-Up to 3 motors
-1 colour sensor
-a Tablet or Phone with the 'COMMANDER' app installed. 

You must:
Build a robot that can win lots of battles against other robots by knocking them out of a circular arena. 
Your robot must be remote controlled 
Your robot MUST be designed so it can do a 360 degree turn before contacting another robot. 

Tips For students

Tip: The stronger your robot, the better it will survive collisions. You won't win if your wheels or motors fall off!
Tip: Add a third motor to create a weapon. 

TEACHER INFO

Grading option: Often battles depend on a bit of luck, so instead of a knock-out competition it is good to reward kids who are brave enough to battle as soon as they are ready. Make a copy of this Google Sheet to keep track of wins, losses and draws. Students get 1 point for a loss, 2 points for a draw, 3 points for a win. As with all my sheets, you need to go to FILE and MAKE A COPY. Then only fill in the yellow cells.  It's helpful to put a two minute limit on battles. 

Additional Equipment needed.
Sumo wrestling arena. You'll have to make one of these yourself. I just got a large square of chipboard (or MDF) and drew a circle with a pencil and string, (string the length of radius). I then cut the circle with a jig-saw. Ideal size is about 120 cm diameter. The outer white ring should be about 10cm.  Sounds like a lot of work? The one I made has been with me for 10 years! 

SAMPLE  COMMANDER CONTROL

Open App and use arrows to "create and command"

Click on any "+" symbol

Scroll to find and add vertical slider

Place slider on left then click another "+"

Place next to other slider. (Take note of which motor they each control)

Click red SPANNER (bottom right) then connect via bluetooth (bottom left)

Please note, you will have to make sure your bluetooth turned on, on your tablet/phone AND on the EV brick. 

Under the 'spanner' tab make sure the ticks are on for Bluetooth and iPhone/iPad​/iPod
