Package List
Hardware installation
Install devices
Step 1. Install the gear motor holder on 1st layer car chassis(metal) with M3*10 screws and M3 nuts as following pictures.
Step 2. Install 2pcs 520 gear motors with cable on gear motor holders which stand at the front of chassis and 2pcs 520 motor with encode on gear motor holders which stand at the back of chassis with M3*8 screws.
Note: Please keep 4 axis of motors at the same level
Step 3. Install the jack screws on Al-alloy coupling, please tighten jack screws to fix the Al-alloy coupling on motor as following pictures.
Note: The axis of 520 gear motor has a plain side. Make sure that one of jackscrews is positioned at this flat, and tighten both jackscrews on the axis.
Step 4. Install the 4 Mecanum wheels on al-alloy coupling with 4pcs M2.5*20 as following pictures:
Note: There are two types of Mecanum wheels, left and right Mecanum wheel; the difference between them is the orientation of rollers. A correct configuration requires each of four wheels is set in the way as shown below, where the rotation axis of each wheel’s top roller points to the center of the platform. Please notice that all the dynamic analysis and pre-written codes are based on this configuration.
Step 5. Install 12pcs M2.5 plastic pillars and nuts on 2nd layer car chassis (Acrylic) and then fix 3 in 1 power adapter, voltage meter, OSOYOO control board for Mega2560, and OSOYOO Model Y motor driver module with M2.5 plastic screws as following pictures:
Step 6. Install battery box on 2nd layer car chassis with 4pcs M3x10 screws and nuts as following pictures.
Step 7. Remove two jumper caps from OSOYOO Wi-Fi shield and insert it into OSOYOO Control board for Mega2560 as the following pictures.
Connections
0. Before connect wires, make sure you have inserted OSOYOO Wi-Fi Shield onto control board for mega already and remove the red jumper cap.
1. Connect 4 motors to model Y driver board as the following pictures.
2. M_A ENA, IN1, IN2, IN3, IN4, ENB of model Y connect to D11, D5, D6, D7, D8, D12 of Wifi shield.
M-B ENA, ENB of model Y connect to D9, D10 of WIfi shield, and M_B IN1,IN2,IN3,IN4 of model Y connect to D22,D24,D26,D28 of OSOYOO control board of Mega2560.
Caution:
When insert/remove the 6-pin parallel cable plug into Model Y 6-pin male socket, please hold the white plastic pin-holder to do operation. Never drag the wires to pull the plug out of the socket, otherwise it will damage the wires.
3. Connect voltage meter to model Y motor driver board with 3pin female to 3pin female jumper wire; connect V_OUT socket of OSOYOO WIFI shield to VIN socket of Model Y motor driver board with 2pin to 2pin jumper wire (female to female); insert 2pin plug(s) of battery case(s) into 3in1 power adapter; insert 2pin plug of 3in1 power adapter into V_IN socket of OSOYOO WIFI shield as following:
Note: 3in1 power adapter is for multi battery case with the same voltage.
4. Install 2nd layer car chassis on 1st layer car chassis with M3*40 pillars. Please note the front and back of acrylic chassis and metal chassis. The robot car can work when completing this step
5. If you want to add more sensor, you can install 3rd layer car chassis on the robot car. Tightly screw M3*40 copper pillar with M3*65+6 copper pillar to be long pillar firstly, then Install 3rd layer car chassis on 1st layer car chassis with these long pillars
Sample project
Step 1: Install latest Arduino IDE (If you have Arduino IDE version after 1.1.16, please skip this step). Download Arduino IDE from https://www.arduino.cc/en/Main/Software?setlang=en, then install the software.
Step 2: Download https://osoyoo.com/driver/mecanum_metal_chassis_m2/m2-lesson1.zip, unzip the download zip file called m2-lesson1.zip, you will see a folder called m2-lesson1.
Step 3: Connect Mega2560 board to PC with USB cable, Open Arduino IDE → click file → click Open → choose code “lesson1.ino” in lesson1 folder, load the code into Arduino.
Step 4: Choose corresponding board/port for your project, upload the sketch to the board.
Disconnect Arduino from PC, put battery into battery box. Put the car on the ground, and turn on the switch on OSOYOO Uart Wi-Fi shield and the switch on battery box.
The car will move
Forward→Backward→Left turn→Right turn→Right Parallel Shift→Left Parallel Shift→Up Right Diagonal→Down Left Diagonal→Up Left Diagonal → Down Right Diagonal
