AI+ Robotics Practitioner (AT-420): Exam-Focused Prep

This course contains the use of artificial intelligence.

AI+ Robotics Practitioner (AT-420) by AI CERTs sits at the intersection of two fast-growing fields: artificial intelligence and physical robotics. This course, built by instructor Aseem Mankotia, delivers independent, vendor-neutral companion preparation for the AT-420 credential. It is not a replacement for the official AI CERTs training-plus-exam bundle, but a focused way to build the applied knowledge the exam blueprint actually tests. Across twelve chapters you will work through every official AT-420 module, consolidated into nine exam-weighted domains: robotics and AI foundations, autonomous systems and intelligent agents, ROS 2 and simulation frameworks, deep learning and reinforcement learning for robotics, generative AI and NLP for human-robot interaction, applied use-cases and RPA, emerging technologies like humanoids and VLA foundation models, and AI ethics and safety in physical systems.

Every chapter pairs direct, exam-style explanations with a tabletop or architecture lab, with no physical hardware required. You will sketch perception-plan-act loops, design a ROS 2 node graph, plan a sim-to-real reinforcement learning pipeline for robot locomotion, spec an LLM-driven voice-control stack for a robot arm, build a use-case selection matrix for industrial and healthcare robots, and construct a robot-safety risk register. Aseem Mankotia structures each domain around real exam patterns: scenario-based questions, service and robot-type selection decisions, configuration choices, and the common traps that trip up candidates who only know the theory.

The course closes with a full-length practice exam simulation mirroring the real AT-420 format: 50 scenario-based multiple-choice and multiple-response questions, a 90-minute timer, and a required minimum score of 70 percent (35 out of 50), plus a time-management strategy session so you walk into exam day with a clear plan. Whether you are a robotics or mechanical engineer, an AI/ML specialist, a systems integrator, or a student entering the physical-AI field, this course gives you a structured, practical path to master the AT-420 domains alongside the official AI CERTs training.

AI content disclosure: This course was produced with the assistance of artificial intelligence tools. Lecture narration is AI-voice generated, and lecture scripts, slides, and practice questions were drafted with AI assistance, then reviewed and curated by the instructor for technical accuracy and alignment with the official AT-420 exam guide.
