Trait chips are a feature of The Sims 3: Into the Future. Trait chips are a trait system that is only used by Plumbots, and which replaces the trait system used by Sims. There are 21 trait chips available in the game.
Each trait chip is placed into one of four hidden categories: ability, skill, service, and social. Different trait chips have different effects on Plumbots. Plumbots may have 3 to 7 slots depending on their quality level, and can be upgraded to have more trait chip slots. Slots can be left empty, and trait chips can be removed and replaced at any time, though there is a chance that removing a trait chip will damage it.
Sims are able to buy trait chips from the bot emporium in Oasis Landing. Designing a trait chip increases the Bot Building skill. Sims can also buy the Trait Chip Bundle for 10,000 lifetime happiness points.
Sims can also design and create trait chips with Reventlov's Bot Workshop. Designing a trait chip increases the Bot Building skill. Creating a trait chips requires a certain level of Bot Building skill as well as the components needed to create it. The needed components may include any nanite, specific nanites, blank processors, and crystal flowers.
