Pir sensor & Rf module conflict at robot

Using Arduino Sensors

Hello! I'm trying to make a robot which moves from one way to another and when it finds something in its way then it rotates, it also has the capability to sense of human presence and when someone passes it can send radio signal to a receiver which is in another location, everything seems to work fine but I have this problem, when I grab the motor in my hand and make it a small move, it senses of a human presence and it sends signal, even if the pir sensor can't "see" me. I know it has to do with the pir sensor because when I remove it everything works fine, I am assuming is something to do with noise but i've tried all types of filters with resistors and caps but nothing happened. Since i'm not a software expert could someone have a look at the code and suggest something?

The PIR-sensor observes that the "temperature picture" changes when you move the sensor.
Some sensors have the possibility to change sensivity..

Hello, I've adjusted the potentiometer which is for the sensitilivy, I even changed the jumper of H / L but nothing happened, do you have any other way of modification in mind?

What about a ping sensor to see obstacles?
The PIR sensor cannot tell what is moving - itself of something in view.

I don't think a ping sensor is the solution, I think a code in the software which can separate the presence of a human being than a quick movement of the pir sensor is, the problem is that I don't have the knowledge to write this kind of code.
