Pneumatic Memory Chip: Researchers have developed an air-powered memory system. The purpose of this memory chip is to direct the soft robots. These robots are the composition of soft and flexible materials. One of the quoted examples in literature is Harvard’s Octopus-like Tentacle. Moreover, these soft robots do delicate jobs.
Since we are talking about soft robots. So, they are the products of electronics. Furthermore, their cost is the function of size, power demands, and electronic components. The University of California (UCR) Researcher achieved this design improvement in Soft Robots. Their efforts created a Pneumatic Computer Memory Chip (RAM). As a result, soft robots can manage the effective playing piano.
How does this Pneumatic memory chip work?
The working principle of these air-powered memory chips is like traditional chips. After all, these are chips. And they store the data. These memory chips use the air pressure in the microfluidic valve in pistons. In comparison, traditional chips use transistors to serve the purpose of storage. Storing the information means retaining the binary values. Furthermore, the presence and absence of air pressure lead towards binary values of 1 and 0. These logic levels 1 and 0 refer to the true and false levels.
Can this Pneumatic Memory keep the data?
One may raise questions on the effectiveness of these Pneumatic memory chips. Because of its perseverance of air pressure in mechanical valves. Because these absence and presence refer to the vacuum (false = 0) or presence ( True=1). Furthermore, efficiency depends upon the accurate detection of air pressure. That is the job of sensing instruments.
Practical Realization of Pneumatic Memory Chip in Soft Robots
These microfluidic valves control both the liquid and air pressure in the system. Even in the absence of an air supply line. These valves remain sealed against a pressure difference. So, it will provide trapped pressure differentials. Later, these differentials behave as memories and control the robot’s actuators.
Bulky, expensive, and power-consuming electronic hardware control Pneumatic robots. Thus, dense arrays of these valves can conduct advanced functions. Furthermore, they will reduce the amount of expensive, bulky, and power-consuming electronic gear. The pneumatic memory chip is only equal to an 8-bit memory chip. This fact makes a limiting factor.
Although, there is a need for more work in this sector. And, the researchers are planning to achieve the realization of autonomous robots. These robots will use the air-based CPU and memory. Hence, more complicated components and downsizing will realize the feasibility of Pneumatic Robots.
