    Robo Challenge
    , builders of the new house robots for Robot Wars using R-Tech Welders have built a robot to compete over in China's King of Bots series. Here is the first of their behind the scene's video of the journey. We look forward to seeing more of the build and the engineering that goes into making this battle robot.

    King Of Bots continues today in China. Over the course of the competition we hope to bring you this little documentary series charting the build from the first clicks in CAD to the very first fight and all the fun in between. If you like engineering, robots, and tight deadlines this is the mini-series for you!

    R-Tech Welding Equipment Meets Robo Challenge

    net-and-ben-with-house-robotsRobo Challenge invited us to come and meet the team and the house robots ahead of filming for the second series of Robot Wars. We spent the morning chatting with the Robo Challenge team and having a look around their workshop.

    The family run company is based in Birmingham and make one-off creations for a number of media clients. Recent projects include a working replica of a gun from ‘Titanfall 2’ video game and a full size Mack (robot dog) from the game ReCore. Robo Challenge use a range of technologies during the build including robotics, welding, plasma cutting and 3D printing. There were over 1,000 hours of 3D printing to make Mack!

    The BBC asked Robo Challenge to create the house robots for the re-launch of Robot Wars which aired earlier this year. Robo Challenge also designed the new battle arena to accommodate the new bigger, badder robots.

    Robo Challenge and a number of the teams that compete in the Wars use R-Tech Welding TIG’s, MIG’s and plasma cutters to create their robots.

    R-Tech Welding Interview Robo Challenge about House Robots for new Robot Wars Series

    R-Tech Welding caught up with Robo Challenge to discuss the building of the updated house robots for the up-coming new series of Robot Wars. Robo Challenge purchased an R-Tech MIG180, MIG250 and TIG210EXT to construct these huge robots.

    Q - It has been 12 years since the last series of Robot Wars was filmed. What upgrades have you given the house robots to keep up with the changes in technology?

    In the last 12 years, technology and materials have improved significantly. These include ultra-lightweight and powerful Lithium Polymer batteries giving increased performance and more spare weight to dedicate to weapons and armour. Motor technology has improved significantly in the recent years with small lightweight and powerful brush-less motors, these can be up to 10x lighter than older brushed motor technology.

    With this in mind we knew the House Robots needed more drive power, more weapon power, more armour and also a lot more weight behind them. The drive on Matilda and Shunt are around 12x the power of their predecessors.

    Shunts axe is immensely more powerful than it used to be, running at higher CO2 pressures and a much larger weapon overall. Every single element of each robot has been improved to take on the ever increasing power of the competitors.


    Q - How did Robo Challenge get involved with Robot Wars?

    Robo Challenge are contacted regularly with regards to creative engineering projects for TV shows and PR campaigns. Our reputation of high quality work, fast turn arounds and friendly family run business means we are the go-to company for a lot of exciting projects such as this.

    Q - What metals are the robots made from?
