Case study: Delivery robots
Lightweight and efficient power modules extend delivery routes and save space to carry more goods
Customer’s challenge
Last-mile consumer delivery of groceries, take-out food and online consumer items is the mission-critical task of these autonomous robots. While payloads vary in size and weight, these robots typically have long run times and are typically powered by 48V to 100V batteries. Delivery robots are equipped with a variety of sensors, cameras, and GPS technology to navigate their surroundings safely and efficiently. These robots depend on batteries, which pose a challenge for their operational range. The key goals were:
- Extend range and run time
- Compact and lightweight solution to save space
- Supporting a variety of point-of-load voltages
The Vicor solution
Vicor high-performance power modules reduce space and weight on board, increasing space for sensors and navigation systems and enabling delivery robots to carry larger loads and objects. The high efficiency levels of Vicor power modules increase operating time allowing them to reach more distant destinations safely.

Power delivery network
The DCM™ converter series fits the needs for this class with operation from 43 – 154V input. The DCM3623 enables a regulated 24 or 48V distribution from the battery for servo drives, other payloads and downstream converters. The DCM3623 provides 240W of power at 90% efficiency from a 36.38 x 22.8 x 7.26mm package. With a 24 – 48V rail established, ZVS buck or buck-boost regulators can typically be used to power lower voltage rails.
