Project Aslan is a 3D-printed robotic sign language translator

With the lack of people capable of turning written or spoken words into sign language in Belgium, University of Antwerp masters students Guy Fierens, Stijn Huys, and Jasper Slaets have decided to do something about it. They built a robot known as Aslan, or Antwerp’s Sign Language Actuating Node, that can translate text into finger-spelled letters and numbers.

Project Aslan–now in the form of a single robotic arm and hand–is made from 25 3D-printed parts and uses an Arduino Due, 16 servos, and three motor controllers. Because of its 3D-printed nature and the availability of other components used, the low-cost design will be able to be produced locally.

The robot works by receiving information from a local network, and checking for updated sign languages from all over the world. Users connected to the network can send messages, which then activate the hand, elbow, and finger joints to process the messages.

Although it is one arm now, work will continue with future masters students, focusing on expanding to a two-arm design, implementing a face, and even integrating a webcam into the system. For more info, you can visit the project’s website here as well as its write-up on 3D Hubs.

WinchBot is a robotic arm composed of 3 winches and 5 servos

Using an Arduino Uno along with a Raspberry Pi for control, hacker “HomoFaciens” came up with this clever delta-style robot.

If you were going to make a robot with five servos, many Makers would make a robot arm with them and call it a day. HomoFaciens, however, who is known for making amazing machines with minimal tools and improvised materials, instead made something that seems to be a cross between a delta robot and a Skycam.

His device, called “WinchBot,” uses three winches attached to an equilateral triangle frame to move a slider on a central pivoting square rod. This allows the robot’s 5-axis “hand” to be positioned within the robot’s work area. The servos are then tasked with keeping everything in the correct orientation, as well as opening and closing the gripper as needed.

If you’d like more details than given in the very entertaining video seen here, be sure to check out the project’s write-up.

uArm Swift is an open-source robotic assistant for your desktop

Need a hand? The UFACTORY team has got you covered with the uArm Swift, an open-source robotic assistant for your desktop.

The four-axis uArm Swift is a smaller and sleeker version of the company’s original device from 2014. Based on an Arduino Mega, the robot is capable of lifting 500 grams (1.1 pounds) with a working range of 5 to 32 centimeters (2 to 12.6 inches).

UFACTORY has launched two different models of the consumer-friendly arm on Indiegogo. Whereas the basic model is perfect for beginners and those looking to tinker around with robotics, the Swift Pro is designed for a more experienced Maker crowd with a stronger motor, more precision, and greater versatility. It also boasts position repeatability down to 0.2mm.

With a little programming, the Pro can perform a wide range of tasks from 3D printing to laser engraving to picking up and moving game pieces. You can even create your own actions through the team’s Blockly-based graphical software, uArm Studio, as well as control your Swift either directly from a keyboard-and-mouse setup, by making gestures, or over Bluetooth from the uArm Play mobile app.

The Swift is extendable with three different end-effectors (suction cup, metallic gripper, and universal holder) and a built-in socket for selected Seeed Grove modules. But that’s not all. Attach an OpenMV Cam and the robotic arm can detect faces, colors, and markers.

These Makers built a gesture-controlled robotic arm

Using a Kinect sensor with MATLAB/Simulink and an Arduino, B.Avinash and J.Karthikeyan made a robotic arm to mimic their every move.

If you need a robotic arm to follow your movements, the Kinect sensor is a great place to start. On the other hand, it’s a long leap programming-wise to go from sensor input to coordinated movement of servo motors. Through a toolchain stretching from the sensor itself, to a computer, and finally to an Arduino Mega controlling the servos directly, Avinash and Karthikeyan did just that.

For their process, the computer takes data from the Kinect sensor, then translates it into servo angles using the MATLAB and Simulink computer programs. Resulting data is then fed into the Arduino via a serial connection, which controls the robot’s movements appropriately with a slight delay.

Sandwich bot gets peanut butter everywhere but the bread

What do you do when you’re the Queen of S****y Robots and you’re in the mood for a peanut butter and jelly sandwich? You have a remote-controlled bot make one for you, of course. This is exactly what Simone Giertz set out to do in her latest hilarious project using a pair of robotic arms: one holds a plastic knife for spreading, while the other is puppeteered by her friend, Fiona.

Although this sandwich robot may not be making any PB&Js anytime soon, Giertz’s video will surely have you LOL-ing. Enjoy!

Simple Robotic Arm Made out Of Cardboard Pieces

Primary image

What does it do?

Just a simple robotic arm that is controlled by potentiometers.

This is another project that I have done so far at my internship at the Boca Bearing Company. I was having some extra time waiting for some parts to arrive in the mail so I decided to do a quick simple project. As with the other projects that I have done here at Boca Bearings, I was to document everything about the project. So the following instuctions is taken from a post on the company's blog at http://bocabearingsworkshop.blogspot.com/2015/10/simple-robotic-arm-made-out-of.html

robotic arm control with arduino nunchuck

Primary image

What does it do?

Pick things up . Manual control using Nunchuck

I found some micro servos lying around and thought of making this robotic arm. I had some broken blinds and got the bracket to use for the servos and some scrap plastics in my toolbox. Its a prototype for my upcoming bigger robotic arm with better servo. I added nunchuck control for manual control. In the future I will be adding sensors maybe mounting the arduino underneath the box . Im happy with the result and will be making more! I had more projects going on and this is one of them.

Didnt spend anything in building this. Hope you like it.
