Live Blog

+++ wrap-up .... Sun. 20 Sept. 2015 +++

Sorry, all, we had focussed on the mission ops and not really maintained our live-blog well. We hope that many of you were able to join here: our live-webcast on youtube, which was actually up-to-date all times.. 

So, INTERACT was a big success for us. We have demonstrated our mechanical assembly task from space and performed some science acquisition run's on INTERACT's second protocol. While andreas needed more than 40 minutes for the first connector placement task, a second run later in the evening only required 10 minutes! We found out, in our data-logs that we had recorded, that the first run featured a very large time-delay suddenly. Andreas had already mentioned this on the voice-loop and indeed during mission ops we have seen a significant delay on the robot's motion, even compared to what we could see on the NASA video cast from ISS (and that one is already usually 5- 6 seconds late). So while we had anticipated a delay of only 0.8 seconds on the Ku-Fwd link that we used, we suddenly saw 12 seconds (!) 10 minutes within the first run, just when Andreas actually wanted to start the peg-in-hole connector placement task. It's incredible that he still managed to complete the task under these circumstances ! It's 14 x longer delayed than we had anticipated.

So we are very happy with our software, our control method for force-feedback and are very happy about all your very positive feedback that I (andre) received from so many of you that followed the experiment.

We had about 680 viewers live during the run and our recored live-stream was seen by 12.000 people already one day after the experiment ! Thank you so much for your interest and for following us. I hope you enjoyed the 'behind-the-scence' live-cast of the mission operations that you usually don't get to see. It certainly encourages us to do this again next time, to again let you be part of such exciting missions of humans, robots and Space !

 

 

+++ 18:17 - waiting... +++

Just some on-board activities have been changed. We're waiting to be up for our Protocol-1 run.

Here, Andreas will need to perform paired comparison tests to measure his stiffness difference thresholds.

 

+++ 17:40 - waiting for Andreas's inflight call ! +++

SOrry.. too busy here to run INTERACT. We had a big success ! Protocol-2 worked the first time and he placed the pin in about 40 minutes. We started a second run but got interrupted

 

+++ 15:00 - Haptic Joystick set up on ISS +++

Unfortuntely the delay has caused our Science runs to be shifted to the back. However, in the meantime our Joystick is set up. Shortly, we will be repeating the SW installation on our real-time computer since we couldn't confirm successful installation in the last run. Very very likely at 16:10 we'll go straight into Protocol-2

 

+++ 14:00 - getting there... +++

Andreas set-up the cables for our Haptics equipment on-board 

 

+++ 13:35 - still setting up - +++

We'll try to push the Space-to-Ground video stream now also into our Webcast, since we just got approval from the Flight Director to do so. So if you follow our webcast on youtube (ESA Telerobotics Channel) you'll be directly seeing the space-to-ground video of Andreas... 

 

+++ 13:15 - Andreas started the setup +++

Unfortunately we're getting a little delayed here, since Andreas needs to swap to another worksite for the installation of our equipment.. I hope we can keep our Protocol-1 run still in the allocated slot at 14:00 but it looks difficult.

 

 

+++ 07. Sept. 2015 :: 10:34 :: Starting of INTERACT Space Experiment +++

Good Morning ! We're starting up !

Just heard exciting news this week-end. Our Satellite Link (Ku-Forward) has some issues that cause packets to be re-sent every time.. Difficult. But we decided to go ahead, trusting that our Software is robust even to this. But we didn't have a chance to test it. Fingers crossed !

So after all, we will really explore the unknown... Stay tuned also to our webcast, which this time will have a presentor that sometimes will highlight what's going on. 

At 11:00 we'll start with a small presentation about the experiment which we will stream as well. Then we'll be back live from 12:00/12:30 when the on-board operations are due to start...
