Yes, theres lot of ibles about making various robots.

At the very least, it needs a few things:

A chassis - something to hold all the parts together
A method to move - motors, actuators. This can be locomotive, or just stationary - depends on the function.
A brain - It can be smart, or dumb (operated by a user input) or a combination of both. Microcontrollers are a good start.
The robot may do no harm to humans, the robot may do no harm to self, and the robot must act to prevent harm to humans ;)
Sensors so it knows what its doing (depending on the situation) - lasers, photosensors, pressure sensors, encoders for positioning, bump switches, etc etc.
It needs a cute antenna on the top, this IS instructables after all.

There are several Instructables on building robots of varying complexities, from the simplest bristlebot to a fully autonomous Wall-E.

Just type your requirements into the white Search box at the top-right of every page of the site.
