32.28g. somehow, defying all odds, the robot has put on weight, and a lot of it. spending today cutting down more weight where i can but mostly hoping and praying. not really sure why 1 print was so much heavier than the other.
but what about the other parts? well, the printed weapon mounts are slightly heavier (less than a gram), but they now offer ground game and also are more maintenance friendly, the top plates (of which there are 4 technically) weigh between the same and about 0.5g less, and the new wedgelets for the sides weigh 0.15 ish grams. not too awful i guess, but i DO need to free up weigh more weight on the chassis to get this bot to a fuller potential.
i got nothing, whoopsie. just need to reprint the mounts to make more space for the brushless motor wires and also re-CAD the beater bar.
The last robot i plan on bringing, which i haven’t spoke a word about on this thread yet, is my first robot i ever got, Manta Ray, who will be filling in as the “Ol’ Reliable” incase my other two bots don’t end up working so well. I haven’t touched Manta Ray in a long time, and at some point the NanoTwo looks to have died inside of it. so i have ordered new electronics for it and i’ll be shoving those in when i get around to doing all the soldering for everything
that’s kind of it for now, i guess i’m looking for advice on a few things so, any help here appreciated:
How much infill do people tend to use for their chassis prints? i know infill isn’t everything However, since i order my prints from Treatstock i can’t really change much about the print. i’m doing 25 for this print but i’m wondering if it’d hurt to go lower to make more weight or not, or if 25 is an ok amount.
how thick do people have the walls on their robot? i do 3mm but i’m not sure at what point it becomes overkill
