Motors, sensors, battery: anything in common?

We strongly recommend that you do this before purchasing your kit, to make sure all your hardware and operating systems meet the minimum system requirements . This site is dedicated to amateurs and makers on the lookout for topics around new technologies and robotics, or tutorials and tests on our new products. However, prototypes of the key element of every set – programmable brick – were being developed even earlier, in 1987.Wide possibilities of the set and simple building system make it possible to conduct a full robotics lesson (introduction, building, programming, and testing) in a surprisingly short amount of time. This quality is absolutely unique among robotics sets available on the market. No wonder the series has a reputation for being one of the best tools for teaching robotics. The tray with 13 compartments allows you to easily sort bricks according to their size and purpose. Sorting makes it possible to build fast, with no need to spill bricks on the table, or on the floor. What’s more, the building process becomes less noisy, which will surely be appreciated by teachers using these sets on an everyday basis.

Inside the box, in addition to 541 elements, there’s a cardboard list of bricks that facilitates sorting the elements and a paper instruction on how to build a simple vehicle. The box has a fetching image on it, which definitely increases sales figures, but serves poorly as storage. If you cut it along the line, you’ll find a simple testing mat on the reverse, helpful when working with the color sensor. In addition to electronics and construction elements, the set contains a sticker sheet to decorate several parts, and a paper instruction on how to build a robot. The differences lie in the amount, types and colors of these bricks. The set also contains axles of 10 different lengths and 3 types of axles with end stop. In order to connect axles with beams and frames, you can use 7 types of pins (which include smooth and friction pins for creating connections of varying strength), or one of 18 types of connectors, axle to pin ones included. For blocking, or separating bricks on an axle, you can choose from 2 types of bushings, or pin joiners (also known as tubes). Education set has 10 different kinds of gears (normal and bevel ones) and two small turntables. Connect them with sprocket wheels and you’ll create a perfectly functional chain drive. Vehicles with such a caterpillar drive advance well enough, but since the plastic surface is smooth, some gliding may occur. Nonetheless, you can always buy these elements separately. The list of slightly less useful bricks is limited to 4 black panels for encasing completed constructions and 4 decorative “fangs”. This set version is dominated by black bricks, with some red and grey ones. White elements, such as panels or blades, are purely decorative. Unfortunately, this color palette impedes the building process. It’s difficult to recognize particular parts in the black mass, so finding the one you need (remember there’s no sorting tray) takes more time. The black color also has a negative influence on legibility of building instructions. Moreover, there are no colorful bricks to use with the color sensor. Normal axles are available in 6 lengths only, but you have at your disposal 5 types of axles with stops. For connecting them, the producer offers 6 kinds of pins and 21 types of connectors. Gears are available in 8 variations, which in total gives you 21 elements for creating gear mechanisms. No turntables are included in this version. To create vehicles, you may use four black tires with fitting rims.

8 Major Differences Between Mindstorms EV3 Education and Home EditionInto Robotics

Caterpillar drive can be achieved by using rubber caterpillar tracks, which have good traction. Unfortunately, these tracks are quite fragile. If used often, they may stretch and stray from drive wheels. Sometimes, pins may get damaged while dismantling the construction; children tend to “bite” them out, in spite of reminders. With intense use, teeth of the smallest gears can wear out. However, as a teacher, you should be more concerned that tiny elements of the set tend to get lost. If you’re organizing a robotics workshop in school, you should buy one of every kind. This way, even if some parts do get lost, your workshop will be able to operate without any forced breaks. This expansion comes in a separate plastic box of the same size as the base set. Therefore, in order to efficiently work with the expansion, you’ll need to have sufficient working space to handle two large boxes. This expanstion is definitely a welcome addition.

More cogwheels and beams allow to create mechanisms that are more efficient and more accurate; they also make the overall building process more productive. Differences become visible when you take a look at sensors. Depending on the version you choose, you’ll get a different number and type of sensors; even the applied technology will differ. Motors and sensors can be connected with the brick by means of cables with plugs. Cables constitute the only element that wears out considerably soon, because plugs get damaged easily. Moreover, relying on it is not the best choice due to time limits. Charging it takes a lot of time, during which you clearly can’t use the set. All motors have a built-in rotation sensor.

