Products Description
Parameter Table
Light load speed: 1.0m/s Turning radius: 0m Floor material: 4.5mm acrylic and 3mm aluminum alloy are optional (the trolley without suspension uses acrylic bottom plate, which is slightly soft to make the wheels slightly adaptive. The reason why the trolley without suspension cannot use aluminum alloy is that if the rigid board of aluminum alloy is used, the surface of three points will be formed, and inevitably one wheel will be suspended. The trolley running effect is very bad.)

Product features
1. Provide kinematic analysis to solve the input target velocity 2. Provide speed double PID control 3. Support Android mobile APP remote control 4. CAN bus control is supported 5. Support serial port control 6. Equipped with attitude sensor MPU6050 7. CAN and serial port are supported to collect data of the car encoder and gyroscope 8. Secondary development, provide the underlying source code and schematic diagram\

The motion effect of the car is shown in the demonstration video. When the car is steering, all four tires rotate around a central point approximately to ensure the driving stability. However, since the car has no steering mechanism in four-wheel differential steering, it is difficult to guarantee this, and it is easy to slip with the ground when the car is steering. Therefore, the actual motion effect depends on the control algorithm and the external environment. Note: the above function introduction is based on STM32 version. Due to the poor master control performance of Arduino version, it does not have the fourth, fifth and seventh functions. The overall operation effect is also worse than that of STM32 version, and it is not equipped with CAN interface.
Support APP remote control
APP remote control is supported by bluetooth module, and the status of the car can be displayed and parameters can be set on the APP

Support PS2 controller remote control The motherboard reserves the socket of the PS2 handle receiver,which can be used to control the speed and steering. The speed can be stepless adjusted through the rocker
Support linear CCD line (STM32 version only)

Support linear CCD line, provide relevant code.
After you have built a good track to complete the line
Support electromagnetic line patrol
          (STM32 version only)
Provide the relevant code, compatible with the NXP smart
car track (but not including the right Angle of the
complex track), after the completion of the laying of the track to complete the circuit

Standard with common axis 
pendulous suspension system
Because three points form a surface, if the bottom plate is rigid, the four-wheel car has an unavoidable problem, easy to appear wheel suspension, can not be adjusted normally,not to mention indoor navigation, automatic driving. Our car is equipped with aluminum alloy bottom plate under the premise, equipped with a coaxial pendant suspension system, can adapt to uneven ground. .
B3 lithium balance charger
It is designed for completely independent 3-way charging chip management, with its own switching power supply, no extra adapter, which can effectively protect the battery and prolong the battery life. It is only suitable for charging 2s-3s (7.4v and 11.1v lithium batteries).
Original data of upper computer In the form of waveform and graphics to monitor all the parameters, is the PID, balance car, inverted pendulum, robot and other in-depth analysis of the ideal choice, all the data can be saved in the form of text or form, sent to Matlab and other software for further analysis!
New launch of bluetooth &WiFi version of the APP
1. Support gravity induction remote control and two-handed button remote control mode. 2. Supports 5-channel waveform display interface, and can view waveform at any time without data line. 3. Support 9-channel parameter adjustment interface, support online PID parameter adjustment and power off storage. 4. Optimize the alarm mechanism of electric quantity, and the APP accurately pushes the low-voltage alarm notification to avoid overdischarge of the battery. 5. Support bluetooth 4.0 module for BLE. 6. Support the latest version of Android.
