Knightscope K5 Timeline

Knightscope acquired Event Risk, a national provider of security guards and executive protection services. The move extended Knightscope's offering beyond autonomous robots into manned security, allowing the company to pitch a combined human-plus-robot service to clients who require both physical response capability and autonomous patrol coverage.

An Ohio police department entered into a two-year agreement to deploy an upgraded K5 unit, becoming the first law-enforcement agency in the United States to sign a contract for the enhanced K5 Autonomous Security Robot. The police deployment marked a significant expansion of K5's client base beyond corporate and commercial settings into public-sector law enforcement support — though the robot's role remained limited to patrol and reporting, with no powers of arrest.

Knightscope announced a significant upgrade to the K5's autonomous navigation system, expanding the robot's operational envelope to cover larger and more complex environments than previous generations could manage. The upgrade was paired with an expanded sensor suite including additional LiDAR and sonar sensors, improving obstacle detection and route-planning fidelity.

Throughout 2024, K5 deployments occurred at a hotel in Louisville, KY; a casino in Kansas City, KS; and a storage facility in Richmond, CA. Active deployment locations spanned Arizona, California, Connecticut, New Hampshire, New Jersey, New York, and Texas, among other states, establishing the K5 as the most widely deployed autonomous security robot in the US by site count.

Knightscope completed a direct listing on the NASDAQ exchange under the ticker KSCP, raising capital to fund further K5 deployments and development of new autonomous security robot models. The listing came after several years of crowdfunding from retail investors via Regulation A+ offerings, which had generated significant public awareness of the company.

A K5 unit at the Washington Harbour complex in Georgetown, Washington DC fell down a set of steps and into a decorative fountain, coming to rest in about 60 cm of water. The incident attracted extensive media coverage and the robot — quickly nicknamed "DC Robot" on social media — became one of the most widely shared robotics stories of the year. Knightscope recovered the unit and the deployment continued. The incident highlighted that the K5, while capable of autonomous navigation, required carefully prepared environments without unexpected drops or obstructions.

A K5 unit patrolling the Stanford Shopping Center in Palo Alto, California struck a 16-month-old child, running over the child's foot and causing a minor injury. The incident prompted significant public debate about the safety of autonomous robots in public spaces and the adequacy of oversight. Knightscope conducted a review and the robot continued operating at the site. The episode became a reference point in discussions about liability, insurance, and regulatory frameworks for autonomous civilian robots.

Knightscope began its first commercial deployments of the K5 Autonomous Security Robot, initially at technology company campuses in Silicon Valley. The SAAS subscription model — approximately $7 per hour, with Knightscope retaining ownership of all hardware — was presented as a way for clients to add autonomous patrol coverage without the capital cost of purchasing equipment.

Knightscope, Inc. was founded by William Santana Li and Stacy Dean Stephens in Mountain View, California, in the aftermath of the 2012 Sandy Hook school shooting. Li and Stephens sought to develop technology that could help prevent mass-casualty events. The K5 prototype was introduced the same year: a tall, egg-shaped wheeled robot designed to patrol outdoor environments, collect sensor data, and relay it to human operators. The design was deliberately non-threatening and unarmed, intended to function as autonomous eyes and ears rather than any kind of enforcement mechanism.
