A Chainsaw-Wielding Robot That Cuts Trees

Aside from swords, knives or lasers, chainsaws are one of the worst possible things incorporated to robots. These are especially dangerous for trees where this pruning robot is able to climb up and lop off multiple limbs that are reachable to it.

A pruning robot

A pruning robot is a great idea. This technology is an important one, too. This is because climbing trees and holding on using a hand, or no hands, while sawing tree branches is extremely dangerous, as injury rates are around ten times as much as someone working at a factory.

This teleoperated robot allows an operator to stand very far while a pruning is done. The robot is also able to do a good job. It climbs up and down the trees with no difficulty, while it is lopping off branches from trees through a spiral motion.

Weighing 13 kilograms, the robot is able to drive vertically up the trees within 6 – 25 centimeters or 2.3 – 9.8 inches in diameter at a speed of 0.25 meters per second. This is done while taking on branches that have a 5 centimeter or less diameter. It is also able to adapt automatically to a range of tree forms. Additionally, it is also energy efficient because it is able to passively support itself while on a tree with the use of its own weight that securely grips the trunk.

A lot of the testing done by the robot is in an ‘experimental forest.’ The trees in this forest seem ideal with them being about as perfect and straight like a sprouting pole for telephones. The continuing research entails making the pruning robot more flexible and robust in terms of various assortments of foliage and trees, and teaching the robot the difference among trees which it should prune and humans it shouldn’t.

This pruning robot called ‘A Pruning Robot with a Power-Saving Chainsaw Drive’ was presented during the 2013 IEEE International Conference on Mechatronics and Automation by Katsuyuki Hirai, Haruhisa Kawasaki and Yasuhiko Ishigure.

Conclusion

Meanwhile, tree services in Australia, such as tree lopping in Perth or tree pruning in Melbourne, which are completed by professionals and experts are currently available as this pruning robot is still subject under further testing and experimentation.

Brisbane And Solar Power – How Much Energy And Savings You Can Expect

Brisbane is dubbed as the sunshine state capital because of the 5.5 hours of peak sunlight average per day, according to PVWatts. But what do 5.5 hours of sun really translate to?

A great investment

A good quality solar power system installed properly and working efficiently will definitely yield savings at large. A 3 kW sized panel returns your investment by means of savings in 4 years, and $1,100 annual savings thereafter. How is this possible?

Abundance of sunshine

For a residential solar panel in Brisbane that is 85% efficient and north facing, a 1.5 kW sized system can yield 5.8 kWh daily. The bigger the size goes, the more output it generates. A 2 kW solar panel generates 9.4 kWh per day, 5 kW sized panel yields 23 kWh per day, and a 10kW solar panel can generate an output of 47 kWh per day. But what do these figures really mean?

Energy usage

Electric bills always indicate the power usage of the household in standard unit kilowatt-hours (kWh). This varies by season and by month, so it would be wise to study one’s power consumption pattern. With this, it would be easy to figure out how many kWh a household consumes on a daily average, and this will help with deciding the best size of solar panel to pick.

Solar power system prices and installation

Australia solar system prices for installation is among the lowest worldwide. And a number of companies offering solar power in Brisbane offer competitive prices. The federal government also provide discounts on installations through Australia’s RET or Renewable Energy Target. The value of the discount or incentive is subject to several factors, like system size and location, but is usually 30-40% off the installation cost. This incentive in place makes the country home to the world’s lowest solar power system prices. For the actual equipment, cheaper panels do not necessarily mean lower quality but always research on the brand you are eyeing and proceed with caution. Maintenance require inverter replacements every few years and the product warranty is usually 25 years.

Uninterrupted power

In order to ensure uninterrupted power service, a battery storage system is necessary, so you can still have solar electricity available even at night. Companies offering systems for solar power in Brisbane made battery storage systems affordable as well.

Vertical Roller Mill Product Information

A vertical roller mill is widely used in industrial settings. It is used for heavy duty applications such as in grinding clinker, raw meal, iron ore, ground granulated blast furnace slag or GGBFS, coal powder, limestone, coal gangue, coke powder, quartz, gypsum, bauxite, calcite, fly ash, pyrophyllite, volcanic ash, sandstone,  clay and other processing industry of metal and non-metal products.

