The Best Way to Lure the Company for a Few Evenings. Overview and Assembly of the Arduino-Constructor Keyestudio KS0551 With Ilon’s Wheels

I wel­come every­one! The design­er KS0551, based on the Arduino KEYESTUDIO, fell into my hands. KEYESTUDIO is a fair­ly pop­u­lar Chi­nese brand that devel­ops edu­ca­tion­al kits relat­ed to the pop­u­lar Arduino and Rasp­ber­ry micro­con­trollers. This kit is based on a mod­i­fied Arduino Uno with many sen­sors. A fea­ture of the design­er is the use of Ilon’s wheels, or as they are also called “Swedish wheels”, capa­ble of any trans­port, not only in all pos­si­ble direc­tions, but also to dri­ve diag­o­nal­ly. Assem­bly of the con­struc­tor takes sev­er­al hours, the process itself is incred­i­bly inter­est­ing, fun and infor­ma­tive, but not with­out nuances, which I will write about lat­er.

The design­er from Keyestu­dio arrives in a col­or­ful brand­ed box, which con­tains the appear­ance of the fin­ished mod­el, its main fea­tures and advan­tages.

The con­struc­tor is quite com­pact­ly packed in a box. In addi­tion to all spare parts, there is a book­let list­ing all com­po­nents and their quan­ti­ty in the set. On the reverse side there is a QR code lead­ing to a page with instruc­tions.

In gen­er­al, the com­plete set of the set is shown in the pho­to below. It is worth prais­ing the man­u­fac­tur­er for putting a mag­ne­tized screw­driv­er, and quite good qual­i­ty. How­ev­er, all com­po­nents are made very high qual­i­ty.

In the fol­low­ing, the main com­po­nents will be pre­sent­ed in more detail. The main “base” hous­es the main sen­sors, LEDs, and con­nec­tors for con­nec­tion. It also hous­es a bat­tery com­part­ment designed for 18650 bat­ter­ies.

The main board is made very high qual­i­ty, the sol­der­ing is excel­lent, there are no traces of flux. This board is an ana­logue of the noto­ri­ous Arduino Uno, with some changes: the pads with dig­i­tal sig­nals 3, 5, 6, 9, 10, 11 and ana­log A0-A5 were removed and the con­nec­tion inter­face was changed to Type‑C.

In the next box, the user is greet­ed with an expan­sion board, aka Shield. In this mod­el, it serves to con­ve­nient­ly con­nect all com­po­nents. As with the main board, the work­man­ship is excel­lent.

The last box con­tained all the oth­er com­po­nents: remote con­trol, ultra­son­ic prox­im­i­ty sen­sor HC-SR04, Blue­tooth mod­ule, con­nec­tors, ser­vo and a set of screws.

In this sec­tion, the assem­bly of the mod­el was car­ried out, as well as some notes dur­ing assem­bly, which will facil­i­tate it. Assem­bly begins with attach­ing the ultra­son­ic prox­im­i­ty sen­sor to the plat­form.

Next is fix­ing the ser­vo on the same plat­form. Care must be tak­en to install the ser­vo cor­rect­ly, as shown in the pho­to below.

After fix­ing all the details on the upper plat­form, we move on to the low­er plat­form. It is nec­es­sary to find a cross-shaped noz­zle on the ser­vo and 4 self-tap­ping screws and fix it to the plat­form as shown below.

Pay­ing atten­tion to the fact that before installing the ser­vo on the noz­zle, it is nec­es­sary to pro­gram­mat­i­cal­ly rotate exact­ly up to 90 °. This is done in a sim­i­lar way: the ser­vo is con­nect­ed to the main board to the con­tact group D11, IMPORTANT observe polar­i­ty. The orange wire from the ser­vo should be on the yel­low back­ing, red on red, black on blue.

You should also remem­ber to con­nect the con­troller to the com­put­er using the sup­plied USB Type‑C cable and launch the Arduino devel­op­ment envi­ron­ment. For the cor­rect oper­a­tion of the ser­vo and all oth­er com­po­nents, I rec­om­mend installing the man­u­fac­tur­er’s libraries (link lead­ing to the page with libraries). In the “tools” pan­el, the Arduino UNO board must be select­ed and the COM port select­ed. Enter the code below, com­pile it and, if there are no errors, upload it to the con­troller.

When the ser­vo has turned at a giv­en angle, a plat­form is installed on its out­put shaft, on which the noz­zle for the ser­vo is locat­ed and fix it all with an M2 screw.

We pass to the main base. We fix the main micro­con­troller on 4 racks and tight­en the screws on both sides.

On the reverse side is the instal­la­tion of mounts under the engine.

The engines them­selves are placed on the installed mounts and con­nect­ed to the near­est con­nec­tors.

Plas­tic clips are installed in the wheels them­selves.

