Autonomous Mobile Robots (AMR)

AMR is an advanced technology robot used for various applications in diverse industries. AMRs are an advancement over automated guided vehicles (AGVs) with safety features and quicker execution.

In an AMR, the vision system plays a key role in moving the vehicle from one location to another autonomously. AMRs are developed using the latest vision technologies, such as 3D cameras, LiDARs, and sensors. 3D cameras are used to capture images while mapping the boundary of the designated path. AMRs can be used in various industries for the movement of objects from one location to another. For instance, warehouses, manufacturing plants, hospitals, supermarkets, etc.

AMR is run by a DC servomotor, which is selected based on the drive train calculation. It can travel at a speed of 2 m/s with a full payload, along with 2° gradability. We have designed this product with high speed and high ground clearance compared to our competitors’ products. The motor is powered by an LFP battery specially designed for 7-8 hours of continuous operation.

Insights into AMR Operations

The system is controlled by an IPC, which passes commands to the motor controller and Lidar to drive the system. The motor controller controls servomotors connected to wheels on both sides. The IPC is powered by a 12-volt power supply stepped down by a DC-DC converter from a 48-volt battery pack. The lidar, LED indicators, and buzzer are supplied with the same power supply. Once power is gained by LiDAR, it starts scanning an environment in 360° view to set up the boundary.

The scanned data has been sent to the IPC, where it uses the data to generate a map using the SLAM method. AMR will locate itself on the generated map and will navigate autonomously to the desired location. While moving along a path, if it detects an obstacle, it will stop at a safe distance with alarm indicators. AMR will resume its operation once the obstacle has been cleared from the path. Ultrasonic sensors are placed on the sides of an AMR for safety and to avoid collisions.
