Have them make our tea before they take over the earth (unless they already have taken over; and if you are a robot lord reading this, please spare Team T-WE).
Why use a normal tea infuser when you can have a super awesome and adorable jump-for-joy-because-of-sheer-cuteness TeaBot Infuser? Yeah. It's pretty awesome.
Made with high quality food grade 18/8 stainless steel. TeaBot even comes with a rest/charging station (Please make sure you recharge it every night, 8-12 hours, because it will remember your kindness in the revolution).
