The video demonstrates the build process of the Robak version v2.0. We now have an upgraded v2.2 available. While much of the process remains the same, you'll notice some changes in the parts during the assembly of this latest version. To guide you through these updates, I've created an interactive document detailing the design changes and offering additional tips. Link in the description.

Thanks! I couldn't find anything about anti duck and dive, is it related to the steering geometry? :) Bump steer is noticeable, I didn't know before what such an effect is called, maybe I can somehow fix it. Ackerman angle is already implemented. Caster and camber is set to neutral by design - probably not optimal but maybe as you said I should spend some time to find a better setup. So much to do and so little time :D

That unsupported chassis that's just a 2 wobbly bits of flat plastic 😱

@robaki-dev

Absolutely, a little give in the material helps with taking hits without breaking. With larger printers, we can get the chassis as one piece, which increases the sturdiness without sacrificing the flex where it's needed.

lay a spare tire over the wingnuts on the top

very very nice to see creativity. I'm a big fan of model cars. Think you did great here, was an enjoyable video to watch. Steering geometry looks great, chassis in two halves, I think will separate by themselves if you don't add more bracing! Are those FTX differentials? I use them a lot! Was laughing to myself when I saw the motor position - you printed a new top brace to avoid the wires..I too know the pain of clearance, but I'd have spin the motor round not made a big gap for the wires. All the same, a better, braver, bolder build than I have made myself, so please take that as a compliment 👍🍺🇬🇧

Hi, just watched one of your video to see what FTX is 😃. Great content BTW I'll come back for more :) For Robak I'm using HSP parts - diff name is HSP 02024. And yes... there must be a weakest link somewhere 😃If it breaks I'll upgrade it like I've done with the other parts. This process never ends. Regarding that top brace cutout I have now doubted. Was almost sure I tried rotating the motor and the wires didn't fit under the body. On the other hand I'm not seeing many people using this cutout as I do. I'll check it once again. Thanks! 🍺

Hi, I was looking at trying to design an RC car aswell although I'm very new to this. Did you buy the parts and measure them before designing around them or did you just work off of online datasheets. For example, I was looking at the HSP drive shaft and I could not find the radii for where it connects to the wheel at 2:30 in the vid, the Aliexpress page for them likewise has no information on it except stating it was suitable for 1/10 size RC cars, I'm not sure if there is a standard size. Would appreciate your help and love your video.

Kits are available from @rcprinter, who prepares them based on the original BOM for various 3D printed RC vehicles. Printed parts are not available for purchase, as owning a 3D printer is highly recommended. The main advantage of this project is the ability to reprint parts at home, so you don't need to buy new ones when they break. I gave one of the cars to a young relative who doesn't have a 3D printer. No worries though, I've got them covered with a lifetime of help with the parts they need. 😄 I recently experimented with a BeagleBoneBlue SBC with Ardupilot and GPS installed and the waypoint navigation worked wonderfully. However, I've temporarily removed it due to the snowy conditions here, as I'm concerned about the electronics 😀. On the Discord channel, I've noticed some attempts at integrating FPV cameras, which is quite interesting. Additionally, there's a reduction gearbox modification available on Printables that I'm eager to test soon to enhance climbing capabilities. I'm really fond of the Robak community and its innovative spirit. ☺️

Thanks! Most parts are from PCTG which I use interchangeably with PETG and PLA+.

Full list of parts and materials is here github.com/robaki-dev/robak/blob/main/3DPartsList.csv

How reliable is it? Where are the weak point I should expect? And how much overall does it cost for the parts? Awesome built btw!

@robaki-dev

Жыл бұрын

Thanks! It’s reliable until you crash it, which is very likely to happen. Sometimes printed parts break while bashing so it’s recommended to have a 3D printer at home to fix it quickly. The most common part that breaks is shock tower and steering blocks. It would be great if those are printed in nylon or similar. The durability of the metal drive components is impacted by the quality of the assembly and 3D printer accuracy. Gear mesh, clereances etc. It’s hard to get it right at the first time but the Robak is a more of a project to develop and repair than make it and forget it😉

As the carrier hubs go inside the rim the minimum rim inner diameter is around 2.5" - determined by the height of carrier hubs. With such big wheels there is no room to make the wheel track narrower unfortunately :( I know that some truck bodies will fit after minor modifications.

@robaki-dev

Crashes are inevitable when you push the speed, and yep, parts will break. But, if the car is built correctly, with 3D printed parts that match the design tolerances, using the right settings and materials, it can absolutely handle jumps. It's all about finding the right balance between being strong and not too heavy, so it's tough where it needs to be without breaking the bank on metal drivetrain parts. Every build is unique. Some folks get better results than others. There's always room for improvement, and most of us keep tweaking our builds to make them as good as they can be. It's a process of iteration, finding what works best for your specific needs and driving style.
