Two robots enter and one robot leaves! Battle robots are an excellent display of design and skills, but mechanical competitors need not be large, heavy or expensive. There is a counterweight department for combat robots. Most of the participants weigh only 150 grams, and [Harry made things] shows four participants participating in the world series of counterweights (AWS) 64.
Each of them has a very different design, a large number of photos, and deep details about what they do and how they work. This is exactly the details we like to read. Thank you very much [Harry] for sharing!
In battle robot technology, competitors usually manipulate remote-controlled machines to lock or fix opponents. This may be because they are damaged and stop working, but it may also be because they become helpless by taking advantage of some mechanical advantage.
One of the robots is tracked, two are wheeled, and the fourth is a walker. The Yellow loader is a crawler type design in the form of a low, flat wedge with a central lift arm. The idea is to lift them from under their opponents. Ideally, let their wheels off the ground and eliminate their mobility. Another design is sad Ken, which uses a horizontally rotating rod as a weapon to give the opponent a good “old” blow. The green goblet has a front mounted aluminum “stirrer” directly mounted on a brushless motor, similar to a combine or thresher. The last design is shakma, a cam based walker that slowly hobbles along while dramatically rotating a funny big saw blade.
As one might imagine, 3D printers have made great contributions to combat robots in general. [Harry] his favorite method is to print the robot’s body into a large piece of strong abdominal muscles, with a corner on it that can accommodate all the parts that need to work. There are a lot of cross pollination in the RC aircraft world. Brushless motors, radio hardware and ESC (electronic speed control) are common scenes. But this does not mean that people have not broken the limit. Fans use raspberry PI zero and Bluetooth game controller to replace RC devices, and carbon fiber is usually used to reduce weight.
Watch the video (shown below), visit the 150g heavy loader, and view other views of the hardware and design. Maybe you will leave with your own inspiration?
