We have seen many impressive robots of various sizes on Hackaday, but we have been particularly inspired recently [Hans Jørgen Grimstad] And his thrift Mini sumo.
Starting from the BBC micro:bit platform, Hans seized the opportunity to create a competitive mini sumo robot without going bankrupt. According to his blog, this charming little machine uses common parts and will cost about $30 when it is manufactured in 2020 (according to a recent video, the cost is $50, perhaps taking into account the hardware costs of these difficult times).
The result can be seen in the video below. Made some sacrifices-Hans admitted that the 3.3 V linear regulator was a bit outdated, but by eliminating the switching regulator, the design became simpler. The 700 RPM N20 motor is directly connected to the 6 V battery pack to provide this brave wrestler with sufficient sumo ability.
Hans hopes that this construction can lower the barriers to entry for new builders in the Robotics Championship, because it can be easily assembled in a garage or local maker space at a low price.The mini sumo shape is a good beginner or amateur project, it becomes easier when a manufacturer like Hans Put all the details on GitHubThis is certainly not the first accessible sumo robot project we introduced, and it will not be the last. We hope we can see more of these cute robot gladiators in future events.
