Tea Bot Solves Another First World Problem

In the movie Wall-E, future humans live in floating chairs and have everything done for them. Today, we grumble if we have to go to physically find a light switch or a remote control. How far away can floating chairs with screens be? T2, the Tea Bot, gets us one step closer to that. Using a laser-cut frame, an ESP8266, and a servo motor, the T2 brews your tea for exactly the right amount of time.

We were kind of hoping the robot would at least dunk the tea bag in and out, but it does provide a web interface that lets you select the brew. Of course, the code is available, so you could make modifications — maybe turn on a hotplate underneath the cup.

While this isn’t particularly practical for most people, it is a nice short example of how to provide a web interface and do something with an ESP8266. Maybe you want to lock a desk drawer or put a marshmallow into a flame, for those tasks you could use very similar code.

Since a servo takes a pulse width and draws very little current, you could probably drive a bunch of them and parallel process a lot of teacups if you were serving a crowd. Naturally, this isn’t the first automated brewer we’ve seen. It isn’t even the only one with a servo.

    >The leaves used in most bags are actually the “dust and fannings” from broken tea leaves. This is a huge compromise in quality from full leaf tea. Finely broken tea leaves have lost most of their essential oils and aroma. When steeped, they release more tannins than whole leaf tea, resulting in bitter astringent brews.

    1. A bot for tea bag won’t magically elevate it to real tea.
      The following URL ere is a serious attempt for tea making bot with 300kg industrial robot – not quite there but it includes pouring techniques. (video included)

      >Built by the Association of Coffee and Tea together with the Hong Kong Productivity Council (HKPC), KamChAI – Cantonese for “golden boy” – is Hong Kong’s first AI tea maker, and has been programmed to brew a drink developed by cha chaan teng, or tea cafes.

  2. Common in Canada’s Maritime provinces. Almost essential.
    Always kept warm. Very tanic.
    But if you have guests, like soup, you just add enough water to have enough for everyone.
