Police in US' Ohio fired Knightscope's K5 robot after 10 months for being useless and just rolling around a parking lot. The robot, equipped with 360-degree cameras and two-way emergency communication system, failed to arrest anyone, issue a fine or spot an incident requiring human police response. Knightscope even agreed to refund ₹57 lakh of the robot's total ₹1.21-crore cost.
