Miro-E has seen incredible popularity with parents from UAE and the rest of Middle East, specifically in urban setups in Dubai and the rest of GCC.

Here are some frequently asked questions about Moro-E:

Why does my robot sound like a satellite?

The main battery voltage is low, as indicated by this sound. MiRo’s batteries should be recharged.

Why does my robot sound like an airport?

This sound means the system is being updated via the internet. You should strive to be patient, which is tough in today’s fast-paced environment.

Why is the update not working (with error message “git pull failed”)?

Your robot must be linked to the internet in order to update the on-board software. If not, connect your robot to a network by entering network credentials and rebooting it, then verify that it has a valid IP address and that the network to which it is attached is likewise linked to the internet. Now attempt the update once more.

Why is the update not working (with error message “lock could not be acquired”)?

Automatic system updates were conducted automatically in older programme versions on a regular basis. These are now carried out during robot software updates, however you cannot do a robot software update while a system upgrade is in progress. Please wait a few minutes for the update to complete, after which you will be ready to proceed.

To minimise system corruption, it is advised to avoid rebooting in this circumstance and instead wait for the updates to finish. Following the update, system updates will be made only when necessary, eliminating this issue.

Why is the update not working (with error message “server certificate verification failed”)?

This occurs when the on-board computer fails to update its system time, preventing distant certificates from being checked. This can happen if the robot’s network blocks NTP (time server) packets.

You can either contact your system administrator or connect through SSH and manually set the time. Support for setting the time from MiRoapp will be implemented in the near future, providing another solution to this problem.

Why is the update not working (software state is ‘modified’)?

It is strongly advised that you do not make any changes to the MDK directory on-board your robot. If you do, the software’s “State” on the Software manager page will be “changed,” and you won’t be able to update it.

You can revert any modifications to the MDK directory by signing in to your robot. Please save any files you want to keep first, and then follow the steps below.

• The first step is to restore the MDK repository to its previous state.
• The second step is to remove any additional files from the MDK directory. You can find them as follows; you should manually delete them.

Why does my robot just sit there wagging its tail with its eyes half-closed?

When you turn on MiRo, the touch sensors self-calibrate. To avoid miscalibration of these sensors after restarting MiRo, please only touch the grey (lower) areas of the case. If this is the case, you can simply re-calibrate the sensors by following the steps below. Perform an Embedded reset by simply touching the grey sections of the casing.

Why can I not reach the on-board ROS master?

You’ll be able to query the ROS master on the robot to see a list of ROS topics broadcast by the robot after your environment is configured appropriately. You might get something like this instead:

ERROR: Cannot communicate with master! $ rostopic list The most likely issue is that the ROS MASTER URI variable is incorrectly set—that is, it does not contain your robot’s address. To learn how to properly set this, go to Off-board.

You must have observed that matter changes form which converts water into vapor and ice into water. Why does this happen? Changing states of matter occur when matter absorbs energy or loses energy. The atoms in the substance act upon the external stimuli which compel it to change form. An increase in kinetic energy leads to the atoms moving away from each other and thereby changing the state of matter.

What are the different states of matter? We are aware that there are three states of matter; solid, liquid, and gas. In the solid-state, atom molecules are tightly packed against each other and hence the substance is more compact, having great intermolecular strength. In a liquid state, the atoms are slightly spaced between each other and hence the force of attraction is lesser than that of solid-state. In a gas state, the atoms are far apart and thus have very little force of attraction.

To summarize the above, you can say when there is a change in pressure or temperature of a substance, its state of matter also changes.

Change of state from Liquids to Solids:

How do you convert water into ice cubes? The process is simply by filling the tray with water and then putting it in the freezer. But do you know what magic happens behind cool doors?

When you place the tray in the chiller section, a transfer of heat occurs between the cool air in the fridge and the warm tray. Water in the tray loses its heat due to the cool temperatures within and the molecules become more compact due to the force of attraction. This process continues till the atoms become very compact, leaving no more space and getting fixed in one position. This is when water becomes ice. The temperature at which water gets converted into ice is called the freezing point.

Change of state from Solid to Liquid:

Now if you take the same ice cube and expose it to outside temperature by leaving it on a plate in a warm room, the cube will melt. The warm air is absorbed by the cube and this energy forces the particles to separate from each other, thereby the ice loses its fixed position. In this way, solids change to liquids, and the temperature at which it happens is called the melting point.

Change of state from Liquid to Gas:

Liquids when heated turn into gas. When you boil water in a pot, after a while, you will notice that the amount of water has reduced, because it gets converted into gas and evaporates in the atmosphere. This happens as the particles in liquid water get enough energy to overcome the forces of attraction, and therefore the molecules separate until it becomes gas. The process in which a liquid boils and changes to a gas is called vaporization.

Change of state from Gas to Liquids:

When you close the lid of the vessel in which water is boiling, you will see some water droplets on the lid. This is because vapor came in touch with the cooler lid surface, so it lost its energy and it no more had the strength to overcome the forces of attraction. The process in which gas turns into water is called condensation.

Carolina has been a biology supply company, associated with schools, colleges, & home-tutoring groups. Many K-12 educational institutes in Dubai and GCC regions, trust Carolina for their laboratory set-up and rely on its learning modules, to make Science more fun for students.

