Approximately:
Theft = unlawfully appropriates property with intent to deprive the owner of property
Robbery = Theft + causes bodily injury to another OR threatens or places another in fear of imminent bodily injury or death
Aggravated Robbery = Robbery + causes serious bodily injury to another OR uses/exhibits deadly weapon OR causes/threatens bodily injury to 65Yo+ or disabled person
The value of the object unlawfully appropriated does not determine whether an act is theft, robbery, or aggravated robbery but it can influence the seriousness of the crime and its punishment.
This is a pretty good explanation of the difference between theft and robbery.
Understanding theft offenses is a trick in itself though. Theft now includes receiving property you know to be stolen and a few similar charges that are variations of someone got something without the owner's knowing permission. The first rule is that the value determines the grade of offense, from class C misdemeanor to 1st degree felony. There are some upgrades for specific items being stolen though, such as livestock or firearms. There is an upgrade many became familiar with just from this incident if the theft is directly from a person (as in on the person). There are upgrades if you have previous convictions for theft. There are upgrades if the victim is elderly or if the theif got the material stolen as a result of his being a government employee.
There is a second section that is a little easier to understand but is still different. If the theft is of a service (think not paying for a mechanic's work or something similar). This is covered in section 31.04 instead of the regular theft in 31.03.
As an aside, if they steal a car, most criminals get charged under 31.07 for unauthorized use of a motor vehicle instead. This is because of the intent required (prove keep the vehicle) for theft. A lot of the car thieves are going [abbreviated profanity deleted] joy rides and do not intend to deprive the owner permanently.
For an area that most people can understand the basics of very quickly, theft is a very complicated subject in Texas when you get into the details. Reading the law posted at the link posted above is a very good start. The whole chapter can get very confusing very fast, especially with imaginative application of the exact wording of the law.
