RoboDojo 27/07/24

Image
 We took all three of our robots to York for our second RoboDojo event.  Exposure Exposure's first fight was against Percussive Maintenance XL. As the fight started, I got a good hit and flipped him over, however the belt once again snapped. This left me to be bullied around the arena for the rest of the match and the judges decision obviously went to PMXL. We rejoined the belt for hopefully the last time, and waited for the second fight. The second fight was a rematch against Little Grey Fergie. The fight started with me getting a good hit, then another, the another! The belt stayed on for the entire fight! I did have a bit of a scare when one of my wheel guard screws came loose and high-centred me, but I just managed to wiggle free and give a few more big hits before my opponent tapped out. The third fight was another rematch against Chucky, and like last time, I was bullied around the arena and pitted. However I was very happy that the robot managed to self right on the wea...

Extreme Robots Newcastle

Image
 This weekend we traveled down to Newcastle so my dad and I could help out at the Extreme Robots shows. This was such an amazing chance to meet the builders and learn how events like this work. My job for the three shows over the weekend was to help Dave Weston run the antweight arena, which was a lot of fun, and I was driving one of robots for a lot of time, so it was great to practice my driving skills with more control-based robots in the antweight class. We met lots of very nice people who were more than happy to talk about their robots, and give advice for our own robots. I was also interviewed for Extreme Robots TV!  It was amazing to see all three shows and be able to go backstage and see damage up close. Special thanks to John Findlay for allowing us to come and help out!

Antweights

Image
Because the Robodojo events have an antweight competition along with the beetleweights, we decided to make a couple of ants to take to the next event. These follow the same theme and colours as Exposure, but are a little less competitive and more of a chance to try new things and make robots that are fun to fight.  However, I still wanted to make a spinner. So I thought for a long time about how I could make a spinner that would be entertaining, but not too serious, and I eventually settled on a 4WD large undercutter design. The plan was to make the chassis as small as possible but make the weapon as LARGE as possible. The actual chassis footprint is only about 80 x 65mm! This was printed in PLA+ with 2 walls and 30% infill, which feels nice and strong. It also runs on 3S LiPo because why not, and uses a 2700KV 1806 motor to power the weapon. This gives a theoretical tip speed of 319mph, or 34,000 rpm with the largest weapon. Also, due to the battery voltage, we couldn't use the ty...
