CUB3 – or not only a cube?

CUB3

Overhead View

A project I almost gave up on; thankfully I didn’t! Built with LEGO MINDSTORMS and Technic components, it includes: 2 EV3 Large Motors, 1 EV3 Medium Motor, 1 EV3 InfraRed Sensor, 2 small linear-actuators, a pair of hidden caterpillar tracks, and more! With its insignificantly-looking cubic structure, CUB3 is engineered to look like your ordinary box just lying around. Decoration, anyone? Your neighbors will find out soon enough. Just watch!

Marker Holder

 

Hello everyone again! Doodl3r is my version of Breberky‘s EV3 Doodler. Doodl3r can draw using a marker by use of a scissor linkage. Two large motors drive the ends of the linkage’s arms at different speeds (depending on what type of picture you want). The basic core of Doodl3r is basically from Breberky’s LDD with a few structural tweaks, but the rest of the design is mine. Special thanks to Breberky who allowed his EV3 Doodler to be worked on by others like me. I recommend checking out his robots.

Load3r

Loa3r

Bucket Down

Bucket Up

Load3r is a simple yet efficient robot inspired by certain construction vehicles known as loaders. The loader design alone took hours to build. The bucket is more complex than it looks. The bucket can also be lifted manually and stowed in place above the vehicle. The tread design is similar to EV3RSTORM‘s. It is remote-controllable via the IR Remote. I know this bot may be a bit of a disappointment compared to my others, but I was really focused on the bucket design more than the vehicle itself. Plus, it is great with pushing foreign objects out of the way. Please be sure to check out my other robots, which are notably better. 🙂

Arcad3Art

Arcad3Art

With this robot, you can design your own colorful paper disk…for a small price 😛 Arcad3Art is very unique in that it is like an arcade machine. I will describe the basic functions here, then explain individually detailed in “Additional Information”. The program starts. Arcad3Art emits a ratchet noise for 3 seconds, then a “success” sound sounds. Arcad3Art responds, “SEARCHING-FOR-OBJECT”. So it waits, just searching for the quarter with the hidden color sensor. You see, you have to pay to use it. After you insert the quart into the coin slot, the designing begins! It even makes a “tick-tock” noise of a clock while the timer’s on! Oh, let me drop this in. All you have to do is cut out a circle of paper the size of a CD (or just trace and cut around one). Then punch a hole through the middle, slide it down the axle, clamp it with the security grip, and you’re ready to go! Get a marker and just press the tip on the surface of the spinning paper disk (the disk is spinning at 250 RPM via the Medium Motor). It will start swirling color onto the disk. The spinning is randomize-timed between 15-30 seconds. It then gradually slows down to a stop. “Thank you,” it replies, and shuts down. Clever, eh?

SumoStorm3r

Finally, the SumoBot I’ve been talking about for sooooooooo long: SumoStorm3r! SumoStorm3r is my entry to SprinkleOtter’s SOSumoBot Challenge. It didn’t take me that long to build SumoStorm3r; the long part was fixing and upgrading SumoStorm3r just right until I was satisfied with the result. As you see, SumoStorm3r is very streamlined and well-armored. It is different from other SumoBots in that it has no weapons or offenses, just one defense: push the opponent out of the ring. Only one LEGO® MINDSTORMS® EV3 set was used!

Compound Gear Train

Compound Gear Train

TOP SPINN3R is a top spinner. (What else could it be?) I got inspiration for this from nxtprograms, but this is not a copy/replica of the nxtprograms NXT Top Spinner. I designed this solely by myself, and I like how it turned out. At first, it was really basic with just the inside mechanics plainly exposed; but I decided to make it look a lot more nicer by creating a streamlined shell for TOP SPINN3R. An EV3 Medium Motor spins at 75% speed (I know that it could be a lot faster, but I used the EV3 Motor Control app which spins motors at 75% speed default). It spins the multiple compound gear trains, which I think are unique. The final gear ratio is 22.5:1, which is ultimately fast. With a loose worm gear transferring power from the 1:18 geared-up axle to the top of the top, the top actually spins along a smooth surface quite well (up to ½ a minute). I built the LEGO Top with a 7M axle and smaller-to-larger gears stacked from bottom-to-top on the axle. The video demonstrated the top being spanned by the TOP SPINN3R.

EV3CLAW

EV3CLAW

Mechanism: Worm Gear-24z Gear

Mechanism: 24z Gear-12z Gear

Mechanism: 12z Gear-20z Gear

EV3CLAW was originally meant to be a robotic arm… It didn’t work out as planned. But it still is something! A robotic claw! The actual claw is at the end of EV3CLAW; a medium motor powers a worm gear, which turns a 24z gear, which turns a 12z gear, which interlocks with a 16z gear and closes the claws. You can see how the mechanism works and how it picks up objects. Enjoy!

myBOBB3E Update

myBOBB3E has been updated a bit. Changes would include decorative swords along the body, an EV3RSTORM look-like head, and a color sensor upgrade. Enjoy! Here’s the URL for complete information and a video: http://www.us.lego.com/en-us/mindstorms/community/edit?ProjectId=d366797a-739d-46fe-aea1-d64568f13f21

myBOBB3E

 

myBOBB3E is simply an upgraded version of the official bonus model BOBB3E. The upgrades include a wider forked arm, minor rear panel re-arrangements, and two added sensors (Touch Sensor and Color Sensor). I geared up the driving mechanism to 5:3 for a faster Bobcat®. Several minor decoration changes were made as well, including the head configuration. Enjoy!

BOBB3E

BOBB3E is an official EV3 bonus model. Do not criticize me; I’m not taking any credit for this. Many NXT owners would probably like to know what BOBB3E is; therefore I am posting BOBB3E. I will also upgrade BOBB3E based on the challenges challenged by the creator of this robot (challenged on the EV3 software). BOBB3E is basically a remote-controlled Bobcat®. BOBB3E can drive around and lift + lower objects with its arm. The driving mechanism is geared down 3:5 to increase torque (unfortunately reducing speed). It also sounds a backup alert when it drives backward. Stay on the lookout for a modified BOBB3E!