Next, you need to place the wheels exact­ly as shown in the pho­to. The rollers must be direct­ed in dif­fer­ent direc­tions, this is nec­es­sary for the cor­rect move­ment of the machine.

We return to the upper side and to the main body of the rotary part with an ultra­son­ic prox­im­i­ty sen­sor and a ser­vo.

The next step is to install the expan­sion board into the main board.

It is also worth remem­ber­ing to install the Blue­tooth mod­ule. Pay­ing atten­tion to the fact that this mod­ule needs to be removed.when the code is loaded into the micro­con­troller itself, oth­er­wise an error will pop up.

Let’s move on to con­nect­ing the ultra­son­ic prox­im­i­ty sen­sor. We con­nect the wires in the fol­low­ing order: VCC (sen­sor pow­er) — red wire, Trig — blue, Echo — green, Gnd — black. In no case should you con­fuse the col­or of the wires and the sequence, since there is a great chance to dis­able the sen­sor.

We con­nect these wires to the con­tact pad shown below in the pho­to. Don’t for­get to con­nect the ser­vo as well.

Next, con­nect all the wires, accord­ing to the instruc­tions.

For the design­er to work, you will need to pur­chase 18650 bat­ter­ies. I used one of the most capa­cious bat­ter­ies of this for­mat — NCR18650 from Liitokala, which is a com­plete ana­logue of the Pana­son­ic ver­sion used in Tes­la cars.

To under­stand the sever­i­ty of the prod­uct, I checked the mea­sure­ment with Xiao­mi ATu­Man Duka ES1 scales with­out bat­ter­ies (470.1) and with (565.6 grams).

The fin­ished machine looks like this:

After assem­bly, it is nec­es­sary to check the oper­abil­i­ty of all con­nect­ed sen­sors. Sketch­es are in the cloud at this link. Briefly go through all the lessons:

  • Les­son 1 — checks the per­for­mance of the LEDs locat­ed on the main body

  • Les­son 2 — per­forms sim­i­lar actions from the last les­son, but with LEDs locat­ed on the back side

  • Les­son 3 — smooth­ly rotates the posi­tion of the ser­vo from 0 to 180 degrees, and vice ver­sa.

  • Les­son 4 — checks the per­for­mance of all 4 engines

  • Lessons 5 and 6 — set­ting up and the firmware itself for mov­ing the machine along the black line

  • Les­son 7 — check­ing the oper­a­tion of the ultra­son­ic prox­im­i­ty sen­sor (the dis­tance to the near­est object is dis­played in the port mon­i­tor)

  • Les­son 8 — the car will fol­low the object in front, stand or back, you can set the dis­tance your­self

  • Les­son 9 — avoid­ing obsta­cles using an ultra­son­ic prox­im­i­ty sen­sor and a ser­vo. The car “looks” for the short­est way to go around the obsta­cle and goes around it

  • Lessons 10 and 11 — remote con­trol of the robot through the remote con­trol

  • Les­son 12 — remote con­trol of the robot through an appli­ca­tion on a smart­phone. Unfor­tu­nate­ly, I can’t check, because the smart­phone flat­ly refus­es to con­nect to the machine.

Below is an exam­ple of how a car is able to move because of its wheels. The machine was con­trolled through the con­trol pan­el.

As was the case with past design­er from KEYESTUDIO, who have been in my hands, this set is able to enter­tain the fam­i­ly for more than one evening. I have prac­ti­cal­ly no com­ments on the set itself: all the details are of excel­lent qual­i­ty, the instruc­tions are also very detailed, with step-by-step illus­tra­tion (evens out the fact that it is in Eng­lish). But I can­not help but note that the robot did not con­nect to the smart­phone appli­ca­tion, which slight­ly spoiled the extreme­ly pos­i­tive impres­sion of this con­struc­tor. Is it pos­si­ble to do with­out the app? Of course, almost all the declared func­tions work with the con­trol pan­el includ­ed in the kit. This set is a great gift for your child / hus­band / broth­er / father-in-law / father or girls with a tech­ni­cal approach. The con­struc­tor will give an under­stand­ing of how the pro­gram works and teach you the basics of pro­gram­ming. Can I rec­om­mend this set for pur­chase? Of course, I had a lot of fun with the build process and cus­tomiza­tion.

Buy this kit with a design­er KEYESTUDIO KS0551 you can in the offi­cial KEYESTUDIO store, and giv­en the biggest sale this year, the price will be a lit­tle nicer.

In addi­tion, I sug­gest that you famil­iar­ize your­self with the col­lec­tions of sim­i­lar sets:

  • 10 pro­gram­ma­ble elec­tron­ic kits from Aliex­press
  • 10 elec­tron­ic design­ers on Arduino from Aliex­press

Thank you for your atten­tion.
