the first thing you should do is to separate the motor supply.It will consume a lot of power.When i was designing the same but using 434 MHz rf modules due to negative peaks produced by motor there ware fluctuations in the circuit and moreover the motor will consume most of the power and hence degrading the module functionality.Also you have not to connect the GNDS of both power supply as it will transfer the back emf to uc & rf module.Option is either you connect diodes,capacitors across motor or use optoisolator as connection between motor driver ic and uc.

Subject: [booksbybibin,www.booksbybibin.tk] Xbee , motor controller and control circuit

I am designing a wireless remote control robot. The goal of the
project is to send a wireless signal to a robot which will intern
give left,right,forward, backward and speed control to the bot.
There are going to be two robots that are going to be control. The
first( alpha) is going to control the second robot.So the second bot
is a duplicate of the second.
Here is my question: I am going to have a Xbee wireless module, motor
control and control circuit. what will be a good advice for power
distribution. should I give each or two module a separate power
question arise because I am designing a PCB board and is considering
to run the motor controller, control circuit and the X bee all built
on the same board. so power sharing and distribution( power rating for
each module is different). I have two chargeable 7.2 v 7400mAH
Here are my power sharing ideas: Xbee and control circuit on same
power supply. Motor controller on a separate motor controller
