Micro-development drone autonomously navigates tight spaces
Robot and drone perception systems provider ModalAI has released two new products designed to help developers create smaller, smarter and safer robots and drones quickly and easily.

The VOXL CAM perception engine is a state-of-the art, fully integrated robot perception system. The credit card-sized VOXL CAM powers the Seeker micro-development drone , the company's newest and smallest drone to date, which is offered as the world’s first micro-development drone optimized for development of both indoor and outdoor autonomous navigation.

The VOXL CAM is an all-in-one compute and perception engine designed to make it easier to develop smaller, smarter and safer drones, robots and Internet of Things (IoT) devices with GPS-denied navigation, depth mapping, unmanned aircraft systems (UAS) flight control and cellular connectivity.

“The VOXL CAM platform provides smarter perception and safer navigation for autonomous devices beyond drones," says Chad Sweet, CEO, ModalAI. "For commercial and industrial developers and researchers who want powerful perception and autonomy, the VOXL CAM’s small form factor and modularity make it easy to mount onto drones, robots and wearable IoT devices. It condenses the computing power of seven PCBs and four concurrent image sensors into one compact, modular platform.”

Built on the company's VOXL Flight Deck drone development platform, the VOXL CAM is a single printed circuit board (PCB) that easily attaches to robots, drones or IoT devices to activate autonomy for a breadth of applications. The VOXL CAM perception engine includes the integrated Qualcomm Snapdragon 821 chipset, which enables GPS-denied navigation, depth mapping, object detection, obstacle avoidance and Simultaneous Localization and Mapping (SLAM).

The VOXL CAM perception engine has four image sensor concurrencies onboard, including:

  • Time of flight (ToF) for indoor depth mapping
  • Stereo pair image sensors for outdoor depth mapping
  • Tracking image sensor for Visual-Inertial Odometry (VIO) localization

It pre-integrates a PX4 drone flight controller, the company's Flight Core. In addition, it has three onboard inertial measurement units (IMU) and a barometer for controlling flight height.

The Seeker micro-development drone has a small form factor and enhanced visual capabilities, making it optimal for drones to safely and autonomously navigate tight spaces
