  • Rideable Segway Clone - Low Cost and Easy Build

    Hi Ira,I almost gave up the construction, but I think I spent a lotof time on it, and it would be a shame.So here's a new question:I read in the instructable that the geared motors weresensitive to the back slashs. In addition, the gears generate a free play which must disturb the proper functioning ofthe gyroscope. Also, I intend to remove the gearbox and replace it with asprocket and a wheel as you did.With a sprocket with 11 teeth and a wheel with 66 teeth, theratio is 1/6.Your engine runs at 2650 RPM, so 440 rpm per minute on thewheel.The engine I use runs at 4900 RPMWith the 11-tooth sprocket and the 66-tooth wheel, the wheelwill run at 816 RPM.We go from 440 RPM to 816 RPM.The difference is quite significant.Can it be taken into account in the Arduino code, or is itnecessary to ...

(could be the ACC_GAIN ?)Best regards,Jean-Claude.

    Hi Ira,Thank you for your reply.You advise to reproduce the malfunction of the rotating wheel to draw hypotheses.In fact, the fault is always present at power up and without having to press the dead man switch.Unfortunately, I have no other elements apart from the fact that the 2 motors I use come from an old wheelchair. They are probably more powerful than the motors you use.In the instructable's, you also wrote that gear motors are more prone to hooking (back lash). Do you think it is better to have a softer system with a chain transmission. If so, I could try to keep my actual motors, removing the gearbox and replacing it with sprockets and chain.Regarding the question I posed in my previous post, you do not answer directly. It is true that my English is not perfect, and it is possib...

It is true that my English is not perfect, and it is possible that I have expressed myself badly.That is why I ask it again in other words:2 - According to you, a wheel that rotates slowly does not affect the driving of the clone segway1 - always according to you, it is an electric noise that causes the wheel to turn3 - EFI or EMI electrical noise can disturb the I2C bus4 - so, as long as a wheel rotates slowly, this means that there is electrical noise and therefore the system is not reliable because the I2C bus is exposed to disturbances5 - in fact, and in short, a spinning wheel is actually an alertDo you agree with my point of view?Best regardsJean-Claude

    Hi Ira,I continue my investigations to have a good functioningIn view of the various comments in the instructable, I see that there are several people who have the same dysfunction, namely a wheel that turns slowly. According to you, this is due to a noise in the system. You also point out that the system noise can have a bad effect on the I2C bus with all the consequences we know (motor going mad, vibration)So, am I right with the following assertion:"As long as you have a slowly rotating wheel, it means that the bus can be disturbed by the motors whatever the reason either Radio Frequency Interference (RFI) or ElectroMagnetic Interference (EMI)"In short, seeing a slow-moving wheel is an indicator of malfunction, and even if it does not interfere with driving, it is very impo...

    Hi Ira,I think the issue I face could be due to gear motors I use. They are quite powerful and need very high curent The Sabertooth card has to dealwith regenerative current.So my intention is to make a try with same motors you use.You are using motors 280 W and batteries 7Ah. So, have you anidea of the autonomy ?Is there a method to calculate autonomy when we know power ofmotor and batteries capacity ?Best regardsJean-Claude

    Hi Ira,To me « autonomy » is the time you can drive thesegway (in terms of hours and minutes) before the batteries run out. You maycall it « battery life »As an example, I have made a very basic calculation :Motor power 280 W / 24 V = +/- 12 AWith 2 batteries 12 V 6 Ah in serie, the segway could run intheory half an hour.Am I right ?Best regardsJC

    Thanks for your answer.All point you preconize have been already taken in account (one point tie ground + wires twisted bypair + connection as short as possible + pull resistors + battery fully charge+ DIP configured as indicated in the instructable + wire with very largesection)The wiring has been verifiedagainst the schematic, and the construction is quite neat.So now, I am a bit disappointed,and I am about to give up. To me, the only solution seems to find a local hightlevel technician to find out what could be wrong.Best regards.Jean-CLaude

    Hello Ira,After a long period of inactivity, Iresume the development of my segway clone.My Sabertooth card has been repaired bythe manufacturer (fast and free repair)This is the report of the after salesservice :The damage was caused by the inhibitionof the regenerative current. If the motors could be spun when poweris switched off from the 2x25, then use a power switch in parallel with adiode.In my case, I use two motors with anangle drive (worm). Therefore, it is not possible to run the engine by rotatingthe wheel.So I do not really know why the card wasdamaged.Now, I am able to repeat the tests.There are still two malfunctionshttps://youtu.be/-rDSIh0no_k1 - direction of rotationBy tilting the gyroscope towards therear, the motors also rotate towards the rear.

