Mars Explorer Mecanum Wheel Robotic Kit
(Arduino Mega2560)
More information: http://osoyoo.com/?p= 30176
Mecanum wheels, also known as omni wheels or Ilon wheels, consist of a hub with rollers oriented 45°to the
axis of rotation.The mecanum wheels are wheel hubs fitted with integrated rollers that move passively and
independently.
Depending on which wheels rotate in which direction, the platform will move forward, backward, sideways,
diagonally, or spin in place. This range of maneuverability enables the Omni Platform to efficiently navigate
any space, particularly around tight corners, narrow lanes, and complex pathways.
This Arduino Omini Direction Robot Car learning kit is developed our Japan and Canada engineer team. It
has all features a traditional Arduino Robot car should have, including remote control by Bluetooth, IoT
through Wifi, Line tracking and Obstacle Avoidance auto driving. With the help of powerful Mecanum wheels,
the car can make much more complicated movement such as sideway shifting and digaonally movement
controlled by Cell phone APP.
The kit comes with OSOYOO MEGA2560 board(fully compatiable with Arduino MEGA2560) and
OSOYOO ESP8266 Wifi Shield. Besides, we have designed five step by step lessons which help students to
learn Arduino robot programming from scratch. If you are an experience DIY player or Arduino programmer,
you can also get a lot of knowledge from this kit’s open source code and hardware to make interesting DIY
project of your own.

Lesson1 Assembling the Car
Mecanum Omni direction wheel is a very interesting wheel which allows robot car make
omni-directional movement( parallel shift to left and right).
In this project, we will show how to use Arduino to control an Osoyoo Brand Mecanum wheel
robot car to make some basic movement including go forward, backward, left turn, right
turn, parallel left shift, parallel right shift etc.
This lesson also shows you how to install the chassis of this car and connect Arduino
control signal wires to two model-X (L298N) driver board. This installation will be the
start point of our other lessons.

Picture 2: Chassis screw location map (view from top)
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)!
Picture 3: Motor fasten screws location map (view from bottom of the chassis)
Picture 4: Motor installation guide map
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.
Picture 6: Type A and Type B motors location map in chassis.
Picture 7: Wheel installation map
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 8: Two types of Mecanum wheel and their installation position in the car
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
