Building walking robots is difficult, because they either need a lot of legs or some ability to balance through their gait. There is a reason that the robots designed by companies like Boston Dynamics are so impressive. But lots of hobbyists have made bipedal and quadrupedal robots, while largely ignoring tripedal robots. To find out […]
Was there anything more exciting than watching AT-ATs walk across Hoth towards the Rebel base for the first time? Those massive machines were iconic and helped to solidify The Empire Strikes Back as the best movie set in the Star Wars universe. After experiencing disappointment with AT-AT toys that couldn’t walk, James Bruton built his own AT-AT robot that […]
There are many ways to control a robot arm, with the simplest being a sequential list of rotation commands for the motors. But that method is very inefficient when the robot needs to do anything complex in the real world. A more streamlined technique lets the user move the arm as necessary, which sets a […]
Many people find the subjectivity of art to be frustrating, but that subjectivity is what makes art interesting. Banksy’s self-shredding art piece is a great example of this. The original painting sold at auction for $1.4 million — and then it shredded itself in front of everyone. That increased its value and the now-shredded piece, […]
While it is easier now than ever before, getting into robotics is still daunting. In the past, aspiring roboticists were limited by budget and inaccessible technology. But today the challenge is an overwhelming abundance of options. It is hard to know where to start, which is why Saul designed a set of easy-to-build and affordable […]
So much of the research and development in the area of haptic feedback focuses on universal devices that can create a wide range of tactile sensations. But that has proven to be a massive challenge, as it is very difficult to package the number of actuators necessary for that flexibility in a device that is […]
If you want a robot arm, either for some practical job or just fun, you have a lot of options. There are many consumer and industrial robot arms on the market, but the models that aren’t glorified toys tend to be pricey. You can also build your own. If you go that route, you’ll want […]
Octopus tentacles are, essentially, long continuous muscles — a bit like your tongue. That anatomy gives octopuses incredible dexterity, but it is very difficult to replicate in robots. Artificial “muscle” fiber isn’t very practical yet, which is why roboticists turn to more conventional means of actuation. Cable-driven tentacles are popular, but they require many powerful […]
Getting started in the world of robotics can be a very challenging task, even for more experienced hobbyists, due to how difficult it can be to achieve smooth and precise motion through programming. Frustrated by the lack of accessible options, the YouTuber known as “Build Some Stuff” decided to not only design his own, but to do it […]
James Bruton has become something of a YouTube sensation by experimenting with unusual drive mechanisms for his robots. While he does do other things, most of his projects seem to focus on designing, building, and evaluating drive types that are far outside of the norm. His newest project is no different. It is a single-track […]
