New Term For Art: Sculptural Robotics

September 21, 2010 by Jakob Griffith 10 Comments

[Dan Roe] has been working on Sculptural Robotics for quite some time, and most recently presented his newest creation: Solar Flowers 2010. Typically, Sculptural Robotics (coined by [Dan] himself) are stand alone, static art presentations made from electronic components and wire. [Dan] of course has taken it quite a bit further; giving all his sculptures life using solar panels, motors, engine circuits, and more. Making them zero emission, and beautiful at the same time. You can catch four videos after the jump of his moving sculptures. Not that we’re picking favorites, but the dragonfly is pretty amazing if we do say so ourselves.

Seaswarm: We Can Clean Up The Gulf In A Month

August 29, 2010 by Mike Szczys 48 Comments

Want to clean up the Gulf of Mexico oil spill in one month? Seaswarm says it can be done with 5000 floating robots.

As the name implies, the project uses swarm robotics. Each unit draws power from the sun, and drags around a conveyor belt of oil absorbent nanofabric that doesn’t get wet in water. Once the fabric is saturated with crude it can be removed using heat; not a task the swarm can do by itself. But get this: after separating oil from nanofabric both can be used again. That means you get the environmental benefit of cleaning up the Gulf, not throwing away your collection medium, and the oil is once again a usable commodity. Sounds like a lot of high promises, but take a look at the video after the break and decide for yourself.

Wifi Hotspot Powered By Wind Turbine And Solar Panel

Students at the Rochester Institute of technology have put together this WiFi hotspot that is powered by a wind turbine and a solar panel. It gets its signal through a parabolic antenna pointed at a near by building and repeats it for use in the vicinity. They are using a 30W solar panel, along with a 1/4 horse power 90V DC motor to charge two 6V batteries in series. On a windy day, the turbine has yielded 120W. Something interesting to note is a comment they made about blades. Though the ultimately decided to mimic a commercial design for wind turbines, they found the most efficient to be a single wood prop. Unfortunately, that prop was destroyed.

Solar MintyBoost

July 10, 2010 by Devlin Thyne 9 Comments

We first wrote about the MintyBoost back in 2006. Today, Adafruit has created a tutorial for making a solar powered MintyBoost. Using a MintyBoost, a solar panel, LiPo battery and a charger, they built on their Solar LiPoly tutorial. They fed the power tap output of the LiPoly charger into the battery input of the MintyBoost to perform the voltage step-up for USB devices. Based on an instructable that used SparkFun parts, this tutorial shows how to use parts that are available from one source. We hear that there will be some evolution of the MintyBoost coming down the line that will including charging capabilities.

Sun Tracking Solar Panel

May 24, 2010 by Caleb Kraft 17 Comments

As we all know, a solar panel must be exposed to the most amount of sunlight possible to reach full efficiency. A solid mount limits the amount of time that the panel is fully exposed to direct sunlight. The solution is to build a pivoting mount that automates the process of aiming at the sun.

[bwitmer] takes us through the process of building one out of some wood and old bicycle rims. He bought a pre made tracking unit to control his actuator, but we think many of you here could rig something up on your own.

BAMF2010: SolarPump Charging Station

May 23, 2010 by Phil Burgess 18 Comments

Amidst the noise of a bazillion robots and Tesla coils at the 2010 Bay Area Maker Faire, we located a bubble of usable WiFi, and got a nearby power charge to boot. If nothing else here, we want this:

The SolarPump Charging Station is a self-contained oasis of free power for laptops, cel phones and even electric bikes. This charging station is one of several designs created by Sol Design Labs of sunny Austin, Texas. No bigger than a bus stop (and way cooler looking), it’s like the ultimate case mod, repurposing a vintage Citgo gas pump and recycled metals for more modern needs. Three large Sanyo solar panels provide power for devices and shade for users, while topping off the internal 24V 100AH battery for nighttime use (with LED lighting) or cloudy days. The end result transcends “green” — the SolarPump is simply appealing at a visceral level, managing to be simultaneously fun, attractive and practical. Did we mention wanting one? We totally want one.

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.
