The modular all-in-1 Brobot robotic arm’s FAQs

1.       After connecting accessories such as end tools, why can't I use the robotic arm when I click the corresponding function?

After connecting the accessories to the robot arm or controller, you need to click "Refresh" in the software for the accessories to work normally. You can check whether the accessories are connected normally in the "Operation Panel" on the right side of the software.

2.       What should I do when the software prompts an obstacle is detected?

When the desktop robotic arm encounters resistance, the current of the servo will suddenly increase. By reading the current value of the servo, you can determine whether an obstacle has been encountered. You can click the current threshold in "Settings"-"Obstacle Detection" to adjust the sensitivity of the robot arm.

3.       The software shows that the scale jump needs to calibrate the robot arm, but it prompts that the calibration has failed. What should I do?

Close the software, shake the arm of the robot arm a few times with your hands, then restart the controller, and perform the calibration again after the robot arm is turned on.

4.       What should I do if the education robot arm is abnormal during movement?

Immediately press the emergency stop button on the software. After pressing the button, the robotic arm loses its rigidity and the light band is in red alarm state.

5.       How do I calibrate the color sensor?

After confirming that the color sensor is connected to the software, click "Settings"-"Scene Demo". Place a white disc on the color sensor, click Calibration, and then place other color discs at will. Click the Photo to see if the displayed color is the color of the current disc.

How to plan a path on an automated floor scrubber?

[ddrobo]

Usually, due to the narrow roads in the back streets, manual cleaning is inefficient and costly. Wuhan DDROBO Robotics Co., Ltd. recently launched a small, multi-functional outdoor vacuum cleaner, which is the ideal solution for cleaning the back streets. Compact, easy to use and 100% electric, it enhances your city’s quality of life and attractiveness. With a turning radius of less than 2 meters, the street vacuum cleaner can move freely in the back streets. Thanks to the automatic follow-up system, the urban vacuum cleaner can automatically recognize and follow the operator, which is more comfortable than holding the broom to sweep the rubbish.

Electric Street Vacuum Cleaner in China

Street vacuum cleaner, also known as an urban vacuum cleaner or outdoor waste vacuum cleaner, etc., is a new type of cleaning equipment. It designed for picking up all kinds of waste that can pass through a tube 12cm in diameter. It deals efficiently with both industrial and urban waste: paper, cardboard, cigarette packets and butts, cans and glass, plastic or metal bottles, dog feces, dead leaves, waste trapped in tree grills, wood, steel and aluminum chips etc. Street vacuum cleaners are not very common in China, but in developed countries, it can be seen everywhere, such as airports, parks, warehouses, scenic spots, alleys, etc. 

Street vacuum cleaners are fully enclosed, centralized collection, avoiding secondary dust pollution, significantly reducing the concentration of TSP and PM2.5, and effectively improving the level of refinement operations. In addition, the vehicle also uses wireless mobile communication technology to transmit job data and images in real time to realize the “Internet of Things & Smart Sanitation” management mode.

Similar to the working principle of the traditional vacuum cleaner, the street vacuum cleaner uses the motor to drive the fan impeller to rotate at a high speed, so that the air in the impeller is discharged at a very high speed, and a transient vacuum is formed in the machine to form a certain negative pressure difference with the outside. Under the action, garbage is sucked into the machine to achieve the purpose of cleaning and vacuuming.

The street vacuum cleaner is mainly composed of a vacuum system, water cleaning system, air filtration system, garbage collection system, energy system, and follow-up motion system. The various sections are as follows:

1. Vacuum system: It consists of a fan and a series of pipes to provide enough vacuum for the vacuum cleaner to absorb the garbage on the road.

2. Water cleaning system: It consists of a water tank, booster pump, high-pressure water gun and nozzle. The main function is to use high-pressure water to clean road surface stains and settle dust.

3. Energy system: It consists of a battery and related control components to provide power for the vacuum cleaner.

4. Follow the movement system: It consists of the drive wheel, the steering wheel and the following motion control system. When the operator holds the follow-up signal transmitter, the vacuum cleaner will recognize the operator and follow his movements even in a crowded city context.

5. Garbage collection system: It consists of garbage bins and related sensors. The sensors can identify the height of the garbage in the bin and promptly remind the operator to handle the garbage.

6. Air filtration system: Filter the air sucked into the vacuum cleaner to prevent dust from entering the fan and discharging it into the air again.