Carolina’s module on ‘Properties and States of Matter’ is specially designed for students of Grades 6-12. The learning kit includes a set of visual, digital, and hands-on resources to support teacher instruction and provide students with the skills to master key concepts on properties and states of matter. When kids conduct experimentation themselves, they feel more confident and are able to grasp concepts well. If you reside in the UAE, across the Middle East, simply send us a request and we will arrange for a demo at the earliest:

Every parent wishes to give his or her child access to the best level of education. However, with good education comes a great amount of homework and coursework. This ends up causing tons of anxiousness and lack of motivation among students. In order to be successful at school, every student needs to take a keen interest in the homework given by teachers. While this doesn’t mean you spend hours hand-holding them, you can support and encourage them in multiple ways. Motivating your students with their homework will not only help them understand subjects better but also act as a great bonding tool. Here are a few ways you can successfully encourage your child to finish their homework in an effective manner.

#1 Explore the Next Learning Platform

The generation of students today is different and hence they require different tools and features to effectively study and do their homework. This is why using the Next Learning Platform is a highly impactful idea. Numerous educators across Dubai, UAE, GCC and the Middle East are using this platform to not only conduct live lessons and assign homework but to also track homework and performance of individual students.

#2 Create a homework friendly space

Setting up a dedicated space for your kids to do their homework is very important. It not only promotes increased focus but also creates an environment where your kids feel comfortable studying. This space should have supplies like pens, pencils, an eraser, a stapler etc. so they do not have to get up every now and then.

#3 Decide regular ‘homework hours’

Some kids like to finish their homework right after school, some wait until they get a snack and some do it after dinner. Every child is different and works best at different hours. So, it is important to create a schedule for homework and follow it religiously. This will encourage increased retention and promote persistence and discipline among them.

#4 Avoid creating any distractions

While your child is finishing their coursework, make sure you don’t cause any distractions by speaking too loudly on the phone or switching on the TV that is in line with their vision. By keeping distractions to a minimum, you’re allowing your child to concentrate.

#5 Praise their hard work

Kids thrive through positive reinforcements. So, always make it a point to recognise their efforts and praise them as well. Make it a point to mention their academic achievements or applaud their completed homework in front of the family. This simple practice lays a highly positive impact on students and motivates them to study often.

#6 Remember to take breaks

It’s unhealthy for your child to over-function and under-perform. This is why it is important for them to take breaks between their homework. You can create a schedule wherein after each subject they can take a small break and do whatever they like. In this way, the child will not feel overburdened or exhausted.

#7 Know the teacher

This may sound like a no-brainer but it is critical when it comes to the overall performance of your kid. Having a comfortable relationship with the teacher allows you to understand their teaching pattern and in turn, helps your child comprehend the kind of homework they give effectively.

These are just a few steps out of the many that you can try in order to motivate your child to do their homework. To help your kid be at par with the global standards of education, it is important for parents and guardians to actively take interest in their child’s education and encourage them to do better every step of the way.

Today everything in the world has gone digital, which is why, our kids spend more time in front of the screen than outside in the backyard. This ever-growing pattern proves that children and pre-teens across the globe are getting more and more addicted to their digital devices with every passing day. While it is important for kids to be technologically savvy but it is equally vital for them to reduce their excessive screen time. The solution here is to strike a balance between the two by drawing out some interesting ways to reduce screen time for kids. However, first, let’s understand why excessive screen time is something parents should be concerned about.

While digital devices are a significant part of many children’s lives now, long hours in front of the screen can cause a whole range of health issues such as chronic fatigue, exhaustion, headaches, neck and shoulder pain, strained eyes and much more. While cutting off total access to digital devices is impossible now, here are some interesting ways to limit their usage.

#1 Create ‘technology-free’ zones

Children today have the habit of carrying their smartphones or tablets wherever they go. It is ideal to establish zones in your house that are strictly technology-free. For example, no cellular devices, video games or tablets are allowed in the kitchen or the dining room. Those areas are reserved just for healthy family discussions.

#2 Make use of their screen-time productively

While children today simply cannot escape technology, parents can make sure they are making good use of it. For example, parents and educators across Dubai, UAE, GCC and the Middle East are signing their kids up on CodeMonkey where they can learn coding online in a fun, engaging and interactive manner in a game-based environment. In this way, they can make good use of their time in front of the screen.

#3 Set a ‘Digital Detox’ time

Set aside some amount of time during the day when the entire family has to unplug from any and all digital devices. This time can be used to catch up with family members and spend quality time together. However, it is important for the entire family to follow this rule and not just make the children do it.

#4 Explain the reason behind limited screen-time

Children today are much smarter than we think. Don’t cut off their access to technology without giving them a legitimate reason. They might consider this treatment ‘harsh’ or ‘mean’ and resist your efforts to limit screen time. Instead, make them understand the disadvantages and the harmful consequences of digital explosion. In that case, they are more likely to follow the rules you have set.

#5 Encourage offline activities

Encourage your child to participate in activities that do not require a screen. In today’s scenario, it is so easy for your kid to become reliant on technology for entertainment. This is why you must encourage activities like reading a book, playing sports, exploring nature etc. A good way of making them interested in offline activities is to practise them yourself. Children have the tendency to model their parents. If they see you enjoying a basketball game in your backyard, they are more likely to participate themselves.

Putting down the phone is certainly a challenging task for many young children today and it is a growing concern among parents. This is why setting some ground rules to limit screen time can help you and your child strike a balance between healthy access to technology and offline activities.
