HAMR: Swimming robo roach makes a splash

HAMR

HAMR, the robotic amphibious roach

There have been a few insect-robots like the RoboBee and VelociRoACH that have been created in the past and the latest insect robot is the HAMR, an amphibious roach. The HAMR or the Harvard Ambulatory MicroRobot was created by Harvard University.

In 2013, the actual HAMR was created and it was tether controlled. It measures 4.4 cm long and moves at a speed of 8.4 body lengths per second. It was created by using 23 microscopic layers of material that was sandwiched together and the patterns were cut out using laser.

The latest version of the HAMR weighs 1.65 grams and features four foot-pads on the four legs. This robotic roach created by the scientists is amphibious in nature. It can walk on land as well as swim on the surface of the water. The HAMR is also designed to walk underwater as long as it is desired, enabling the robot to explore new environments.


Working of the HAMR


When the HAMR enters the water, the foot pads provide the surface tension-induced buoyancy to prevent it from sinking. There is a provision for flaps on the underside of the pads that helps it to move across the water. The HAMR moves its legs in a swimming motion at a frequency of up to 10 Hertz. When the robot moves across the surface of the water it can evade any of the obstacles present and also reduce drag. The HAMR has four pairs of asymmetric flaps and customized swimming gait that help it to swim on the surface of the water. There is an unsteady interaction created between the passive flaps of the robot and the surrounding water which enables the robot to swim forward and turn.

From the underside of the pads, the HAMR can apply electric current to the water. This is electrowetting whereby the voltage that is applied will reduce the contact angle between an object and the water surface. Due to this the surface tension breaks and the robot sinks.

The robot uses the same mechanism to walk along the bottom of the water just like it walks on land. There is a watertight coating of a polymer known as Parylene to prevent shorting of the HAMR.

In order to get onto the land the HAMR has to break through the surface. A water surface tension force which is almost twice the robotic weight pushes the robot down. There is also an induced torque that increases the friction on the hind legs of the robot. To overcome this difficulty, the scientists have stiffened the transmission of the HAMR and put soft pads to the front legs of the robot. This helps to increase the payload capacity and the friction gets redistributed to enable the robot to climb. The robot then walks up an incline and breaks out of the water surface.

There is a possibility of using technology that gets its inspiration from geckos such as the gecko-inspired adhesives or jumping mechanisms where the HAMR can come out of the water without the use of a ramp or a slope.

Google Duplex: Google's Eerie Human Phone Bot is Ready for the Real World

Google Duplex gets a Redo

These days everyone is on the AI bandwagon, from apps to gaming, you can see AI on all these platforms. So why not get AI to book appointments and reservations at restaurants? That’s what Google thought back in May when it released a bot to make reservations and other stuff, called Google Duplex. On first hearing the voice, many thought it was weird and just didn’t sound right.

At the Google’s developer conference in May, a bot or AI or Google Duplex was heard calling a salon and a restaurant to book a reservation on behalf of a human. This initial show of Duplex caused many to raise a number of issues with the chat bot, one of them being that the person on the other end did not know that they were talking to a chat bot and the other that they did not even know they were being recorded. Both of these issues significantly invades a person’s privacy and the said person is unaware of both these issues.

Google Duplex to get a redo:

Google has since then taken these issues seriously and a few weeks before Google Duplex can be used by a small number of small businesses and users, Duplex has got a big redo.

Google aims to address these issues at a time when it has released a set of principles that prevents Googlers from using AI tech in technologies that could affect or violate human rights.

Google Duplex in a Demonstration: 


This time around in order to show case the new and improved version of Duplex, Google used a Hummus shop down the road from their headquarters in Mountain View, California. Google got Duplex to make a reservation at the restaurant which they played through the restaurant’s speakers so that the assembled reporters could hear Google Duplex in action.

As soon Duplex hit the ears of all those present a few differences were immediately apparent. Google’s Duplex informed the person on the other line that it is Google’s automated booking service and that it’ll be recording the call.

There were even Google’s representatives present to answer any questions that the reporters might have. The reporters were even given a chance to rotate around and answer the phone. Google’s duplex was being made to call through Google assistant from a laptop just a few feet away in the restaurant.

While many reporters took their turn at the restaurant, many of them tried to trip up the chat bot and when the chat bot was unable to satisfactorily complete the call, another person came on line which one would barely notice as a real human being.

 

No regrets: 


Google had no regrets at showing Duplex at their developer’s conference back in May. They said they were only demonstrating the technology side of things and all the feedback that they received was really helpful in making changes and going forward.

But another question arises now, Do people really feel a need to fulfill their obligations of attending an appointment, especially now that a bot is placing an order on their behalf?

Intel: Pushing the Boundaries of Modern Computers at Computex

Intel

Intel to Boost Battery Life

Intel to boost battery life, yes Intel is all about doubling battery life by introducing a simple tech. Intel believes that battery life can be boosted by in fact reducing the consumption of energy by the display screens in laptops. At an announcement at Computex in Taipei, Intel recently created quite a stir by saying that they, by reducing the display screen’s battery’s consumption, they could actually double the battery life of a laptop device.

The most energy hungry part in a laptop is the display, so if the consumption of energy by the display is reduced, the battery life of a laptop can be increased. Currently laptop displays use about 2 watts. Intel says that by bringing down consumption to 1 watt means that we could see even 28 hour laptop battery life.

How is Intel going to boost battery life? 


One way by which Intel plans on boosting battery life and reducing display consumption is by co-engineering low power display technology. This tech co- created by Intel appears in a 1 watt panel manufactured by Innolux and Sharp, which apparently cuts LCD power consumption by half.

Testing of these panels by Intel: 


Intel says that it has seen laptops battery life increase from 20 hours to 24 hours using the tech and in some case it has also seen a jump in power of 4- 8 hours with the low power display technology.

This low power display tech is like a specification for manufacturing companies to meet, if these specifications are met while developing a display then Intel’s processors could use their integrated graphics card to adjust other settings such as refresh rate, brightness as well as various other settings that will boost battery life and reduce display consumption.

So in order to boost battery life, manufacturers would not only have to build display panels that match the low power consumption spec but also would have to use Intel processors to control the display and its settings, all to boost battery life of the laptop.

Cutting battery consumption by looking at the display was the right way to go as the display screens in devices are a major component that is known for consuming a lot of energy. As of now Sharp and Innolux are the only companies who have adopted the low power display tech in their manufacturing of display panels.

5G laptops in 2019: 


At the recent Computex, Intel also talked about selling Intel Processors for 5G connected PCs around the world. Intel is reportedly working with Acer, HP, Lenovo and Microsoft in bringing the first 5G connected PCs to the world in 2019.

Besides this Intel also plans on bringing out 10 more 4G PCs with partners like Acer, Dell, Asus and HP. This is in addition to the 25 4G connected PCs that are already on the market.

All this news at the Computex comes as Intel celebrates its 50th anniversary next month.
