Document what a Tech Day is

Newer teams won't know what these are, plus this gives us a handy
page to reference from the event pages. Not completely sure if this
fits into the Robots 101 section, but it seems as good a place as any.

 As a team supervisor, your role is to guide the competitors through the journey of building a robot. You’ll be there to point them in the right direction when they get stuck and resolve any issues they run into. We encourage team supervisors to limit their involvement with the robot design/building process so that the finished contraptions are 100% student-built which competitors find very rewarding.
 
 You’ll be our point of contact with the team. If you have any questions during the year, just email <{{ site.emails.teams }}>. We’ll also be sending you emails every month or so with important information such as:

+# Robots 101 - Tech Days
+
+Tech Days are opportunities for your team to spend a whole day working on your
+robot, with lots of help available. They’re also an opportunity to see how other
+teams are doing or get more direct help with your robot.
+
+We provide a space for you to work in, with power and internet access, as well
+as volunteers able to help with the kits and hands-on guidance with your robot.
+
+## What to work on
+
+Tech Days typically do not have a fixed set of activities. Instead, what you
+work on during the day is up to you. Some teams use Tech Days as an opportunity
+to generally work on their robot, while others focus on a specific task they
+want to achieve or get help with. You probably do want to have an idea of what
+you'd like to achieve before the day though!
+
+Teams' focus at Tech Days also varies with when the Tech Day falls within the
+competition year. Early on this might mean choosing the components, initial
+robot assembly or completing one of the Challenges. Later on this might mean
+integrating all the sensors & actuators into a fully working robot or finessing
+your robot's interactions with the arena.
+
+## What to bring
+
+Exactly what you should bring to each Tech Day varies by event and where the
+event is hosted, so you should always **check the event page for details**. That
+being said, in most cases you'll want:
+
+* Your _robot_, no matter how many pieces it's in and including any spare parts you have
+* A _laptop with a USB port_ (don't forget the charger)
+* Some _hand-tools_ to work on your kit
+* Your _Team Supervisor_
+
+Some venues may allow you to bring things like _power tools_ and _paint_ or
+_glue_, however not all will. Sometimes you may also need to bring a _packed
+lunch_. Always be sure to check the event pages for details.
+
+## How to attend
+
+Tech Days are listed in the [events calendar][events-calendar] on our website.
+The event page for each one contain details of when & where they are, along with
+anything specific you'll need for the day.
+
+Your Team Supervisor can sign up for your team to attend as many as you like,
+however in cases where events are over-subscribed we will try to ensure that
+everyone has the opportunity to attend at least one Tech Day throughout the
+year.
