Introduction
As robots are increasingly widely used in various fields nowadays, and the intelligence evolves
rapidly due to deepened innovation in recent years, they have changed greatly, and will continue
to do so, our lifestyle and broadened our view of the world. Robots can work in lots of extreme
and harsh environments where human beings cannot approach. And they can accomplish tasks
easily that we have struggled to do. So is studying robotics more and more popular. To make the
smart car robot work under the best status, it is necessary to learn more about it and seek
improvements in its speed and direction.
This robot is designed for hobbyists to learn about Arduino and robotics. Smart car robots should
first sense an obstacle before avoiding one. The sensor used in this car is an ultrasonic one. The
car detects obstacles via the ultrasonic sensor and avoids them automatically.
This smart car is a typical robot. It's composed of three parts: sensor, actuator, and MCU. Also it
can track lines – sense the leading trace and move accordingly. So the car can recognize routes
automatically, select the right path, and avoid obstacle on the path. The actuator of the car is DC
motors, which control the direction and speed of the car moving. As for MCU, an Arduino board
is used for the core of the car.
This smart car robot is really smart in moving forward/backward and turning left/right in an
unmanned manner by detecting obstacles and determining and controlling the reactions of the
car by the MCU.
In Adeept Remote Control we use ADXL345 Acceleration sensor module, just adjust the tilt Angle
of the remote control we can control the car to go forward, backward, left and right.
NRF24L01 wireless module is also used to transmit ultrasonic data to display on the computer. On
the computer, we wrote an open-source upper computer program using Processing software and
make a simulated radar interface

Functions
The smart car has the following functions:
1. Stick mode: press the button A on remote control, then the LED1 on remote control blinks、
the LED2 lights up and LED3 goes out. At this time the four-wheel car is in stick mode.
Control the two rockers on remote car handle to make the car go forward、backward and
make a turn.
2. Intelligent obstacle avoidance mode: press the button B on remote control, then the LED1 on
remote control blinks、the LED2 goes out and LED3 lights up. At this time the four-wheel car
is in intelligent obstacle avoidance mode. When the ultrasonic module on the car detects
obstacles in front of it, it will automatically control the car to avoid obstacles.
3. Gesture control mode: press the button C on remote control, then the LED1 on remote
control blinks、the LED2 lights up and LED3 lights up. At this time the four-wheel car is in
Gesture control mode, in this model, the ADXL345 acceleration sensor on the remote control
converts the collected information of the tilt Angle of the remote control into forward,
backward and turning information and sends it to the car to control the movement of the car.
4. Wireless radar scanning mode: the specific operation of this mode is to connect the remote
control to the computer, and run Processing program we provide (AdeeptRadarProcessing.
Pde). Press button D on the remote control, and the LED1 on the remote control flashes,
LED2 goes out and LED3 goes out. The four-wheel car is now in wireless radar scanning mode.
Data from distant car can be seen on a computer screen and displayed as a real-time radar
scan.

Remote control:
1. Press the button A, the four-wheel car in the stick mode and the LED1 flashes, LED2 lights
up and LED3 goes out on the remote control. The four-wheel car is in stick mode. The
rocker U1 on the remote control handle pushes the car go forward and backward. The
rocker U2 on the remote control handle pushes the car to turn left and right. The rocker
U2 on the remote control handle pushes up and down to control the car ultrasonic
module to turn left and right.
2. Press the button B on the remote control and the four-wheel car is in intelligent obstacle
avoidance mode. LED1 flashes, LED2 goes out and LED3 lights up on the remote control.
When the ultrasonic module on the car detects obstacles in front of it, it will
automatically control the car to avoid obstacles.
3. Press the button C on the remote control and the four-wheel car is in gesture control
mode. LED1 flashes, LED2 lights up and LED3 lights up on the remote control. In this mode,
the ADXL345 acceleration sensors on the remote control converts the collected
information of the tilt Angle of the remote control into forward, backward and turn
instructions and sends them to the car to control the car's movement.
4. Press the button D on the remote control. The four-wheel car is in wireless radar scanning
mode, the specific operation of this mode is to connect the remote control to the
computer, and run Processing program we provide (AdeeptRadarProcessing. Pde). Press
button D on the remote control, and the LED1 on the remote control flashes, LED2 goes
out and LED3 goes out. The four-wheel car is now in wireless radar scanning mode. Data
from distant car can be seen on a computer screen and displayed as a real-time radar scan.
5. Spin the R1 potentiometer to control the startup speed of the DC motor.
6. Spin the R6 potentiometer to fine tune the direction of the car.
7. The car enters the remote control mode automatically after power on.
8. You can switch the status of the car by the remote control.

Rotate the rocker arm between 0 and 180 degrees.
Assemble the following components
First, learn the structure. The servo can connect the rocker arm and spin to drive components
bound with the arm. There are 3 types of rocker arms and 3 screws in the package. The smallest
screw is to fix the arm onto the servo.
Mount and remove the rocker arm.

Make sure all servos have been adjusted and DO NOT spin the servo shaft before the whole
assembly is done for the car. If you move it accidentally, readjust before the assembly.
Adjust the rocker arm to make it rotate to an almost equal angle towards left and right.
If the angle is not nearly the same, please remove the arm and install it again. Repeat the step until
nearly the SAME degree.
After the adjusting, the rocker arm should be in the middle axis. Remove the arm.

Note: The servo shaft should be closer to
the bulges on the plate, and the nuts
underneath.
