For a class project, University of Stuttgart students Ekin Sila Sahin, Lior Skoury, and Simon Treml came up with a unique painting robot named the Physical Twin. The Physical Twin travels on a three-wheeled chassis and mounts a four-axis arm with a brush. An operator controls the arm to dip the brush into an onboard paint container, […]
As you work on a project, lighting needs change dynamically. This can mean manual adjustment after manual adjustment, making do with generalized lighting, or having a helper hold a flashlight. Harry Gao, however, has a different solution in the form of a novel robotic task lamp. Gao’s 3D-printed device uses a USB camera to take images […]
Cable-mounted cameras can be a lot of fun for capturing moving footage. Although commercial cable cam options can be expensive, this system by Kasper Mortensen of MAKESOME is comprised of 3D-printed components with a receiver and wheel salvaged from an RC car. The build was meant to use some of the toy vehicle’s other components, however […]
Car spoilers can provide downforce for better performance, or simply give the appearance of speed. To take things to another level, Michael Rechtin designed his own custom wing that doesn’t just sit there, but pitches up and down via a pair of servos. The system utilizes an Arduino Nano along with an MPU-6050 for control, […]
Hand movements have long been used as a computer interface method, but as reported here, the MemGlove from a team of MIT CSAIL researchers takes things several steps further. This augmented glove can sense hand poses and how it’s applying pressure to an object. The wearable uses a novel arrangement of 16 electrodes to detect hand position […]
Seven-segment displays are normally diminutive items, able to show info from a clock or other device, in a size that’s easily tucked away when not needed. Jegatheesan Soundarapandian’s single-digit display, however, is just the opposite standing at nearly seven feet tall. The project is constructed out of cardboard, with a PVC spine for extra strength. Inside, […]
One of the simplest ways to make a mobile robot involves differential steering, where two wheels move at different speeds as needed to turn and a ball caster keeps it from tipping over. The MrK_Blockvader is an excellent take on this type of bot — demonstrated in the first clip below — featuring a 3D-printed blocky chassis, […]
Colin Furze decided that he needed a potato cannon for his DIY screw tank, and after making a manually loaded version, he automated the process. What he came up with uses a pair of linear actuators to push the barrel forward under Arduino control, allowing a potato-projectile to drop into the device’s chamber assembly. After a […]
Programming an Arduino to do simple things like turn on an LED or read a sensor is easy enough via the official IDE. However, think back to your earliest experiences with this type of hardware. While rewarding, getting everything set up correctly was certainly more of a challenge, requiring research that you now likely take […]
Irene Wolf is the owner a Passap E6000, a computerized knitting machine which features pair of needle beds, and decided it was time to give it an upgrade. In particular, she wanted the ability to control its rear needle bed automatically in a similar manner to the way the front is normally operated for extra […]