One of its possible uses is to coordinate two motors present in one construction, so that the robot advances straight forward. Rotation control in both types of motors is very precise (up to 1°), thanks to the built-in tachometer. Large motors have higher power and a big rotating head, which facilitates drive transmission. The smaller motor is capable of higher speed (up to 250 rpm) at the expense of the power available. Thanks to its size, it can be easily incorporated into numerous constructions.

You can use it to run or stop operation of a construction, to create bumpers, or to count button presses. It collects data concerning colors (distinguishes 8), or light intensity (ambient, or of a reflected beam). Composed of several accelerometers, this sensor measures angular position and can detect changes in the position of an object with the accuracy of 3° in all axis of rotation. Depending on the set version, a different technology is used to measure distance. It produces ultrasonic waves, which upon encountering an obstacle rebound and return to the sensor. The distance is expressed in units of somewhat vague definition and is often misleading.For this end, you have 5 programmable buttons at your disposal (and their combinations, so 11 programmable actions in total). The very first problems appear only after a few years of intense use. Purchasing additional cables (they break down first) and individual electronic modules is definitely worth considering.

You can access it on computers and tablets. Programs are created by dragging individual instructions to the start block. Every instruction block can be adjusted through various options.

Programs are created easily, almost intuitively, and all block options are visible right away. The only problem concerns the size of the blocks. Longer, more complex programs don’t fit on the screen, which forces users to scroll the preview. This flaw makes the process of creating advanced programs slightly inconvenient. However, it’s rarely a problem for projects executed during school robotics classes. The last method is perhaps plain, but trouble-free.

You have access to only 3 palettes out of 6 available on the computer version.

You won’t find any data, or advanced blocks, and you certainly won’t be able to create any blocks of your own. The tablet app version allows you to create only the most basic programs, which potentially restricts the knowledge one could gain. Android devices, no specific requirements were defined. The list of compatible devices can be accessed here . It contains several instructional videos that guide you through the possibilities of the app. All models are interesting, but also complicated to build and program, so the entire process of assembling them, creating their programs and testing takes a lot of time.Note that instructions do not cover step-by-step programming. As soon as you complete building the robot, you get an already finished, complicated program, which may be hard to understand at first glance. Unfortunately, immediate access to a completed program impairs the educational value of the project; students don’t get the chance to create the program from scratch, they don’t test it, or correct programming mistakes. Together with programming instructions available in the programming tutorial, this straightforward construction can become a base for many fascinating lessons. Tablet version users have a very limited choice. They allow users to create and test programs on their own. In other projects, the advanced programs are presented already complete with commentaries only. Again, completing them takes time, which hinders potential class use. In the tablet version, the app looks quite similar. The building system is easy and quick, the elements are durable. Construction and electronic elements are diversified, which equips teachers with basis for earnest teaching of elementary mechanics and physics. These sets also develop creativity, because they encourage testing out individual ideas. Undeniably, they have wide possibilities and can be used even on higher levels of education. It allows users to create advanced programs easily, in an intuitive manner, which fosters computational thinking and helps beginners to understand basic concepts without any need for learning complicated syntax of text programming languages. The differences between the two versions available on the market seem small at first glance, but concern the parts most essential to teaching. This version has a useful box that facilitates storing and quickens building thanks to the sorting tray; the construction elements are better thought-out; the sensors are more interesting; the programming app provides more options; the robot models constitute a better base for learning. All these factors have a positive influence on the lesson flow and enable teachers to conduct a full robotics lesson (introduction, building, programming and testing) even in 90 minutes. This version has neither tools for collecting and presenting data, nor any material for the teacher. The table summarizes our evaluation of both sets. However, it’s worth noting that these differences are also reflected in adequate prices of respective versions. Additional educational material is helpful with both versions. By consequence, they take too much time to be efficiently applied during normal school classes. Sample exercises are available for free in our demo course . The retail version has a focus on fun, while the educational set has a focus on learning. The retail version comes with a total number of 541 pieces, while the educational version comes with more than 550 pieces. Are there any reasons you can think of that he would be disappointed with the retail set?