So it's normal. On the other hand, by tilting thegyroscope forward, at the start the engines turn forwards, but from a certainpoint, they turn towards the rear.In addition, the forward speed is slowerthan the reverse speed.2 - motors vibrate and stopAt random, engines behave abnormallyI changed theMPU6050_6Axis_MotionApps20.h library by changing the last number, but that doesnot change anything.I use engines that are very differentfrom yours. They must have a more powerful torque, and must use a highercurrent. Would any gain and sensitivity parameters be changed in the code?Thank you in advance for your helpJean Claude

    Hi Ira,Still on the infernal machine...Back to my video :1 - Well seen, around 47 seconds, you noticed two wires on S1 at the Saber. It’is a very short lenght of wire which is use to grip the oscilloscope probe.2 – I confirm that there is a direct link beteween S1 at the Saber and Pin 13 at hte Arduino. This wire is twisted with ground connection3 – you tell me to modify arduino code in order to test the Sabertooth. I am unable to do this job. So, I have dowloaded a test progamm witch take in acount exactely the same hardware. I shall tell you the result of the test.4 - I have read one more time the instructable, and I have discovered one thing I have not done properly.I have not added one individual wire to both twisted pair. I consider if you mention to do so, it mus...

    Pringle Can MIDI Drums

    Hi,I have finished the system, but it doesn't work.The led flashes according pression on the sensor. So, it's not so bad...In fact, I think I have found the reason.I have connected the output directely in a audio amplifier input.When I read the instructable you mention MIDI signal, which normaly is a logical signal and not analogic.Could you confirm that ?If I am right, could you give me a link to a simple and free MIDI player for a pad.Many thanks for your helpJean-Claude from France

    HiI have downloaded a MIDI application for my pad.So, how to connect the output of Pringle Can MIDI Drums to the pad ?Probably via the USB port, but which wiring ?Many thanksJean-Claude from France

    Hello Ira,A few months ago I posted some questions of course about the constructionof the segway clone.At the time, there were several dysfunctions. Then, I modified the wiring,and I changed the gyro card, so thingsgot a bit better.For personal reasons, I put the construction a bit off, and I'm recoveringnow.There is something weird about the Sabertooth card. That's what happens:I turn on the power (24V)I wait for 8 secondsI do not press the deadman switchIf I connect a voltmeter to the M2A / M2B output of the Sabertooth board, Imeasure 0 V with a voltmeter in DC position and +/- 3.75 in the AC position. So, the motor rotate veryslowly. Here is the picture of the signal.f I do the same on the M1A / M1B output, I measure 0V both mode (DC andAC). Here is the picture of the oscilloscope o...

Here is the picture of the oscilloscope on this channelIn addition, here is a picture of the signal that comes out on pin 13 ofthe Arduino card (still without pressure on the dead man switch)If I press the deadman switch, the operation is eratic with apparently anIC2 bus break.Of course, all your advice has been followed (wires twisted by pair +connection as short as possible + pull resistors + battery fully charge + DIPconfigured as indicated in the instructable).To be sure to be completely free from possibleparasites, I tried to power the arduino card with a 9-volt battery, but thatdoes not change anythingHere are some questions:Since the fact that motors do not turn, I consider thatparasites cannot interfere on the system – Yes or no ?Why are the signals on the two outputs different?Is it normal to have a signal on pin 13 of the Arduino card withoutpressing the deadman switch ? To me, it would be seem more logic to get nosignal at all.What kind of signal should be read on the pin 13 either without pressure orpressure on deadman switch ?Is my signal seen by the oscilloscope on pin 13 correct ?An Arduino card is very cheap and easily available. So, Icould try to connect a new one. On the other side, a Sabertooth car isexpensive. How could I be sure that my sabertooth card is fullyfonctionnal ?Many thanks for your help.Best regards Jean-Claude (France)
