Step 1) Install Cooper standoff on the chassis
If your motors have already connected with a copper standoff, please skip this step and directly go to Step 2
Follow the picture below to install 4 copper standoff on the positions of the blue lines first, then fasten the 4 motors onto the 4 standoffs. Make sure the motor directions must be correct(exactly same as picture)!

Step 2) If you have already installed motor and standoff in Step 1, please skip this step and go to Step 3
If your motor comes with pre-installed standoff, please follow the pictures below to install them onto the chassis.
The four motors have two types of standoff positions:
Type A have standoffs installed on the RED wire side of the motor (see picture 5 top two motors)
Group B have standoffs installed on the Black wire side of the motors(see picture 5 lower two motors)
Picture 5: distinguish two type of motors

Step 3) Connect wheels to the motors
The Mecanum wheel has some sub-wheels on the main wheel. The four Mecanum wheels have two types by the sub-wheel directions. Check the type A wheel and type Wheel by following picture 8 left side . You must 100% sure that correct type of wheel is installed into correct position as per picture 8 right side, the rolling direction of each wheel will determine the whole car moving directions showed in the picture.

Picture 9: different rotation combination of 4 wheels will result in different car movement directions. Following pictures shows how they works.
Step 4) Install Mega2560, Model X boards(L298N), Wifi shield onto the chassis

Picture 12: Wifi shield installation guide
When insert/remove the 6-pin parallel cable plug into Model X 6-pin male socket, please hold the black plastic pin-holder to do operation. Never drag the wires to pull the plug out of the socket, otherwise it will damage the wires.

Note: wire(purple wire) is connected to D22 which is located on the SECOND female hole from right in following picture 10. Many people treat the first hole as D22. THIS IS WRONG.