Product Characteristics and Features

Vertical roller mills are generally used for its high grinding efficiency and lower energy consumption. This is ideal for large industrial companies that process materials in large quantities, due to its cost efficiency. It also requires lower metal consumption for every unit of product thereby making the production process less costly for the company.  Another positive feature of this equipment is its minimal sound emission which is ideal for its operators and people in the workplace. It also emits low levels of dust pollution which is good news for environment advocates who usually points fingers at industrial manufacturers for contributing carbon footprint and other environmental issues.

A vertical roller mill operates under negative pressure and also functions by grinding on the layer bed of the material. Another important point of vertical roller mills is that its operation employs simple process flow that involves grinding, drying and classifying all under in one unit. This means that there is no longer a need to purchase and operate a number of equipment to produce the intended output. The equipment also does not require large space to be operated and is generally light weight with tight layout. All in all, vertical roller mills are one of the most economical grinding machines that involve minimal employment of labor and civil works.

Vertical roller mills come in different sizes and are reliable when it comes to uniform and even particle size distribution. Its parts are also notably longer in life and can easily be replaced by a qualified technician. The quality of the equipment also depends on the brand or manufacturer.

Home Theater On A Budget

You may think that you have the best set up when it comes to your home theater but unless it has been installed there by professionals then there is a big chance that you could do better. There are simple tricks and techniques you could employ in order to make a big difference to your current set up without having to spend a lot of money. Having an HDTV as well as nice speakers does not guarantee you the best cinematic experience if the set up is not optimum. Here are some things you could do to get the best out of your audio and video system:

  • For the video, replacing an old model of television to an HDTV does not mean that you have everything in place. There some things that you should get right such as the best viewing distance for your HDTV. Upon purchasing your new television set, you might have thought where you are going to place it and the position but you might not be aware that there are specific distances in order to get that sweet viewing spot. The formula to get that distance is quite simple – all you have to do is double the size of the diagonal screen of your television and that is the inches that you should position your couch or chair away from your television screen.
  • You should also set up your television in order to get the best out of the settings. This can be done by purchasing a calibrating tool that is DVD-based. There are cheaper options and there are also those that have full features but you will have to pay a bit more.
  • The sound is one of the most important aspects in a home theater as it is on the same level as the video. Both should be at its optimum setting in order to get the best experience. The speakers should be placed in the right positions. Measure your distance away from the television and the speakers should also be the same distance away from each other. The angle should be between 22 to 30 degrees and make sure they are on the same level as your ears.

If after having tried the above tips and tricks does not seem to satisfy you and you could cash out into hiring wiring & installation specialists then it is best to do so.

Benefits Of CCTV In Municipal Pipe Inspection

In order to maintain a fully functioning municipal sewer system, it is important to perform the needed inspection of all municipal pipes. It is also the best way to perform preventive maintenance to make sure potential repair problems does not develop into something worse. The regular schedule for the inspection of the pipes should be followed religiously. Neglecting it could lead to various problems such as the buildup of sludge, corrosion, possibility of deterioration for the pipes, invasions of roots from trees above ground among other problems that can worsen as time goes by. If existing problems in the municipal sewer are not given the proper attention it deserves, there could be major issues in the future such as the pipe collapsing and major blockages. The result could impact the whole neighborhood as they experience plumbing outages. This is why it is important to perform maintenance regularly and to follow inspection schedule for the municipal sewers.

One of the modern technologies that helps make inspection faster and more convenient is the use of CCTV technology. Nowadays, municipal pipes are inspected with the help of CCTV technology. This type of technology will not only save time but also money compared to other types of inspection methods. With the use of the CCTV, professionals will be able to perform a visual inspection of the inside of the pipeline. The operator will be able to look into the entire pipeline and inspect if there are any signs of breakage, roots from tress, leaks, corroding pipes and other possible problems that could be a reason for the pipeline to fail or to disrupt its normal operation. CCTV can be used as inspection tool for pipes with varying diameters ranging from 4 inches up to the largest which is 60 inches.

Using this technology, the municipal pipe inspection can prove to be one way of preventing any failures in the pipeline system that can be otherwise very expensive to repair. There are various problems that can result from failures in the system but the most common are sludge buildup, mineral deposits, sediment buildup, scaling deposits, trash and debris accumulation, roots, erosion and many other major issues. If you have any problems with your pipeline, contact Pro-Jett.
