ElegooCar

Software for my ELEGOO Smart Robot Car Kit V3.0 and V4.0

The idea of the project is to have an object-oriented solution to control the car, and to have all features in one implementation.

Feature	Car Version	Status
Bluetooth remote controlled	V3.0 only	Implemented
Infrared remote controlled	V3.0, V4.0	Implemented
Switching driving algorithm via bluetooth remote control	V3.0 only	Implemented
Switching driving algorithm via mode switch button	V4.0	Implemented. Toggling through available drivers.
RGB LED shows selected driving algorithm	V4.0	Implemented
Manual mode 1 (Manual-1), brakes on obstacles	V3.0, V4.0	Implemented. Only moves a short distance at a time
Manual mode 2 (Manual-2), brakes on obstacles	V3.0, V4.0	Implemented. Keeps on moving until it gets stopped
Automatic mode 1 (Auto-1), continuous driving with obstacle avoidance	V3.0, V4.0	Implemented. Has trouble recognizing soft obstacles, smaller obstacles, and walls if approached in angles < 45 degrees or > 135 degrees
Automatic mode 2 (Auto-2), interrupted driving with rescan of environment	V3.0, V4.0	Implemented. Has trouble recognizing soft obstacles, smaller obstacles, and walls if approached in angles < 45 degrees or > 135 degrees
Line tracking support	V3.0, V4.0	Planned
More hardware suppport (MPU6050, WIFI Control)	V4.0	Planned

The Car

IDE

Developing using the Sloeber IDE (for Windows) "Download 64 bits Bundle" from http://eclipse.baeyens.it/stable.php?OS=Windows

Libraries

Using following libraries:

Library	Version	Location
Servo	1.1.7	https://www.arduinolibraries.info/libraries/servo
IRremote	2.8.0	http://www.arduinolibraries.info/libraries/i-rremote
FastLED	3.4.0	https://www.arduinolibraries.info/libraries/fast-led

Verify and Upload using the Arduino IDE

This software can also be used in combination with the regular Arduino IDE, as documented below:

Step	Details
Download and install the Arduino IDE	Download from https://www.arduino.cc/en/Main/Software and follow the provided instructions
Download and unpack the ElegooCarV3 package	Download https://github.com/pieterbl/ElegooCarV3/archive/master.zip and unpack in your Arduino sketches directory, so that you have a directory ElegooCarV3 with the files ElegooCarV3.ino and the remaining files in it
Download and install the latest IRremote library version	Follow the Installation instructions here https://github.com/z3t0/Arduino-IRremote/blob/master/README.md and make sure to follow the instructions regarding the RobotIRremote library. Download of version 2.2.3 is accessible here, too http://www.arduinolibraries.info/libraries/i-rremote
Restart the Arduino IDE and open ElegooCarV3.ino	Check and modify the CAR_VERSION in ElegooCarV3.ino. Make sure your car is connected with your computer. Press verify to verify the software, press upload to upload the software to the car
Download and configure the bluetooth app	Download the bluetooth app from the below given locations. Configure the bluetooth app as described below
Drive the car	Have fun and enjoy it

Driving the Car

This is how driving the car looks like https://github.com/pieterbl/ElegooCarV3/blob/master/ElegooCarV3.ino

Driving with Bluetooth

The bluetooth app can be found at the below listed locations:

Provider	Location
Google, Andriod	https://play.google.com/store/apps/details?id=com.femtoapp.rootsence.bleutils
Apple, iPhone	https://itunes.apple.com/gb/app/elegoo-ble-tool/id1195318538

The bluetooth app must be configured in the following way:

Left Column	Middle Column	Right Column
Half Left (\)	Forward (F)	Half Right (/)
Left (L)	Stop (S)	Right (R)
Manual-1 (M)	Backward (B)	Auto-1 (1)
Manual-2 (N)	empty	Auto-2 (2)

Driving with Infrared

The Car is shipped with a infrared control.

Key	Action
Arrow Up	drive forward
Arrow Down	drive backward
Arrow Left	rotate left
Arrow Right	rotate right
*	switch to next driving mode

Trouble Shooting

avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

Lots of articles on this in the Internet. For me, it means the bluetooth receiver must be removed from the car. It is preventing the upload of a new program version to the Arduino.
