Wyvern quadcopter

May 3, 2010 by Mike Szczys 9 Comments

[William Etter] and his classmates built a quadcopter as a class project. We love the details of these builds and they came through with some thorough documentation. Some highlights that we enjoyed were reading about ABS body design and construction, their analysis of two versus three blade propellers, and their breadboarded control mechanism. You can see their success in the most recent post, but we all know that trial and error plays a role in these builds so we’re glad they’ve shared a collection of crashes with us.

Can’t get enough of this four-rotor action? Check out this project of a similar design.

Remote Control Reel Mower

May 3, 2010 by Mike Szczys 19 Comments

Challenged by hot days and steep turf [Grayson Sigler] modified his reel mower to use electric motors. The end product will be radio controlled but he lacked the necessary parts to make it wireless right now. Not to be deterred, he used a wired controller for prototyping and testing that should be easily replaced once the parts arrive. Sadly, the grade of his yard causes the small wheels to slip so he tried inserting screws into the tread for added traction. The small mower lacks the weight and footprint that the Lawnbot400 enjoys. That being said, solar charging is one of the future goals so this build, which he named RoMOW, wins out on the green scale. We’ve included the prototype video after the break that shows the blades spinning away.

Forget The Rovio, Drive A Taxi With Your Mind.

April 29, 2010 by Caleb Kraft 8 Comments

While browsing through flicker this morning, we spotted this interesting image. Two radio controlled cars hooked to Arduinos. What was going on? What is [knolleary] doing with them? We couldn’t find any information so we clicked through to his personal site. What we found was a quite interesting story about how he set up a race between two taxi cabs being controlled by the Emotiv headsets for the BBC. Yeah, forget driving a Rovio around with your mind. We’re still a bit curious about the two bumper cars in the picture. We can see that his tests were done on a blue radio controlled mini, so what are the bumper cars for? Did any of you catch this on the air? How well did the taxis drive? Was he using the facial expressions or the concentration?

Aerial Photography platforms

[Eric Austin] is using a Canon 7D with this RC helicopter to capture some amazing HD video. His success has manifested itself in a company that is now manufacturing these platforms ready-to-use. Take a look at their blog to see some of the hardware they’re working on, such as a tricopter and hexacopter photo platforms. We’ve also embedded a video after the break of the unit seen above and the stunning shots it’s able to grab.

Steam Powered Tank

March 12, 2010 by Mike Szczys 38 Comments

This steam-powered tank is really something of a steam-electric hybrid. Steam provides the locomotion, but an electrical system provides the remote control and steering. A full boiler will provide 10-15 minutes of operation which you can see in the video after the break. Before you leave a nasty comment: Yes, we realize this project is from several years ago. It’s new to us and the completion date doesn’t diminish the novelty of this well-executed build. This is the quality and uniqueness we’re used to seeing from [Crabfu].

RC Truck Source For Robotics Platform

March 5, 2010 by Mike Szczys 15 Comments

[Michael] sent us a link to his RC robotic platform. He started with the same RC toy as the iPhone Robot (CAR) but ended up with a blank slate waiting for more features. What he has is an Arduino with a motor driver, three bump switches for the front and rear, and a XBee module. On the other side of things he used a SparkFun USB to FTDI connector to interface another XBee module with a PC in order to use Processing.

In the clip after the break you can see the motor control needs to have more fine-tuning done so the beast isn’t just out of control when running. But there’s a ton of potential here. It should not be a problem to add at lease rudimentary video feedback from the device. The Arduino is currently only being used marginally, leaving plenty of space to add on-board sensing such as IR, proximity, or light.

It’s a clean start, we expect to see updates! Continue reading “RC Truck Source For Robotics Platform” →

Sukhoi Su-27 Jet Build Throws Down

February 18, 2010 by Mike Szczys 53 Comments

This no model, but a fully functioning RC jet. The Sukhoi Su-27 was the Soviet Union’s counterpart of the F15 and this 1/6.5 scaled version measures eleven feet long and is fully controllable. As if the 80-page build log wasn’t enough, the flight video after the break is nothing short of jaw-dropping. The test flights end in smooth landings but with all the time that went into the project that’s got to be nerve-wracking.
