Cozmo is a palm-sized robot from San Francisco-based Anki, and is actually an earlier version of an Anki robot called Vector. Vector has more capabilities in the area of artificial intelligence, thanks to its use of a processor that’s normally used to power smartphones. In contrast, Cozmo has a more basic main processor. So a lot of the computations that Cozmo makes … [Read More...]

FAQs
20 mA current loops, Part 2: Advanced features
Part 1 of this FAQ looked at the basics of the 20-mA current loop, why it is still used extensively, and its primary attributes. In this part, we’ll look at how the analog current loop is used for digitized signals and at self-powered loops – two developments which have extended its life and viability. Q: […]
20-mA current loops, Part 1: Basic functions
You’ve been given an “easy” assignment: get the low-rate data from a temperature sensor to a control computer located 100 feet (30 m) away, in an industrial setting. After much investigation and assessment, you choose a widely used standard called the 20-mA loop, which has been in use for over 50 years, rather than Wi-Fi, […]
SSDs: secure erase or sanitize?
When you’re done with a data storage drive, it’s nice to make sure that all of the data is scrubbed from it. A drive that’s returned, repurposed, or discarded can have personal or confidential data on it. Discarded drives have been found with everything from financial and medical data, email, and even pornography on them. […]
Digital phosphor oscilloscopes, persistence, and eye patterns
The digital phosphor oscilloscope takes its name from the old analog phosphor scope, but the resemblance is superficial. It was difficult to see the trace on the CRT screen in an analog scope because the electron beam dissipated instantly. To solve this problem, early engineers came up with the idea of coating the inner surface […]
What types of connectors are used in industrial motion control systems?
Most cable assemblies used in motion control systems require some type of interconnect device to transmit the signals from the cable to the motor or drive. Commonly used connectors include M12 and M8 connectors, which are circular connectors with a 12- or 8-mm locking thread used for sensors, actuators, Fieldbus and industrial Ethernet, primarily in […]
The basics of simulating radar signals with AWGs
Radar is quite simple in concept, but it becomes highly complex in actual implementation. Many decades passed between the time it was first envisioned and when useful working models emerged, which happened just in time to save England from total defeat in the 1940s. When it comes to testing radar, the situation has become easier […]
Electrical noise, Part 2: Additional perspectives
In Part 1, we looked at some facets of noise: sources, external versus internal (intrinsic) noise, and equations. Part 2 goes further into noise specifics. Q: What are some of the types of noise? A: It’s a long list. The same noise may have different names depending on the perspective of the person describing it, […]
Optocouplers, Part 2: Parameters and applications
Part 1 of this FAQ explored the basics of the optocoupler. This part looks at key parameters and some application examples. Q: What are the primary factors used when assessing an optocoupler? A: While there are many important factors, there are several which are noteworthy: isolation, current-transfer ratio (CTR), linearity (for analog use), and speed. […]
So what’s all this compound semiconductor wafer stuff?
David Danzilio from Wind Semiconductor sat down with us to explain some of the basics behind fabricating wafers in the compound semiconductor area. Compound semiconductors have a lot of commercial applications in optoelectronics. Many have a direct bandgap that makes them efficient light emitters. (As a quick review, the band gap is called direct if […]
