KOOKYE Robot Car Tank Electronic Parts Chassis Platform Components Set Arduino Hands-On DIY

Dont buy, the advert is false advertising, it does not include the chassis despite all the misleading photos implying it does

I was getting very excited that I had found a robot car/tank at a very reasonable price. But as they say “all that glitters is not necessarily gold”. Ifyou read the ad carefully you will find out that dispite the pictures the electronics kit does not come with the chassis, Which you have to buy separately for another £80 odd. When I bought my first Arduino kit I received all the items IN the advertising photos. I wonder how many buyers have been tricked by this false advertising and just can’t be bothered to leave a review. This advert is misleading and should be reported to Trading Standards (in the UK).

 Awesome. No problem with obstacles. Plenty of power. I was worried when I read some of the other reviews but I think maybe they just had problems in their sketch. I have mine loaded down with a pi ,arduino , custom 4 servo claw ,LCD touchscreen, l298n ,ptz night vision camera, hc05 bt module and a breadboard . Running full range of motion with the arduino , hc05 and Bluetooth app. I have the dc encoder motors running at 12v only using red and black leads and a single $7 l298n motor controller with a pretty small dewalt lithium max battery .it's stepped down to 5v for the arduino and arm servos as well through the same l298n. It will run 20 min plus on one charge. Pi runs the camera/ recording and a few other featured and powers off it's own hat/ 3.3v supply. All together its pretty heavy and it still has power . Motors running at digitalWrite speed of 225 for full forward and reverse. Left/right turns same speed just reverse direction of one motor. Forward and turn i just changed speed of one motor to 180 . So forward left is 180 speed to left motor and 225 right motor in the sketch. See my videos. Very happy with it. Do wish the tracks were softer. Hard plastic slips on smooth surfaces. I put large rubber bands on the tracks and it helps a lot

I purchased this device to serve as a platform to create moving time-lapse videos ( hyperlapses ) I needed a carriage that could carry a DSLR , battery and Raspberry Pi with a PWM motor controller and advance in a repeatable distance despite the state of the battery charge. I used the hall effect sensors on the motors to create an odometer of sorts. It worked well enough so far that my goal is nearly achieved, only waiting for better weather. However, the track wheels do have some resistance when the mounting bolts/nuts are too snug. This is due to the plastic sleeve spacers used to align the free wheels in the tracks. They deform slightly and interfere with the smooth rotation of the bearings in the wheels. As a result, my car doesn't track in a straight line but veers to the left slightly which will necessitate a speed correction in my Python software to compensate. I tried to use the hall effect sensor data for this but sadly they aren't matched from motor to motor so I get wildly different counts per the same motor settings. If the mounts were metal this issue might not happen.The tracks come too long and you don't know this until assembly then one must remove segments, two in my case which is annoying and time consuming. Seems to me that they could be fitted to length at the factory. Also, having them rubberized might be an improvement but might make turning harder.Finally, it would be really helpful to get more documentation on the hall effect sensors and the circuit used as I had to do some trial and error to get them to work and am not totally sure that I have the optimum setup.Over all though, the car is spacious, has lots of places to mount hardware and the geared motors seem up to the challenge to carry a significant load. Generally, I am pleased with the product and recommend it for enthusiasts.

The electronics kit arrived quickly, in good shape, and appears to be of excellent quality. However, buyer beware - this kit does NOT include the tank chassis, and the electronic kit is utterly useless without it. This is only made clear deep in the item description. This is likely not deliberately deceptive (the chassis is available as a separate part from the seller), but it is easy to miss. The build quality (all metal) seems good enough to justify the relatively high price, but was not what I was looking for. To their credit, Kookye accepted my return without issue.

Please note that the tank chassis featured on the DVD for this KOOKYE Tank Electronic Parts Kit is not the exact same as the sold-separately Xiao R Geek Big Track Robot chassis so you'll have to be creative with installing the ultrasonic sensor servo motor. On the video, it features a cutout in the plate so the servo can be attached. The new chassis doesn't feature this cutout. However, there were surplus 18mm copper pillars (coupler nuts) in the KOOKYE Robot Tank Car Kit that I used to support the servo atop the aluminum chassis and used the two M2.5x10 for the servo to friction fit inside these pillars. Also, only the QR Code on the front of the KOOKYE Tank Electronic Parts Kit features a wiring schematic to pull up on your smartphone so you will know which wire to connect the sensor wires to on the microcontroller as the DVD is time elapsed. No wiring schematic was provided in the kit itself.

Who every designed the road wheels needs either to go back to school or find some other line of work. They include metal roller bearings but the wheel is then attached by a plastic shaft to the chassis, and if it is tighten too much the shaft will bulge causing the shaft to make contact with the wheel. It is easy to tighten it too much (it's plastic) but it needs to be tighten well or it will turn itself off. When the plastic shaft bulges for some reason the wheel does not want to rotate!
