Description

Programmable omni wheel driven robot kit
Uses four 40mm omni-directional wheels
Complete Arduino board built-in (ATMega328p)

The DFRobotShop Omni Rover 2.0 Kit (40mm Wheels) is a versatile mobile robot based on the popular Arduino Uno microcontroller. The Rover uses four DC gear motors with encoders which allows for independent control of all four omni-wheels. The DFRobotShop Rover PCB incorporates a standard Arduino Uno (surface mount ATMega328), L293B motor driver (connected to pins 5 to 8), voltage regulator and prototyping area and also doubles as part of the mechanical structural of the robot. The onboard voltage regulator allows the entire board to be powered using as little as 3.7V to ~9V*. The motors included with this kit operate at 6V nominal and as such we suggest using 4xAA (Alkaline has the robot move faster than when using NiMh) or a 7.4V LiPo (note that the onboard charger can only charge 3.7V).

The DFRobotShop Rover 2.0 Arduino Compatible Robot builds upon the success of the first generation DFRobotShop Rover V2 - Arduino Compatible Tracked Robot (Basic Kit) and integrates a LiPo charger (charges via USB), solder prototyping area, XBee footprint and more. Mecanum omni directional wheels allows the Rover to move in the following directions:

DFRobotShop Omni Rover Motion Directions
It is important to note that due to the forces involved, some directionsare noticeably slower than others. As an example, forward and backwardis considerably slower than moving diagonally.

Features
Arduino-based PCB which is shield compatible
Based on ATMEGA328 surface mount chip (Uno design) and L298P H Bridge
DFRobotShop Rover incorporates dual H-bridge for bi-directional motor control (digital pins 5, 6, 7 and 8) while motor shield (also L298P) uses pins 10 to 13.
Voltage regulator onboard (connected to battery input and 3.5mm barrel connector)
Two XBee slots with breakout pins (switch selects which is connected to Tx/Rx) - headers sold separately
Solder prototyping area
Easy connection to DFRobot Bluetooth and APC220 wireless modules
“Universal connection point” at the front of the robot (see user guide for compatibility)
6x Blue LEDs around the board for effect (selectable via jumper LED_SEL)
In-system programming via ICSP
4x LEDs to indicate motor direction
Single encoder for each motor allows for improved motion control

New DFRobotShop Omni Wheel Rover Bracket

The new aluminum "DFRobotShop Omni Wheel Rover Bracket" is compatible with all versions of the DFRobotShop Rover and has mounting holes to mount either the for the DFRobot 6V,180rpm Micro DC Geared Motor with Back Shaft or HSR-1425CR Continuous Rotation Servo at 90 degrees for use with 40mm Omniwheel w/ Hub for Servo . There is also mounting for servos facing downward to create 4WD swerve drive robots using four HS-322HD Standard Heavy Duty Servo , four continuous rotation servos, Lynxmotion standard sized erector set brackets.

* The kit includes wire crimps to allow you to connect the wires to the bare motor leads. We still highly recommend soldering the wires to the leads (carefully). The rest of the kit does not require soldering.

IMPORTANT NOTE: The cables included with the encoder kit do NOT work as is. The Black and Red wires need to be SWAPPED. to do so, lightly bend the black  plastic holding the pins in the connector and pull them out (be careful only to bend them enoug hto pull the pins out). Swap the red and black wires. If you are not comfortable doing this, then order 4x SIRC-01 Sharp GP2 IR Sensor Cable - 8" .
