Robotics is already an intimidating field, thanks to the complexity involved. And the cost of parts, such as actuators, only increases that feeling of inaccessibility. But as FABRI Creator shows in their most recent video, you can build a useful robotic arm with just a handful of inexpensive components. This is pint-sized robotic arm that […]
If you have an interest in robotics, then a robot arm is a great educational tool to start your journey. But professional robot arms are expensive and the DIY route is more informative anyway. That’s especially true if you take the time to design the arm yourself, as did Oliver Paff after he got himself […]
Started in 2022 as an exploration of what’s possible in the field of DIY robotics, Pavel Surynek’s Real Robot One (RR1) project is a fully-featured 6+1-axis robot arm based on 3D-printed parts and widely available electronics. The initial release was constructed with PETG filament, custom gearboxes for transferring the motor torque to the actuators, and a plethora […]
We all know how annoying a ceiling fan can be when it isn’t balanced well and that annoyance perfectly demonstrates the necessity of a good, sturdy bearing. A ceiling fan’s bearing needs to allow for smooth rotational motion with as little friction as possible, while completely constraining movement in every other axis. Those properties make […]
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 […]
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 […]
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 […]
Building a capable robot is only half of the battle. To take advantage of that robot, you’ll need a good way to control it. When it makes sense, you can pre-program movements. But when you want to control a robot in real time, you need a suitable controller. Conventional joysticks and gamepads don’t translate well […]
For those with an interest in robotics, there is little in this world more enticing than a robot arm. A rover may be able to drive around, but so can a cheap RC car. A robot arm, on the other hand, can do real work, like stacking blocks or moving colored balls from one bin […]
To give an electric car more range, you need a bigger battery pack. But that adds weight, so you need bigger motors and more battery capacity to compensate. This creates a vicious cycle and robot arms are susceptible to a similar problem. A robot arm needs to lift its own weight in addition to whatever […]
