In this step, University of Reading graduate, Rory Mangles, writes about another robot application – Robot battles! You can read all about the events below and also follow the links to watch the robots in action.

In the early 2000s, the BBC hosted a cult children’s television series Robot Wars. The premise of the show was to have robots – designed by amateur and professional roboteers – fight to the death! As you can imagine, it was an instant hit.

Robot Battles Continue

After the original series went off the air, you might have thought that would be the end of it. However the roboteers still had their robots and weren’t going to give up that easily! So various live shows and events have been held every year since, with new robots being built and technologies improving. These days, highly engineered and incredibly powerful machines fight it out across the country. It is thus not surprising that the show is back on again!

Robot Battles Premise

The basic premise of the sport is that two or more remote controlled robots have 3 minutes in an arena to disable their opponents by either getting them in the pit, out of the arena, or by destroying them. If more than one is still mobile, then the decision goes to the judges. They decide who wins based on style, control, damage and aggression.

Robot Battle Classes

There are several different weight classes which fight in the UK:
  • Heavyweight: 100kg
  • Featherweight: 13.6Kg
  • Beetleweight: 1.5kg
  • Antweight: 150g
  • Fleaweight: 75g
  • Nanoweight: 25g
The Beetle, Feather, and Heavyweight robots battle it out at live shows around the country roughly twice a month in front of a crowd of around 500 people, with championships held for each weight class once a year.
The Antweights and below meet up 3 times a year for the Antweight World Series. Over 150 robots competed when it was hosted at the University of Reading. The Antweight class is the more beginner friendly of the categories, attracting roboteers of all ages.
There are loads of different designs of robots, from simple pushers and grabbers, to powerful C02 powered flippers and high speed spinning disks. All of them designed to take out their opponent as effectively as possible, whilst not getting destroyed.
The University of Reading has had a long history with the ‘sport’, with robots from the University featuring in the original TV series.

Building a Battle Robot

So how much time and effort goes into building a fighting robot? It can be surprisingly little once you know what you’re doing. The main components needed are motors, wheels, motor controllers, radio receiver, weapon, and chassis. For antweights, almost all these parts can be bought as pre-made kits from the Robot Wars Group, or from other sources on the Internet.

There are also great online communities who are happy to help source parts and provide advice. It’s a great way to get into engineering, and many of the roboteers have gone on to get jobs in the area.

Robots or Machines?

It is worth noting that while these are robots in some ways, they are remotely controlled machines, and are somewhat different from the robots you will meet in the simulations on this course.
