Surveyor SRV-1 Blackfin Robot
Open Source Wireless Mobile Robot with Video for Telepresence, Autonomous and Swarm Operation
Designed for research, education, and exploration, Surveyor's SRV-1 internet-controlled robot employs the SRV-1 Blackfin Camera Board
with 1000MIPS 500MHz Analog Devices Blackfin BF537 processor, a digital video camera with resolution from 160x128 to 1280x1024 pixels, laser pointer or optional ultrasonic ranging, and WLAN 802.11b/g networking on a quad-motor tracked mobile robotic base.
Operating as a remotely-controlled webcam or a self-navigating autonomous robot, the SRV-1 can run onboard interpreted C programs or user-modified firmware, or be remotely managed from a Windows, Mac OS/X or Linux base station with Python or Java-based console software. The Java-based console software includes a built-in web server to monitor and control the SRV-1 via a web browser from anywhere in the world, as well as archive video feeds on demand or on a scheduled basis. Additional software support for the SRV-1 is also available by way of RoboRealm machine vision software
, Microsoft Robotics Studio
, and Cyberbotic's Webots

- Third-party Software Support:
- RoboRealm - http://www.roborealm.com/help/Surveyor_SRV1.php - The SRV-1 can now be directly controlled from RoboRealm, a very popular Windows-based machine vision software package for robots. The RoboRealm extensions for SRV-1 allow creation of scripts that combine image processing on live video feeds from the robot, e.g. color filtering, blob detection/tracking, edge detection/outlining and feature extraction, with decision processing and robot motion control, making it easy to create behaviors such as object location and tracking, obstacle avoidance, motion detection, notification, etc, with a web interface, and control can be scripted from C/C++, Python, Java, C#, Lisp, Visual Basic, WScript and COM through the RoboRealm API.
- Microsoft Robotics Studio - http://www.surveyor.com/MSRS.html - Drivers for the SRV-1 in Microsoft Robotics Studio are now available. MSRS is a Windows-based environment for academic, hobbyist and commercial developers to create robotics applications across a wide variety of hardware. Key features and benefits include: end-to-end robotics development platform, lightweight services-oriented runtime, and a scalable / extensible platform.
- Webots - http://www.cyberbotics.com - SRV-1 support is now included in Webots mobile robotics simulation software. Webots provides a rapid prototyping environment for modelling, programming and simulating mobile robots under Windows, Mac OS/X and Linux. The 3D modeling and physics are outstanding.
