WP_Post Object ( [ID] => 3388 [post_author] => 638 [post_date] => 2018-04-01 17:09:40 [post_date_gmt] => 2018-04-01 07:09:40 [post_content] => Three essential tools for every handyman or woman. Includes our magnetic WristBuddy, an extendable, flexible magnetic flashlight and our three function COB headlamp!

1 - Magnetic WristBuddy:

The magnetic WristBuddy keeps everything within easy reach whether you’re under the hood, squeezing into a bathroom cabinet, up a ladder or just nailing a few 4×2’s together! Designed to hold lots of screws, nails, nuts and washers, the magnets are amply strong enough to also hold drill bits, hex keys, bolts, screwdrivers and even spanners. Made from extremely durable 1680D Oxford cloth, your WristBuddy will be with you for years to come.

2 - Magnetic, Extendable, Flexible Flashlight

  The perfect tool for finding that lost screw that rolled under your workbench or the pins that dropped onto the carpet! This bright, COB LED flashlight extends to a full 60cm (2ft), has a flexible neck and a strong magnet in the lens surround. It's also a wonderful aid for anyone with bad knees.

3 - Three Function COB LED Headlamp

How often have you wished for better lighting while doing a job? All you needed was a third hand with a flashlight, right? This tough, fully adjustable headlamp uses the latest Chip On Board LED technology for maximum performance. Set it for bright, normal or strobe function with a click of the switch. Weighing just 65 grams (2.25 oz), including the three AAA batteries, our headlamp can be worn hour after hour. And because it's both shock and water resistant, it's great for camping and fishing as well as in the home and workshop.

Special offer:

Bought separately, these three items are currently selling for a combined total of $27.40. For this week only, we have packaged all three for just $17.50 including free delivery.

The Robot That Sweats!

The Robot That Sweats!

Last Updated on

Humans aren’t the only ones who can break into a cold sweat – this robot does too! Meet Kengoro, a humanoid with over a hundred motors. Kengoro can do push ups for 11 minutes straight. That generates heat so, just like humans, Kengoro sweats!

They may be superior to we ‘mere mortals’ in terms of strength and endurance, but robots are a lot like us in more ways than you’d expect. When we exert a lot of effort with our muscles, we produce heat. When we do that, we need to cool down in order to regulate our body temperature. We do that naturally through sweating. Sweat cools our bodies as it evaporates. Now replace those muscles with motors that are in constant high torque demand and you have a robot that also needs a cooling system to avoid overheating.

Dynamic robots such as humanoids can do many human activities that are considered unsafe or less productive for a human to do. We get tired. Robots don’t. While it is true that they can overheat, malfunction, or bust a limb or two, robots are designed to give many years of service if given the right maintenance. And ‘wear and tear’ isn’t a problem because they can be rebuilt piece by piece! However, it is their motors that ultimately determine their lifespan. And the most common threat to the motors is overheating.

Cooling isn’t new… sweating is!
There is an existing cooling system for robots which usually comprise of active water cooling

Motors generate heat... sweat cools them!

with tubes, a radiator, and fans. But with a humanoid like Kengoro, which has over a hundred motors, there’s simply no room for such an elaborate system to be installed without compromising efficiency.

Japanese engineers found a solution to the problem, which is so simple, it’s ingenious! Humanoids are called such because their appearance and functions are patterned after humans. Following the principle of nurturing what is in nature, engineers devised a system that would make Kengoro follow the human’s cooling system – by letting it sweat!

Researchers from the University of Tokyo, led by Professor Masayuki Inabe used Kengoro’s skeletal structure as a coolant delivery system. The robot can sweat through its 3D printed skeletal frame, which is made of highly permeable metal that’s full of tiny gaps and tunnels similar to a sponge. These microchannels are where water can seep through and evaporate once it is out of the frame.

While tests show that the traditional radiator cooling system is still more effective in most situations, ‘sweating’ allows humanoids like Kengoro to handle continuous high torque activities. In other words, Kengoro can run at full power for longer without overheating its motors by sweating through its bones. Now, how cool is that?

Watch Kengoro work out…

Hmmm… I wonder if Kengoro will need a robot strength deodorant :)
