Overview

The QBot 2e is built on a two wheel differential drive platform with built-in DC motors and sensors. It utilizes a wireless embedded computer to command motor velocity and measure the onboard sensors including bump, cliff, and RGBD. The embedded system also provides several I/O channels for interfacing additional digital and analog sensors. The integrated RGB camera and depth sensor are capable of capturing RGB image data and 11-bit depth data and transmitting the data at a high frame rate. The QBot 2e operates using a host-target structure. Controllers are developed on the ground station host using QUARC for Simulink®. Real-time code is downloaded from the host to the QBot 2e embedded computer and allows users to run, modify and monitor code remotely from the host. The controllers on-board the QBot 2e are open-architecture and fully modifiable.

  • Wide range of sensors included (bump sensor, wheel drop sensor, cliff sensor, 3-axis gyroscope, RGBD sensor)
  • Customizable with off-the-shelf sensors supported by QUARC, including digital (SPI, UART, I2C) and analog sensors
  • Low power on-board computer with Linux operating system for high-level, real-time decision making and task execution
