Robotics

Sims can use the Robot Crafting Station to build robots.

No badge
Toy Robot - a basic toy robot. It doesn't have any special qualities whatsoever and acts like a normal toy. Sims with low mechanical skill will have a higher chance of making a Toy Robot in poor condition. The Toy Robot comes in three different colours and can be named when a Sim starts making one.

Bronze
A Sim will attain the Bronze Robotic Talent Badge after quite a bit of time making Toy Robots. By acquiring the Bronze badge, Toy Robots are made faster and a new type of robots, called Roverbots, are available to build.

Clean Bot - Basically a robot that cleans up the lot it is activated in. The major shortcoming of this robot is that it only can clean up items that are on the floor. In other words, it can't clean counters or showers or sinks, nor can it dispose of anything that's on a surface. However, it can empty trash cans. When broken, it makes a larger mess for you to clean up.

Hydro Bot - A robot that puts out fires or waters your plants. When broken, it will create puddles of water everywhere.

Silver
Acquiring the Silver Robotics Talent Badge gives Sims the ability to create Toy Robots and Roverbots at a faster pace. It also gives Sims access to the new Hoverbots.

Sentry Bot - An all in one policeman robot. It will shock shoplifters and robbers when it gets the chance. It will also shock newspaper stealers and garbage can tippers. Placed on a college residential lot, it will shock the Cow Mascot. However, it appears to ignore wolves and stray pets who do things like tip the garbage can or roll in the flowerbeds. When broken, it will shock random people.

Munchie Bot - A robot that will fetch food from off your lot when your sim is hungry. The meal will be paid for by yourself of course. When broken, it will bring back rotten or burnt food for your Sim.

Gold
The last and final badge. Make Toy Robots, Roverbots and Hoverbots extremely fast. It also opens up the option to build an old friend from The Sims: Servo.

Positive effect
Sims with high mechanical skill possibly get experience faster.

Negative effect
Sims with a low mechanical skill will have an increased chance of making robots that need to be repaired.

With a new understanding of how wheels, motors and computer chips go together, NAME can now build "RoverBots" to do some basic chores around the place! That's worth the Bronze Robotics Talent Badge!

Silver

Wheels are very fine, but mastering hover technology has let NAME make "Hover bots" that can keep a sim safe as well as fed. That deserved a silver Robotics Talent Badge
