1 Tele-Robotics Demonstration (Rover Tele-operation) JUSTSAP-PISCES Symposium 2008 November 11, 2008

2 2 Agenda Demonstration overview Technology and Products of remote control platform Let s enjoy Rover Tele-operation Time Trial

3 3 Demonstration overview Let's experience the effect of "latency cancel technology" for teleoperation. Rover Wireless LAN Access point Internet simulate PC Operation PC PISCES Simulate data transmission delay in Internet InternetInternet Japan/US A

4 4 Technology and Products You can develop advanced remote control system easily and at a low cost. TelePresence over IP Platform for the remote control system which requires the digital video transmitted by wireless LAN and internet.

5 5 Technology and Products Advanced remote control system Operation from everywhere of Internet available places High operativity using Motion JPEG video Easily and low cost I/F for using COTS equipments (WirelessLAN, Internet, PC, game controller, etc.) Software Library for easy system development by users All-in-one platform for video-based remote control system

6 6 Remote control system using TPIP Video & Sound data Sensor data Control command data Sound data internetinternet PC controller Target System Wireless LAN card WireLess LAN Access point Bidirectional WireLess LAN IEEE802.11a/b/g NTSC Camera Sensor Microphon e Speake r Motor control input output TPIP Unit TPIP Library

7 7 Minimization of Video transmission delay NTSC video capture JPEG Encoder JPEG compression Wireless LAN IEEE802.11g 20Mbsp 15Kbyte(1/60) Decoder & rendering JPEG decode & rendering PC monitor Refresh Rate:60Hz VGA/QVGA 30fps NTSC Camera + Internet 33ms Processing time 20ms 6ms 20ms 17ms TPIP TPIP Total delay time 96ms 100ms Web Camera Total delay time500ms Network Camera VGA 15fps QVGA 30fps

8 8 High-speed image compression image compression 30 frames/sec. (NTSC -> Motion JPEG) No re-transmission Communication UDP/IP High-speed image rendering High-speed Motion JPEG decoding, image processing middleware ResolutionVGA(640 x 480),QVGA(320 x 240) Frame rate30 frame/sec Video transmission delayLess than 100ms Performance Minimization of Video transmission delay

9 9 Removal of Transmission delay influence 1sec delay 1sec delay moves during delay time 4km/h ex. walk 4km/h ex. walk 10km/h ex. model car 10km/h ex. model car Hawaii Japan 6sec? delay 6sec? delay EarthMoon Hawaii 2.8 m Moon Hawaii Moon 5700km 384400km 16.8m 6.6m 1.1m

10 10 received image captured at T received image captured at T corrected image view at T+ΔT Steering angle speed Image transmission delay ΔT Image transmission delay specify a red frame part by three data Point T T+ΔT Removal of Transmission delay influence

11 11 Correction of Transmission delay fluctuation Remove the video frame intervals fluctuation which degrades operativity without image buffering Delay timet1 Time Stamp t1=Time now -T1 Sendimage Receiveimage Displayimage A fluctuation by the transmission delay occurs display images at same interval by time stamps
