Sound-Off: How Do Collaborative Robots Spot Human Operators?

In a “speed and separation” manufacturing scenario, a safe distance must be maintained between a collaborative robot and a human operator. When the gap reaches below a specific threshold, the cobot then initiates a monitored stop. But how does the robot “see” the human?

Soft “Vinebot” Excels at Search and Rescue

Inspired by natural organisms like vines that cover distance by growing, researchers at Stanford University have created a soft, tubular robot that lengthens to explore hard-to-reach areas. The vine-like robot can grow across long distances without moving its whole body, which could prove useful in search-and-rescue operations and medical applications.

Sound-Off: How Do a Vehicle’s Imaging Sensors Filter Out Weather, Crosstalk?

A "Geiger-mode" lidar sensor sends out pulses at a high repetition rate (200 kHz), forming an image on the percent of pulses that return. The technology has been used by vehicle manufacturers to support collision avoidance, adaptive cruise control, and other Advanced Driver Assistance System (ADAS) applications. But how will factors like snow or another vehicle’s lidar impact a sensor's reading?
