Synwax vs nxt robot
Let me give you the TL;DR right off the bat: In the long run, you can move into their VEX EDR line, which offers synwax vs nxt robot structural components made of metal and upgraded electronic components. If you would like to know more details, and why the EV3 was a better choice for me and might be for you too read on.
Both feature similar looking plastic pieces, with wheels, axles, etc. However, they are in no way compatible with each other and thus no parts can be interchanged between the sets. EV3 comes in two separate versions. The two EV3 sets have some differences in included components, and the robots that can be built out of the box differ too. All three kits have about the same number of robots that can be built out of the box with the starter kit, but within those robots there seem to be more variations on the EV3 side: While that might sound shallow, consider that synwax vs nxt robot you have kids involved, having cool robots is a significant plus.
I also like the tips that you get at the beginning of the build instructions, e. With the Education core set: And once you add the Education expansion set: In this, the EV3 sets do a great job. For one, it seems to have some larger plates and beams which should make it easier to build larger robots. The IQ set has thinner pieces that require more bracing, but they also allow bending, which would expand the range of possibilities, and the elasticity makes them less likely to fall apart when bumping into things or falling off obstacles.
On the other hand, the EV3 uses LEGO Technic pieceswhich opens the door to a whole large world of kits and builds, including the possibility of automating some of the Technic sets.
Furthermore, one can also add regular LEGO blocks in the mix, which is a ridiculous reason to pick the EV3 over the IQ, but it might allow you to include younger children into your building activities.
The VEX IQ feels like it has the upper hand with a host of regular gears, from 12 to synwax vs nxt robot teeth in a variety of colors, to sprockets and chainsto racks, worms, and slidesto differentials. The EV3 has a similar range of gears from 8 to 40 teethsprockets, racks, etc, but also includes a synwax vs nxt robot different take on turntable gears: The Home kit comes with a pair of fixed-size rubber tank tracks; the Education kit has an link-based chain that can be used to build either tracks used by the Tank Bot and Znap from the Expansion setan assembly-line Color Sorter from Core set or even creatively synwax vs nxt robot the Stair Climber bot.
The Education set also comes with one interesting part: Unsurprisingly, the VEX IQ set does it one better, with cool omni-directional wheela complete set of tracks with various insertsand even a separate set of chains and sprockets.
I like the VEX sprockets and chain for distributing load over large distances. No need for an idling gear to run 4 wheels with 2 motors. The chains and tank treads are adjustable in length unlike the fixed size rubber treads in the LEGO set and you can use the chains for different conveyor mechanisms by attaching different size flaps at whatever interval you want.
Similar to the motors, the VEX IQ sensors seem to be smaller in size, which does synwax vs nxt robot in almost any construction you plan on synwax vs nxt robot. From a connectivity perspective, the EV3 is better equipped out of the box: VEX IQ comes with a rechargeable battery in the starter kit.
Probably not significant, but in additional to the better battery chemistrythe EV3 set allows the battery to be charged without having to take the model apart. The ultrasound sensor tends to be more precise at larger distances, but due to its nature it suffers when the reflecting surface is sub-optimal: In contrast, the infrared sensor works off reflecting light synwax vs nxt robot it suffers synwax vs nxt robot from these issues, however it has its own set of problems, the main one being light polution causing the sensor to only be effective at short distances.
Both types of sensors have an active scanning mode and passive receiving mode enabling the synwax vs nxt robot sensor to act as a receiver for a remote, e. EV3 Infrared beaconwhereas the ultrasonic sensor can act as a noise detector. The kits come with sensors capable of detecting multiple colors, but also measure relative ambient light level comes in handy for follow-the-line robots.
That would put the IQ synwax vs nxt robot at 14 colors vs 8 for the EV3. There are bump sensors in both kits and they function the same; they take a low pressure to trigger and can register three states: In both cases you can attach other elements to them, e. In terms of signaling, the EV3 relies on the brick: In contrast, the VEX IQ set offers a combination Touch sensor with LED that is truly touch-triggered, but it can also use the embedded LED lights to display some 16 million color variations, in addition to being able to blink at specified rates.
Offering a separate LED signaling device means that not only it can be placed in a prominent place, but that more than one can be attached to the controller. Both kits use, apparently for safety reasonsproprietary connectors on their cables. There are two dimensions to consider when it comes to the software part of your robot: The default programming environment for the EV3 is LabView-based, using a metaphor of various types of blocks to represent sensors, actions motors, speakerdata operations on variablesinstructions loops, etcand some advanced blocks manage files, BT, system.
It also comes in two versions, a Home version and an Education version, both free, purposefully mirroring the two EV3 sets because each version builds robots specific to the parts that come with the respective sets. The apps, in all their variants contain both step-by-step building instructions, as well as the programming environment.
Again, you have a full-blown version of Linux, so pretty much anything you can do on Linux, you can do on the brick. One interesting sofware component that the EV3 set comes with, although only in the Education set, is a datalog block. This allows the brick to record high-sample sensor data, for example data from a temperature sensoror truly any of the other sensors. The data can be obtained and viewed in the LEGO Mindstorms app either on the fly, when the brick is connected to the computer, or at a later time.
There are more competitionsbut the kits used seem considerably above the EV3 and IQ levels. Between included components and low prices, VEX IQ feels like the right generation platform for entry-level robotics education or competitions.
The EV3 is a power house when it comes to processing capacity and the availability of components, both in loans from the Synwax vs nxt robot sets as well as third parties like Mindsensors or RobotShop. As a software engineer doing this for fun, the processing power available to the EV3 brick was ultimately more attractive to me than the benefits offered by the VEX IQ set.
A great many thanks to Yusuke Morita for his advice, enthusiasm, and ability to carefully review looooong posts without dying of boredom. Robots and Instructions All three kits have about the same number of robots that can be built out of the box synwax vs nxt robot the starter synwax vs nxt robot, but within those robots there seem to be more variations on the EV3 side: Who could resist the adorable Puppy robot Education set?
For beginners, those kind of tips can save a lot of time and frustration. Gears When it comes to gears, it becomes a bit synwax vs nxt robot difficult to make synwax vs nxt robot straight comparison. My good friend Yusuke says this of the offer: Brick The brain, aka controller aka brick, is where they differ significantly.
Y Y 1 Encoder accuracy 1 deg 2 1 deg 2 0. EV3 encoding accuracy can be doubled to 0. The smaller physical size of the VEX IQ engine means that it can be used in more compact synwax vs nxt robot, or in tighter spaces; the larger size of the EV3 motors means it can be part of your structure or structural reinforcement. Distance Sensors There are two types of distance sensors: Receive Mode Yes Yes 2?
Bump aka Pressure Sensors There are bump sensors in both kits and they function the same; they take a low pressure to trigger and can register three states: Cables Both kits use, apparently for safety reasonsproprietary connectors on their cables. Software There are two dimensions to consider when it comes to the software synwax vs nxt robot of your synwax vs nxt robot To be honest, in terms of features and pricing, EV3 has the upper hand.
By a wide margin. Programming The default synwax vs nxt robot environment for the EV3 is LabView-based, using a metaphor of various types of blocks to represent sensors, actions motors, speakerdata operations on variablesinstructions loops, etcand some advanced blocks manage files, BT, system. Final Words Between included components and low prices, VEX IQ feels like the right generation platform for entry-level robotics education or competitions. Stay tuned for a post on which of the EV3 sets I decided to go with and why.
