AGV Mobile Robot

Overview

The AGV mobile robot is an autonomous load carrier for intralogistics, moving totes, pallets, and racks between stations without fixed guide paths. A differential drive layout with two centrally mounted wheel modules lets it rotate in place, while swivel casters at each end carry the load. Onboard LiDAR mapping and SLAM let it localize against the building rather than floor markers, so routes can be reconfigured in software. A signal tower and touch panel report status, and a certified safety scanner slows or stops the robot when a person enters its field.

Construction

The vehicle is built on the Chassis, a welded steel base frame with bolt-on covers and a compliant safety bumper around the perimeter. Two Drive Module units provide propulsion: each pairs a geared BLDC wheel motor with an encoder and a local field-oriented controller. Each drive module rides on a sprung Suspension Arm rocker that keeps the wheel loaded on uneven floors, and unpowered Swivel Caster units at the front and rear share the load.

Energy comes from the Battery Pack, a 10S6P Li-ion array with an integrated BMS and pack fusing; the robot returns to its dock and mates the Charge Contacts plate automatically when charge runs low. The Navigation Compute module runs SLAM and path planning on a navigation SoC alongside a real-time safety MCU, fusing data from the Sensor Suite of navigation LiDAR, cameras, ultrasonics, and the certified safety scanner.

Payload handling is done by the Lift Module, a leadscrew-driven scissor deck with powered transfer rollers that raises a load off a stand or hands it to a conveyor. The Motor Driver Board supplies the high-current drive stage, and a wireless Wireless Comms Board keeps the robot in contact with the fleet manager for traffic and task assignment.
