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 supplies?
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 batteries.
Here are my power sharing ideas: Xbee and control circuit on same power supply. Motor controller on a separate motor controller