Street Vacuum Cleaner – Give Warmth to Street Cleaners

In China, if you get up early, you will see a group of people in the streets of the city. They wear vests, struggled to move the tricycles with rubbish, and walk around in every corner of the city. They are the city's street cleaners. Whenever evening falls, there are a lot of dead leaves or rubbish left in the streets. But when we wake up the next day, we will find the streets are still neat and clean. This is the result of the hard work of the street cleaners early in the morning.

There is now a smart urban street vacuum cleaner on the market that can help reduce the workload of street cleaners. The waste vacuum cleaner is similar in function to a home vacuum cleaner, except that the model size is much larger. The street vacuum cleaner looks like a small car from the outside, but the difference is that there is a pipe on the machine to collect garbage.

The most special thing is that the vacuum cleaner does not require the driver to control the direction inside. The machine is designed with an automatic following system, which can intelligently identify and follow the movement of the sanitation workers.

With the urban vacuum cleaner, the sanitation workers just need to take it around the city streets. Just press a button, the vacuum cleaner will suck all kinds of garbage into the pipeline, and collect it in the back dustbin for centralized processing. In this way, the work of sanitation workers becomes very relaxed, and it is like walking on the streets.

Vacuum Cleaners

A vacuum cleaner is a device that causes suction in order to suck up dirt/particles and dust from floors, upholstery, draperies and other surfaces. It is generally electrically driven. There are basically 5 types of vacuum cleaners as mentioned below:

1.        Handheld Vacuum Cleaners

These vacuum cleaners are held by hand and used to suck up dirt from tight spaces and places that are difficult to reach. They are mostly used in rooms with very limited spaces and in cleaning cars and engine parts.

2.        Canister Vacuum Cleaners

This is another type of vacuum cleaner used in large and business properties. They come in different sizes and are used in cleaning carpets and bare floor surfaces. Canister vacuum cleaners are technologically enhanced and have multi-functionality with a separate Canister which is connected to a wand.

3.        Upright Vacuum Cleaners

The upright cleaner is the most popular and widely used device particularly suited for private households. It is a powerful device standing in an upright position and used for general house clean-ups for both carpets and bare floor surfaces.

4.        Stick Vacuum Cleaners

Used for cleaning narrow and tight places, it comes with a stick-like handle and is easy to manipulate and operate. It is effective in cleaning bare and hard floors, rugs and slim carpets.

5.        Robot Vacuum Cleaners

These are automated devices which require minimal hands-on control by the user. When switched on and placed on the intended area, it roams freely on its own covering every surface area of the house. Its sensors track and suck up every dirt and debris even in tight crevices.

China's Sanitation Equipment

With the rapid development of the economy, more and more people flock to the cities. At the same time, the amount of garbage is increasing sharply. This is a real challenge to urban sanitation machinery and sanitation workers. In 2019, some cities in China began to implement the garbage classification system, which also posted a new demand for sanitation equipment. China’s sanitation equipment are summarized as follows:

Garbage Truck

Garbage truck or dustcart refers to a truck specially designed to collect municipal solid waste and haul the collected waste to a solid waste treatment facility such as a landfill.

 Sweeper Truck

The sweeper truck is an efficient sweeping equipment that combines road sweeping, garbage collection and transportation. It can be widely used in urban streets, municipal squares, airport roads, urban residential areas, parks, etc. It can not only clean the garbage but also purify the air, thus ensuring that the road is clean and tidy, preventing dust from flying and maintaining the good working condition of the road.

 Street Sprinkler

Street sprinklers, also known as multi-functional green sprinklers, are used to clean roads, prevent dust, spray water, and spray pesticides, etc.

 Anti-Smog Mist Cannon

Anti-smog mist cannons, a large machine mounted on a truck that sprays nebulized water droplets, are a new weapon to combat air pollution. They are aimed at trapping and sinking dust particles in the air of Beijing and other worst-affected cities.

 Snow Blower

A snow blower or snow thrower is a machine for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway, railroad track, ice rink, or runway. It can use either electric power (line power or battery), or a gasoline or diesel engine to throw snow to another location or into a truck to be hauled away.

 Fecal Suction Truck

Fecal suction truck (also called Septic tank truck) is used to collect, transport and discharge dirty water, sludge, septic. It is suitable for cleaning the septic tank, cesspit, cesspool, gully, etc.
