Arduino sensors for project

I am student making an unmanned ground vehicle , decided to put temperature and humidity sensor, surveillance camera , ultrasonic motion sensors and robotic arm .I am interested in using sensors that are connected to arduino microcontroller .Can someone tell how do i fix the sensors to arduino on my ugv , what all things I need for installing it , since i am new to arduino

plz give suggestions.....

Get a good frame first of all then
make place for the sensors
then see to it that what mounting facilities like clamps etc are there on the sensors then,
fix them onboard caring for how that sensor works so that hyou dont block its working while mounting some other sensor on its sensing area also lookout for temparature changes on these sensors while they work as it may heat up other in proximity sensors.
