Electronics-Free Soft Legged Robot

Pneumatic circuits without electronic components enable automatic control of the walking gait of a soft legged robot

Pneumatically actuated soft robots have recently shown promise for their ability to adapt to their environment. Previously, these robots have been controlled with electromechanical components such as valves and pumps that are typically bulky and expensive. In this work, we developed a soft legged walking robot that is controlled and powered by pressurized air. We designed soft valves and pneumatic circuits to control the walking direction of the robot. We used a soft ring oscillator circuit to generate the rhythmic oscillatory movement similar to central pattern generator circuits observed in nature. The robot’s walking pattern was inspired by biological quadrupeds like the African side neck turtle. We demonstrated a control circuit that allowed the robot to select between gaits for omnidirectional locomotion. We also equipped the robot with simple sensors to change its gait in response to interactions with the environment. This work represents a step towards fully autonomous, electronics-free walking robots. Applications include low-cost robotics for entertainment, such as toys, and robots that can operate in environments where electronics cannot function, such as MRI machines or mine shafts.

Electronics-Free Soft Legged Robot

Pneumatically-driven circuits without electronic components make it possible for automatic control of the strolling stride of a soft legged robotic

Pneumatically actuated soft robots have actually recently revealed assurance for their capacity to adjust to their atmosphere. Previously, these robots have actually been regulated with electromechanical components such as valves and also pumps that are pricey as well as usually large. In this work, we created a soft legged strolling robotic that is controlled and powered by pressurized air. We created pneumatically-driven circuits as well as soft shutoffs to control the walking direction of the robot. We used a soft ring oscillator circuit to generate the rhythmic oscillatory activity similar to central pattern generator circuits observed in nature. The robotic’s walking pattern was motivated by organic quadrupeds like the African side neck turtle. We demonstrated a control circuit that permitted the robotic to select between gaits for omnidirectional locomotion. We also furnished the robot with basic sensing units to transform its stride in response to communications with the setting. This work represents a step in the direction of totally self-governing, electronics-free walking robots. Applications consist of inexpensive robotics for home entertainment, such as toys, as well as robotics that can run in environments where electronics can not function, such as MRI makers or mine shafts.

Introduction to RTOS Part 4 – Memory Management | Digi-Key Electronics

Memory monitoring is essential in a multi-threaded atmosphere, as threads (or tasks) can rapidly take in every one of the alloted memory, triggering bizarre results such as overwritten memory areas or arbitrary processor resets.

The service to the difficulty in the video can be discovered here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-4-memory-management/6d4dfcaa1ff84f57a2098da8e6401d9c

In this video clip, we consider various methods to allot memory to a task and how to keep track of memory use in FreeRTOS.

The majority of C programs count on 3 various types of memory. Static memory is set apart prior to program implementation and made use of for points like static variables, constants, and global variables. Heap is enabled to expand dynamically and includes neighborhood variables stated at the feature degree. Ultimately, load may likewise expand dynamically and have to be especially allocated and also deallocated by the designer (e.g. making use of the malloc() and totally free() functions, respectively).

Whenever we develop a brand-new job in FreeRTOS, we have to designate it a collection amount of stack memory to use out of the global, available stack. Note that each task also needs one more area of heap for the Task Control Block (TCB), which stores various attributes concerning the job, such as its state and also priority.

We show ways to keep an eye on the pile in each string as well as the complete amount of load readily available to the system. When you overwhelm the pile or heap, we also reveal what occurs!

Samsung and LG Electronics both see operating profit in Q2

삼성전자 2분기 영업이익 8조1463억원, LG도 ‘가전’의 힘으로 선방

Samsung Electronics saw its earnings soar as sales were boosted by millions working and learning from home during the virus pandemic.
LG also topped market expectations on strong home appliance sales.
Kim Sungmin has our top story.
Samsung Electronics’ operating profit for the second quarter of 2020 amounted to around six-point-eight billion U.S. dollars.
That is the largest figure since the final quarter of 2018.
The South Korean tech giant said that while its total sales were down some 5-point-6 percent on-year amid COVID-19, its operating profits were up 23-and-a-half percent.
Samsung says this was largely driven by the increased profitability of memory chips and displays…, along with high demand for the IT products people have been using during lockdowns.
For the latter half of 2020, Samsung says it expects demand to rebound on products like smartphones while seeing firm demand for memory chips with the release of new mobile and game console models.
But there are some analysts who think global demand for semiconductors could decline in the following quarter.
“As companies have already bought sufficient stock of semiconductors in the first half of the year, they will have to reduce purchases in the following quarters. This could lead to decline in sales of semiconductors in the third quarter.”
Samsung Electronics aims to improve earnings in the following quarter by cutting production costs and improving efficiency.
However, it says the pandemic remains a constant source of uncertainty.
LG Electronics also managed to see an operating profit of 410-million U.S. dollars for the same period.
That is around 24% down from the second quarter of the previous year…, but is still higher than market expectations.
Focusing on sales of premium home appliances and reducing production costs…, the company recorded its highest ever second quarter operating profit to sales ratio.
It attributed the figure to customers’ increased interest in health and hygiene…, which led to higher sales of products like its drying machines and Styler outfit cleaning machines.
LG Electronics is also keeping its eyes on the global business environment amid COVID-19 but expects to see demand for some products like TVs pick up in the second half of the year.
