Hackaday Prize Entry: SafeRanger, a Roving Power Plant Monitor

Posted on by

Engineering student [Varun Suresh] designed his SafeRanger rover to inspect oil and gas power plants for abnormal temperatures as well as gas leaks. The rover explores critical areas of the factory, and data is sent to a control center for analysis.

[Varun] built his robot around a Devastator chassis kit from DFRobot, and equipped it with a FLIR Lepton thermal camera and an MQ2 gas sensor, both monitored by a Raspberry Pi. The twin brushless DC motors are controlled by an L293D motor driver IC in conjunction with an Arduino Nano; steering is accomplished with an HC-05 Bluetooth module and …read more

Hackaday Prize Entry: Engine Control Units and Arduinos

Posted on by

The modern internal combustion engine is an engineering marvel. We’re light-years ahead of simple big blocks and carburetors, and now there are very fast, very capable computers sensing adjusting the spark timing, monitoring the throttle position, and providing a specific amount of power to the wheels at any one time. For the last few years [Josh] has been building a fully-featured engine management system, and now he’s entered it in the Hackaday Prize.

The Speeduino project is, as the name would suggest, built around the Arduino platform. In this case, an Arduino Mega. The number of pins and PWMs is …read more

Hackaday Prize Entry: Archelon ROV Explores the Ocean

Posted on by

Acendtech Robotics is a 4H robotics club located in Freehold, NJ, and their centerpiece project is the Archelon, an underwater drone they built out of PVC pipes. It’s also a Hackaday Prize entry designed to monitor marine traffic, the seabed, piers, jetties, and other underwater constructions.

The Archelon uses eight thrusters constructed out of bilge pumps that have been hacked to add a propeller, leaving the motor sealed safely inside.

The ROV’s motors are controlled by an Arduino Mega along with two motor driver boards, each board driving two pairs of DC motors. There’s also a robot claw rotated by …read more

Hackaday Prize Entry: InspectorBot Aims to Look Underneath

Posted on by

Why bother crawling into that tiny sewer tunnel and getting coated in Cthulhu knows what — not to mention possibly getting stuck — when you can roll a robot in there instead? That’s what InspectorBot does. It’s [Dennis]’ entry for The Hackaday Prize and a finalist for our Best Product competition.

InspectorBot is a low-profile rover designed to check out the dark recesses of sewers, crawlspaces, and other icky places where humans either won’t fit or don’t want to go. Armed with a Raspberry Pi computer, it sports a high-definition camera pointed up and a regular webcam pointing forward for …read more

Hackaday Prize Entry: Smart Composting System

Posted on by

Composting serves an important purpose in our society, reusing our food scraps and yard waste to fertilize gardens rather than fill up landfills. Knowing that most people don’t compost, [Darian Johnson] set out to create a Arduino-controlled composting system to make it as simple as possible. It monitors your bin’s moisture, temperature, and gas emissions to ensure it’s properly watered and aerated.

[Darian]’s project combines a MQ4 gas sensor that detects combustible gas, a soil moisture sensor, and a temperature and humidity probe. The nearby water reservoir is monitored by an ultrasonic sensor that keeps track of the water level; …read more

Hackaday Prize Entry: Robo-Dog Learns to Heel

Posted on by

[Radu Motisan] is working on a small rover whose primary trick is being able to identify its owner. Robo-Dog is his proof of concept, a rover that uses five ultrasonic sensors to move toward the nearest obstruction. Obviously, this isn’t the same as being able to recognize one person from another, but it’s a start.

The sensors were home-built using ultrasonic capsules soldered into a custom board, with the tube-shaped enclosures made out of PVC pipe. He made an ultrasonic beacon that uses a 556 timer IC to emit 40 KHz pulses so he can get the hang of steering …read more

Hackaday Prize Best Product Finalist: Reconfigurable Robots

Posted on by

Reconfigurable robots have been around for ages. One of the first and most popular reconfigurable robots came out of the MIT Media Lab, and last year, DTTO, a modular snake-like robot, won the 2016 Hackaday Prize. There’s a lot that can be learned from a robot that can turn from a walker to a swimmer to something that clambers over rough terrain, and [Salvador]’s EMME does just that. It’s a 3D printed robot and controller that’s the closest you can get to, ‘the Lego of robots’. All you need to do is plug some wheels into a controller and you’re …read more

Hackaday Prize Entry: FabDoc is Version Control for Project Images

Posted on by

FabDoc is an interesting concept that attempts to tackle a problem many of us didn’t realize we had. There are plenty of version control systems for software, but many projects also have a hardware element or assembly process. Those physical elements need to be documented, but that process does not easily fit the tools that make software development and collaboration easier. [Kevin Cheng] sums FabDoc up as “a system to capture time-lapse pictures as pre-commits.”

With FabDoc a camera automatically records the physical development process, allowing the developer to focus on work and review later. The images from the camera …read more

Hackaday Prize Best Product Finalist: Shape Shifting Structures For Space

Posted on by

While [Elon Musk] and [Jeff Bezos] are working on getting us to Mars and the Moon, [Ronald Jaramillo] is working on building structures once we get there. To that end, he’s been developing the ZBeam, two rolls of links that zip together like a zipper to form a rigid beam.

Initially stored in a compact cube targeted to eventually fit in a CubeSat’s dimension’s, 100 mm x 100 mm x 100 mm, the beam emerges from within the cube and will be able to connect with other cubes to form rigid structures. His hope is that they can one day …read more
