First SRV1Console images from SRV-1 Blackfin Linux

We just captured first images from simple srv1 server application running on the Blackfin uclinux port. There's some corrupted frames due to character post-processing on the stdio console that we haven't been able to completely clear, but 50% of the frames are getting through intact. Here's a sample. Apologies for picture quality - lots of reflections from the afternoon sun:



Once the console issue is resolved, the next tasks are adding support for OV7725 (this was taken via OV9655), bumping the baud rate to work at full speed with the Matchport, and then porting various robot controls to our SRV_protocol, SRV_httpd and picoC interfaces. Lots to do, but this was an encouraging first step.

SRV-1 / SVS Blackfin Linux



We're making a push to bring our Linux support on the SRV-1 / SVS up to date. Details are found here -
      www.surveyor.com/cgi-bin/yabb2/YaBB.pl?num=1276379812

The basic plan is to migrate all of the SRV_protocol, SRV_httpd, and picoC capabilities to run under uClinux, thereby maintaining compatibility with our various Java consoles, labview-srv, Roborealm, etc. The main issue will be adding 2500kbps communication via the Matchport, but we think we have a mechanism to handle this, as the kernel now supports hardware flow control that is required by the Matchport. This project is a top priority and we hope to make significant progress in the upcoming weeks.

Fun with planes, parafoils and robots

Snowflake is a collaboration between Naval Postgraduate School and University of Alabama in Huntsville to develop single and multiple autonomously guided parafoils. The project, described in detail here, uses an Arcturus T-20 UAV to launch the parafoils and a Surveyor SVS-based robot with Inertia Labs Renegade base to autonomously locate the parafoils after landing.

We had the opportunity last week to view Snowflake field tests at CIRPAS McMillan Airfield. The Arcturus launched a pair of Snowflake parafoils from 3500-ft, and upon touchdown, the Snowflake controller transmitted GPS coordinates that were relayed to the robot. The robot then autonomously moved to the transmitted coordinates using a script written in picoC. We witnessed 3 successful UAV launch and robot retrieval cycles. Future tests will include drop of a smaller version of the Surveyor robot by parafoil.

Surveyor programming interfaces (API's)

There are several control options for the SRV-1 / SVS, and it isn't always obvious what approach might be best. Here's a summary:
  • SRV_protocol: this is the control interface we have provided since the earliest of our SRV-1 robots, and while we continue to add new functions, the core functionality remains the same - mainly ASCII-based commands to access motors, sensors, on-board processing, and system configuration. Through this interface, we directly support four different console programs as well as a variety of third-party and user-developed consoles:

  • SRV HTTP: this uses the browser as the robot control console, and generally works with smart phones as well as full-sized computers. Almost all of the functions accessed via SRV_protocol are available through the HTTP interface.

  • picoC: this is the onboard C-interpreter that enables programming the SRV-1/SVS for fully autonomous behaviors. Most of the SRV_protocol functions are available under program control with ANSI-C syntax.
There is another option of extending the firmware functionality by modifying source code. The firmware is hosted as an open-source Google Code project - http://code.google.com/p/surveyor-srv1-firmware/, with compiler toolchains found on our website - see http://www.surveyor.com/blackfin/#blackfin4.

miniSVS - a reduced footprint version of the SVS Blackfin stereo vision system

In response to a request from the GMU RoboPatriots for a more compact version of the SVS to fit their RoboCup robots, we shrunk the original SVS layout from 6" x 2.5" to 4" x 2.5" (100mm x 63mm). The new camera spacing is 2.25" (55mm), though for the RoboPatriots, the spacing isn't an issue, as they are running ribbon cables from Blackfin to cameras mounted elsewhere on the robot.



We are calling the new board the "miniSVS". In shrinking the board, we removed some functionality that the soccerbots didn't need, including FAN8200 H-bridge, antenna mount, laser pointer drivers, and SPI interconnect. In place of the SPI interconnect, we are using a pair of GPIO lines with a soft UART driver.



The basic assumption was that this board would be used with other motor drivers with serial or servo interface, though perhaps this configuration would be attractive to existing SRV-1 robot users. If that turns out to be the case and there is sufficient interest, we can look at adding back the H-bridge and laser drivers.



As with the full-sized SVS, the miniSVS does include interfaces to 8 timers (4 on each Blackfin) with 5V power and servo headers, along with low battery detect circuit.



Those who are interested in the miniSVS or variations should send us
an email, and we will consider adding this to our standard product list.

SRV-1 / SVS Blackfin HTTP functionality extended to support most SRV_protocol robot control functions -

The latest version of SRV-1 / SVS Blackfin firmware adds most of the SRV_protocol functions to the HTTP interface, enabling more complete robot control via a standard or mobile web browser. Motor control functions are provided for the existing SRV-1q PWM, the new SRV-4WD controller, as well as RC ESC controllers such as Sabertooth and pan/tilt servo interfaces.

Camera resolution and JPEG quality can now be set via HTTP. Also supported are the SRV-NAV gps, a/d, tilt and compass interfaces, generic I2C devices, SRV-1 vision processing functions, and laser pointer controls.

Using the SRV-1 HTTP interface is really simple. To test these, you can point your browser to
      http://robot-ip:10001/robot.cgi?____
where ____ represents the SRV_protocol function, e.g.
      http://robot-ip:10001/robot.cgi?V
will display the firmware version string

As before,
      http://robot-ip:10001/robot.jpg
will capture a new JPEG frame. We have also provided a simple webcam script using this capability.

Surveyor Robot Forum discussion with additional details is found here - http://www.surveyor.com/cgi-bin/yabb2/YaBB.pl?num=1265742063. Example code for a simple webcam interface is provided.

The new firmware has been posted to http://code.google.com/p/surveyor-srv1-firmware/

RoboPatriots humanoid soccer players for RoboCup using Surveyor SVS Blackfin -



The Autonomous Robotics Laboratory of George Mason University has fielded a team, RoboPatriots, for the RoboCup humanoid league, a prestigious international autonomous robotic soccer competition. RoboPatriots is one of only two teams from the USA that competed in the RoboCup humanoid league in 2009 (of 24 teams overall). The team is small and has never received any outside funding, so one of their goals is to present an inexpensive and robust robot platform that still competes well. In comparison, their competitor's robots generally cost 4-5 times as much.

As the team prepares for next year's competition in Singapore, they are developing tools for humanoid motion and path planning, vision-based localization, and multiple-robot coordination, as well as physical simulation software. The Surveyor SVS (stereo vision system) has proven to be a critical part of their robot architecture, acting as the brains and eyes of the robots.

2010 Robot Specs:
  • Team Name: RoboPatriots (Johnny 5, Newton, and Stephanie)
  • Height: 53 cm
  • Weight: 900 grams
  • DOF: 18 (5 DOF per leg, 3 DOF per arm, 2 DOF neck)
  • Motors: Arms and Legs (16): Kondo KRS-2555HV digital servos
  • Motors: Neck (2): Kondo KRS-788HV ICS Digital Servos
  • Computing Unit: RCB-4 from Kondo
