ZK-4WD package, you can achieve the following functions
1, tracing (using photoelectric sensor)
2, find the track + ultrasonic obstacle avoidance (in front of a barrier to stop, display the distance)
3, the aircraft rotation ultrasonic obstacle avoidance (in front of the distance is displayed on the digital tube)
4, infrared obstacle avoidance (such as maze test to avoid obstacles)
5, the function of measuring speed (measuring the speed and distance of the car)
6, Android mobile phone remote control (tracking, obstacle avoidance, remote control three mobile phone to switch)
7, infrared remote control (can control the direction and speed of the car)

This shop car chassis has all the following advantages:

1, high strength, good toughnessAcrylic sheet.

2, the upgrade code, the structure is improved, the accuracy of 10 from the original price, upgrade to 20, so that the accuracy and intensity of the increase in the intensity of the ordinary (non market 6 lines). No longer appear to be damaged when the installation of the phenomenon.

3, the car is used to detect the EMC (eport Europe and the United States), does not interfere with the eternal control circuit of the motor.
Some friends will find, in the smart car when the circuit is designed to connect with the program is right, but it is the sensor to trigger a microcontroller program running is not normal. Check for a long time no results, then I am sure to tell you, your system is the motor brush made out of the spark interference with the EMC detection of DC motor, there will be no interference phenomenon/view/1695664.htmEMC detailed introduction)

4, with a strong magnetic motor, the torque is increased by 2-3 times in the case of constant drive current., the power is full, load 2KG turn freely.

5, each set of cars are independent anti-static packaging, with the 3D Chinese installation drawings are very convenient to install.

6, with inner consistency and elastic wheels(this will not be a concave phenomenon, making the car go smooth)

7, mechanical structure is simple, very convenient installation.

8, the use of four deceleration DC motor turns fleible, directional good, four driven, full power. Chassis large and stable, very easy to epand.

9, the car comes with a speedometer, tachometer with photoelectric shop, you can quickly form a set of measurement system.It can measure speed, distance, form a closed loop system.

10, the car with the shop's L293D dual L298N four motor drive module, the four way to find the track module, there are 51 control unit seamless, leaving the red wall barrier epansion hole, the composition of the system is simple and good looking!

FAQ: why do people's car packages and accessories, like you, the price is more epensive than you most?
SZ: electronic components are the same, make more or less money, basic Taobao are we in the delivery, first-hand sources, in addition to the price advantage, but also the service and quality, providing more than 100 car key information, to help you easily learn on the road!

FAQ: no others home accessories or components, you can find in here?
SZ:5147 components, with the industry the most pro direct use of keyword search, search not to contact treasurer ID!

About motor parameters:
Our default choice 48:1 deceleration ratio, encoder (48:1 strong magnet motor) measured in 7.2V rechargeable battery power supply situation, traveling speed is about 0.65M/S. This speed is good (for most of the smart car applications), of course, increase the drive voltage can increase its speed, the motor operating voltage is recommended, 5-10V.

The car comes with the speedometer: can be used as measurement of the journey, the speed feedback and so on!

Inclined view trolley chassis

Double layer structure: easy to epand

Trolley size and size: the size of the car is two wheel lateral distance 155MM, the length of the car is 260MM

The following picture is only for installation design reference, do not belong to this baby's products

With the store of 51 MCU system, and the two L298N module (you can also shop L293D module a, as shown in the following picture) four DC motor drive module is of no use, four road seeking tracing module and the car chassis with. (can be achieved such as the search for the function such as tracking and obstacle avoidance)

With the store's 51 single-chip microcomputer system, L293D four DC motor drive module, the four path tracing module and the car chassis. (can be achieved such as the search for the function such as tracking and obstacle avoidance)

With the 51 single-chip microcomputer system, Bluetooth wireless module can realize the video phone remote control function

Android mobile phone program

PC end remote control ZK-4WD program

Cant see the car chassis installed (rechargeable battery on the interlayer)

Four way infrared probe installed in the bottom of the car, the distance is very convenient to adjust. The different width of the black line, adjust the probe at the same time, the obstacle avoidance function can close

Can also be used to avoid obstacles probe, avoiding obstacles away from 6CM or so

L293D four drive module, DC head can be directly inserted into the charger. No need to remove the battery (very convenient)

The infrared modulation photoelectric sensor mounting hole, can easily achieve obstacle avoidance function

The steering gear is used to connect the ultrasonic wave for ultrasonic obstacle avoidance.

If you feel that the low chassis can be installed

Maimum price, no one!!Good news, the original price ofEighty-two yuan smart car, now special price ofForty yuan, with strong magnetic over EMCThe detection of the motor,Two0 line speedometer, in strict accordance with the following invoice delivery!
