These innovations enable real-time facial recognition processing, enhancing security and ensuring safety. However, mobile robots are commonly employed in surveillance systems to handle risky tasks that are beyond human capability. In this paper, we present a prototype of a cost-effective mobile surveillance robot built on the Raspberry PI 4, designed for integration into various industrial environments. This smart robot detects intruders using IoT and face recognition technology. The proposed system is equipped with a passive infrared (PIR) sensor and a camera for capturing live-streaming video and photos, which are sent to the control room through IoT technology. Additionally, the system uses face recognition algorithms to differentiate between company staff and potential intruders. The face recognition method combines high-order statistical features and evidence theory to improve facial recognition accuracy and robustness. High-order statistical features are used to capture complex patterns in facial images, enhancing discrimination between individuals. Evidence theory is employed to integrate multiple information sources, allowing for better decision-making under uncertainty. This approach effectively addresses challenges such as variations in lighting, facial expressions, and occlusions, resulting in a more reliable and accurate face recognition system. When the system detects an unfamiliar individual, it sends out alert notifications and emails to the control room with the captured picture using IoT. A web interface has also been set up to control the robot from a distance through Wi-Fi connection. The proposed face recognition method is evaluated, and a comparative analysis with existing techniques is conducted. Experimental results with 400 test images of 40 individuals demonstrate the effectiveness of combining various attribute images in improving human face recognition performance. Experimental results indicate that the algorithm can identify human faces with an accuracy of 98.63%.<\/jats:p>","DOI":"10.3390\/jimaging12030107","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T08:51:57Z","timestamp":1772441517000},"page":"107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development of Surveillance Robots Based on Face Recognition Using High-Order Statistical Features and Evidence Theory"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0882-0057","authenticated-orcid":false,"given":"Slim Ben","family":"Chaabane","sequence":"first","affiliation":[{"name":"Computer Engineering Department, Faculty of Computers and Information Technology, University of Tabuk, Tabuk 47512, Saudi Arabia"},{"name":"Laboratoire de Robotique Intelligente, Fiabilit\u00e9 Et Traitement du Signal Image (RIFTSI), Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs de Tunis (ENSIT)-Universit\u00e9 de Tunis, Tunis 1008, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-8524-8761","authenticated-orcid":false,"given":"Rafika","family":"Harrabi","sequence":"additional","affiliation":[{"name":"Computer Engineering Department, Faculty of Computers and Information Technology, University of Tabuk, Tabuk 47512, Saudi Arabia"},{"name":"Laboratoire de Robotique Intelligente, Fiabilit\u00e9 Et Traitement du Signal Image (RIFTSI), Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs de Tunis (ENSIT)-Universit\u00e9 de Tunis, Tunis 1008, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9353-7605","authenticated-orcid":false,"given":"Anas","family":"Bushnag","sequence":"additional","affiliation":[{"name":"Computer Engineering Department, Faculty of Computers and Information Technology, University of Tabuk, Tabuk 47512, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hassene","family":"Seddik","sequence":"additional","affiliation":[{"name":"Laboratoire de Robotique Intelligente, Fiabilit\u00e9 Et Traitement du Signal Image (RIFTSI), Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs de Tunis (ENSIT)-Universit\u00e9 de Tunis, Tunis 1008, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,28]]},"reference":[{"key":"ref_1","first-page":"96","article-title":"Cyber policy for monitoring and regulating cyberspace and cyber security measures for combating technologically enhanced crime in South Africa","volume":"6","author":"Ezeji","year":"2024","journal-title":"Int.
