There’s an unwritten rule that everything comes full circle. It’s cool to like 70s vinyl again. Luminescent 80s clothing is back in a big way. Remember Robot Wars on the BBC in the 90s* (where people build robots to battle to the death)? Well, take that, marry it with eSports (think League of Legends), plonk it in a giant Chinese stadium, and you’ve got Robomaster: the world’s first first-person shooter robot battle arena competition.
So how did we arrive here? Well, DJI – the Chinese company better known for its drone products, such as the Phantom – had the brainchild to get students invested in engineering, so provided the tools to make it feasible. The competition is designed as a seven-vs-seven robo-battle to take out the opposing team’s base. But it happens for real, as if eSports escaped the computer and came to life.
It’s popular too. In 2018 the finals had almost one million viewers on Twitch. So to see what all the fuss is about, we popped over to Shenzhen, China, to catch the 2019 finals weekend and get a background education in all things Robomaster. Here’s what it’s all about.
Where can I watch Robomaster?
First thing’s first, you might want to watch for yourself. In 2019 the finals weekend will stream on Twitch – with American, English language hosts – on Sunday 11 August.
DJI’s Robomaster Twitch channel has all the background videos so you can get familiar with the teams, see their creations in detail and watch previous and live matches.
Using augmented reality overlays you’ll be able to see the breakdown of scores and the energy of each robot on the battlefield, to make it easier to see and understand the ins and outs of what’s going on.
What are the robot types and what do they do?
Each team has seven robots: three Standard, one Sentry, one Aerial, one Engineer, and one Hero. The Sentry is automated through pre-programming, the other six are (typically) human controlled from the side of the arena using a PC setup relaying first-person view to its pilot. Many more team members contribute behind the scenes in preparation too.
All bots bar the Engineer can shoot projectiles – the Hero can shoot more damaging ones, which the Engineer can collect – and it’s a case of the team’s pilots targeting the pressure-sensitive pads on each bot’s armour which, when struck, depletes said bot’s health points (HP). Each bot starts with 200HP, but successful attacks can see a level up (lv2 is 400HP, lv3 is 600HP). Sustain too much damage and it’s bot down.
What are the rules?
A match lasts for up to seven minutes. Three of these are used for teams to prepare the arena, clearing any debris or stray projectiles, ensuring bots are reset, charged and ready to go. The next four minutes is when the mayhem ensues, with battle commenced. It’s a best-of-three to win overall (best-of-five for the final itself).
It’s not as simple as it sounds though. Standard bots have 200 projectiles pre-loaded (which remove 10HP per hit), which can be restocked at assigned intervals from within a designated arena area. The Hero doesn’t have any heavyweight projectiles (worth 100HP per hit) unless the Engineer goes to collect them from the central island. This is complicated, however, as the island is raised and different teams will need to develop their own methods to ‘climb’ this structure.
Each base has 2000HP before it’s drained to nil – which is how a team wins before the time runs out. If the clock does reach zero then it’s the team with the most HP remaining that takes the win.
However, a base is shielded from side-on attacks unless that team’s Sentry bot is killed, which sees the shield fall. Aerial attacks are possible, but it takes 100 seconds for the Aerial bot to charge for one minute’s flight time, where it can then go and shoot up to 500 projectiles (also 10HP per hit).
Tactically planning is therefore important. That will change year on year, too, as DJI adapts the arena and changes the goals to create a level playing field for new teams entering the competition – preventing successful previous entrants from repeating their tactics, thus forcing them to rethink their approach. For 2019 that includes a 2x buff activation – so 20HP hits standard, 200HP hits for the Hero – by shooting down a rotating ‘petal’ system to the centre of the play arena in a given sequence (again, challenging teams’ abilities to design bots good enough to do so).
Where does the engineering come into it?
DJI only provides the base Robomaster bots, which teams then develop from. This can happen in a multitude of ways.
There’s programming, where specific bot movements – say to avoid incoming fire – can be developed, such as spinning to make energy depletion less likely as a result of successful projectile hits. The more advanced the team’s skills and the more inventive their ideas, the better chance they’ll create of having the bots to beat.
The Sentry is a prime example: it runs along a rail and is pre-programmed using similar technology to what a self-driving cars use, automatically identifying opponents. If it’s well programmed it can be more adept of aiming, predicting movements, tracking, and defending itself too. Given that the base’s shield defence depends upon the Sentry being operational, it’s a key player in the game.
The other aspect is modifying. Students are able to build upon the base bots to aid their abilities. The Engineer requires this: it can’t access the island unless it has developed a ‘climbing’ method to reach the heavyweight projectiles (they’re golf balls) to pass onto the Hero. It’ll also need methods to collect the crates containing said projectiles and a method to store and pass them over.
The more adept a team is at a variety of abilities – piloting, programming, maintenance, engineering – the greater its scope to win. And being a League of Legends master on the tactical front certainly wouldn’t hurt either.
What’s the prize fund?
The winning team will walk away with 500,000RMB ($75,000/£62,500). Second place is 300,000RMB ($45,000/£37,500). The third place playoff delivers 100,000RMB ($15,000/£12,500). Not bad for paying off that student overdraft.
Keeping in mind, however, that it’s not cheap to enter. That’s why University support is important. DJI will provide one base bot to a team (two to overseas teams), but the rest comes at cost. That can vary from team to team, with the Robomaster Technical Adviser suggesting that figure could vary anywhere from 50,000 to 200,000CNY ($7,500-30,000).
The 2019 competition is the fifth consecutive year that Robomaster has taken place, with over 170 first round team submissions received, from a variety of countries (China, US, Canada, UK, Japan, Hong Kong and Macau). That was whittled down to 122, with 32 teams making it to the final round in Shenzhen (all of which are Chinese).
If all this interests your inner engineer/geek and you want to take part or get your University involved, check out the criteria on the official site. For the rest of us, just enjoy the eSports-to-life mayhem on Twitch. Although, unlike vinyl and 80s attire, we’re not sure everyone will get it.
