ORCHIS FRAME IS RELEASED! Designed for Lancer RPG. Models are test printed at 50 mm. tall size and is provided with pre-supported versions. - Print out the non-supported models at 150 mm. for roughly 50 mm. tall model Get your STL HERE! mmf.io/o/498788
Filling the shelf. None of these stuff are bought. A result of my overly active imagination
I am having a dilemma. I am runing out of my electronic parts to build robots. I want to build a lot more but it seems that I have to cannibalize the old to buid the new I guess I can put the older parts in a project box or something...
The chasis is widened considerably to make room for the spider tank's face and arms. The exibition may be over but my development continues.
Ad hoc guard rail is added to protect the PCB board. It is unlikely that a robot with this kind of COG will tip over but better be safe than sorry. Afterall, visitor of all kinds will be driving it.
I am at a temporary impasse. I have done all I could in my head. Either this thing will have enough traction to move a 1kg robot or it won't. It wouldn't be the first time I made a robot that won't even skid on a flat ground. The only thing left now is to print out and test.
Over the course of desiging parts for my robots I discovered the limit of how small I can make a gear teeth and #3Dprinted it out with repeatable result. And here's the limit. If you are using a FDM printer it won't get smaller than this (unit is in mm.)
Tachikoma (project name) spherical wheel dimensions are dialed in. No gear slip so far. Traction is questionable but that's to be expected from ABS plastic. TPU material could improve it but I will cross that bridge when I get there.
Here's one of my idea that I haven't got around to develop further. Alternate WW2 / Dieselpunk mech suit. So far only 1 design was made then I completely forgot about it. Not sure if people would want something like this.
Here's wild idea I got lying on my bed: 1) Acquire a cheap RC tank 2) Harvest the electronics 3) Put it in my custom chassis A micro controller is overkill for something so simple as driving 2 DC motors. Cheap electronics from a donor toy will be good enough and it comes with a remote control
Maybe unpopular opinion but I believe any job that can be done at home should be allowed to be done at home. Office transit burns massive fuel, building aircon is energy intensive. People could spend more time on leisure or self improvement and spend more money on goods, driving the economy.
Vishwakarma kinetic sculture. The gears behind the God of Craftmanship is motorized. If you told my 18 yr. old self that one day I will be scultpting a God I'd have laughed. I was just rejected by the University of Fine Arts then, on the ground that my drawing sucked.
Very steampunk. I am waiting for a silent clock gearbox to arrive so I can hook it up to a motor.
Replaced all the joints with FDM printed plastic parts. Unfortunately, doing everything with resin is not feasible but at least I can crank out one in 18 hour instead of 48. . It also use only 1 kind of bolt for everything, making the build much more streamlined.
Following the success of the Cataphract robot I will be giving away the STL file for it's caterpillar drive for free. The unit uses a ubiquitous motorized gearbox and the track is print in place. It is good for small robot projects with very little cost. buymeacoffee.com/rattapoomk/e...

When I was recently unemployed, a friend offered me a job to do a jewelry prototype for her. I told her I don't know if I could, sculpting organic stuff is not my expertise. . "I know you could do it", that's what she said. . I came a long way since then
1 day print time for the main Cataphract shell. Well at least I don't have to print a lot of parts. I will cut this piece up to smaller parts but I doubt I will save that mch time.
Standing up using micro servos alone isn't reliable enough so I wrote a code to have the caterpillar drive to assist it the motion. That means it will need some extra code to isolate the transformation from movement. Next time I should use a worm gear but this is good enough.
