The bot navigated successfully back to the melthole using dead-reckoning and then used a visual homing algorithm to lock on to a blinking light and rise up the meltole. This was very exciting moment for all of us. The images below were taken by the upward looking camera while coming back to the melthole.
First long drive of the bot
The bot drove to West-Lobe Bonney glacier ablation stake. The primary objective was to exercise and test the full navigation capabilities, and get the procedure down for performing missions and collecting data. The stake was expected to be about 390 m from the melt-hole. We did not find the stake but saw the object below (that was put in by Peter and Maciej for reference) in the images taken by the forward looking camera. We also got some great images of the under-side of ice.
