Hi Robot Geek people

First time i saw Chip-E was really proud to see more small bipeds are coming out as a result of an iterative process in the world opensource robots. Then i read the Make magazine amazing and thanks for mention Otto as part of the inspiration, thanks for that.

I see you are using CC-BY-SA and that is great, but we have to admit to the maker world that Zowi, Otto, Tito and Chip-E are all remix and inspiration from Bob; i suggest you to give them credit and put it as a remix for Thingiverse too.

I really Like the contest you did, looking forward for some future open collaboration.

Best Regards
Camilo

If anyone is having trouble getting the Arduino code to compile, you'll need to install the RobotGeek libraries from here:

if I were to add arms, where would they go?

Are these files in millimeters or in inches?

Millimeters! Sorry, should have made note of that, it's important!

Hey Robotgeek! I would like to take part in the contest and have a few ideas of my own. Naturally I would like to start modeling but I need to know 3 things, I noticed your servos are locked 180 degrees, can I still take part if I remove that restriction? Also is there anywhere I can get a 3D model of your "RobotGeek Geekduino"? lastly what are my restrictions, does it need to by humanoid or a similar to what you made? I have some ideas but they are more machines involving your kit in them, would they count as well?

Thank you!
-Yuval Dascalu

On Servos: Feel free to add parts as you see fit including but not limited to continuous turn servos (we do offer those in the same housing as the 180 servos).

On Geekduino model: The Geekduino has the same mounting points as an Arduino UNO, and we do not currently have an accurate 3D model of it.

On Restrictions: If you feel inspired to use the parts in the Chip-E Kit toward another style of robot or machine, feel free to throw it in the competition, we'd love to see it! As much as we would like for people to modify Chip-E as a walking/dancing/goofin robot, we're well aware that the RobotGeek parts included in the kit are quite versatile and could be configured into entirely different machines.

One more question, how about trade-marketed character, like from a movie? And just because I can how about wooden boards or bearing? silicon bands?

We'd prefer original characters, but some people have used trademarked characters, so as long as you're comfortable with riding in the gray areas of fair-use, do what you will.

As far as the other parts mentioned, as long as you keep in mind that this is a contest on thingiverse, which necessitates at least some 3d printed parts, and include a source for where someone else trying to build it can find the parts you used, that would be fine.

Y_Dascalu - in reply to robotgeek

Hey, I tried to follow your guide lines as to what counts for the contest, after a week or two I have my entry and just wanted to make sure it still counts as an adversary. https://www.thingiverse.com/thing:2426406
Notice I did do my best for it to be a remix, using parts and/or parts of parts in the finished product, and staying loyal tot he kit.

Have a nice day!

Helping Hands Operator - Automatic Soldering Tool by Yuval Dascalu

It looks awesome, and it's well documented! We love it!

And I love you back ^^

:3 <3 <3 <3

Sorry for the servo price is very high. It was possible to use a conventional servo. It looks like a marketing move.

By conventional servo, did you mean the pwm servos you can find at hobby King? Because I'm looking at the stall torque on them and cheapest servo I could find at hobby king that similar torque values is over 70 freakin' $ a pop. These are almost strong as robotis ax-12s and those cost like 50$ each. Can you point me to a servo that's less than 20 bucks that has a stall torque around or better than 12 kg·cm? I'm trying to understand how you figure this isn't worth it and I can't find real world examples that back it up. Good shit costs money not everything can be dirt cheap like 9G servos. I didn't yell at this one for being dumb you happy robotgeek? You fuckers need to make a video or something showing off what a high torque servo can do so these people stop getting so completely buttharmed over nothing. this is stupid I shouldn't have to tell a company to pimp their own shit come on.

Sir, the question of dolphin_max is very valid. In my country I do not find this servo and I must replace him with what I have. We all have S90 to try.
Thx

While you're correct that our servos are the least expensive High-Torque Servos on the market to our knowledge, I think dolphin_max might have been saying that lower torque servos would suffice for the application. This might be true, considering that Zowi, BoB, and OTTO all use lower torque servos. We designed these servos with a wide variety of robotics applications in mind, such as hexapods and robotic arms, which both require a high-torque servo to operate well. Thank you for pointing out that RobotGeek Servos are High-Torque, we actually take quite a bit of pride in the engineering that went into them. Another Feature of our servos was inspired by the Dynamixel Servo line, which has an Idler horn and side rails for mounting brackets. This lets users build and create without having to sacrifice time that would otherwise be spent working around the problems with mounting points that weren't designed with robotics applications in mind. We also wanted to make a servo that wouldn't break the first time someone new with robotics made a mistake.

We'll make a video demonstrating the value of having a High-Torque Servo to clear up any confusion about this in the future. Would you kindly refrain from getting mad on the internet in this thread again, rx7driftking?

Excellent answer!!!.

We are running a contest with Chip-E, which is marketing for our brand. We just want to be noticed because we think we've got a good system for people to get started with Arduino while making cool robots. Nobody is required to purchase anything to participate. If you read the rules it is clearly stated there. If you do decide that you want to purchase Chip-E (which would be awesome because we're a small business and we like being able to pay our employees), we're offering a 20% discount on the kit! If you don't like our servos, you could make a variant of Chip-E that uses other servos! If you submit the remix to the contest, you'd be in the running to win a PhantomX AX Hexapod and several other robots!

Hey I would like to make a model for the competition but I don't use sketchup and solidworks dosen't work with .stl
can I get a .STP file by any chance

Alright, the files have been added in .step format! Happy Remixing!

Hey sorry to be a bother but could I get .stp files of the metal brackets and servos
so I can make a proper assembly.

Thanks

XL Bracket and RG Servo step files have been added to this thing.

Not a bother at all, we're kind of kicking ourselves in the rear for not having had the step files for those already up. They'll be up shortly.

thanks can't wait to see what everyone makes

Thank you SO much! I use Cubify Design, so I can import .step just fine. Like you said, an .stl is just lots of triangles. My entry coming soon! Thanks for doing the contest, and thanks @shuki for asking!

You're welcome! We'll include step files for everything we make in the future, because we want to give everyone the tools to modify things as they see fit. Seems silly that we haven't, come to think of it.

Give me some time to work on this. Sketchup exports as a mesh, rather than T-Spline or something useful to CAD programs, so I can quickly export it as a step file by importing it to Fusion360, but it has triangles EVERYWHERE. I'll essentially have to rebuild it in a CAD program so it's not gross, which is going to take a bit.

My 2 cents, this seems like a big marketing scam to increase sales at robotgeek, Servosx4 $100

gotta be cheaper servos that would do the same thing

dude it's obvious marketing, they're a store. but they don't seem to be twisting anyone's arm to buy their shit. Even in the comments here they suggest another thing that uses cheaper servos. Why don't you look for cheaper servos that work better and help everyone out instead of being all butthurt? Nobody's forcing you to do anything. 0/10 my dude, figure out how shit works and git gud my 2 cents

Hey people, can we not fight here, please? This is supposed to be a fun place for people to collaborate and create something great together.

If you don't like our servos, you could make a variant of Chip-E that uses Parallax Servos! They're just over half the price of ours, similar in size, and nearly as strong. If you submit the remix to the contest, you'd be in the running to win a PhantomX AX Hexapod and several other robots!

Don't be rude to each other. Life is short, have some fun.

Can you use parallax servos instead?

Parallax servos are electronically compatible, but the rail system is specific to RobotGeek Servos. You wouldn't be able to use this shell without modification if you were to try parallax servos. You could make a Zowi: https://www.thingiverse.com/thing:747010 instead if you would prefer to use cheap servos.
