With robotaxis still a distant dream, lidar makes itself useful The promise of self-driving cars and robotaxi fleets once seemed just around the corner, but reality is setting in. Makers of the underlying technology are pivoting to more realistic ways of making money in the here and now.

Do explanations for data-based predictions actually increase users' trust in AI? In recent years, many artificial intelligence (AI) and robotics researchers have been trying to develop systems that can provide explanations for their actions or predictions. The idea behind their work is that as AI systems become more widespread, explaining why they act in particular ways or why t...
