Stardate 2011.07.21 (Thursday) - Video Camera Arrives!

posted Aug 17, 2011, 6:24 PM by Anant Narayanan

Today we continued work on the rover design.  It now climbs the terrain ridges well, because it has most of its weight in the front, allowing it to tip over once the front reaches the top of the ridge. 

We also moved the competition board off the (soft) floor carpet onto a heavy table frame with a base layer of half-inch MDF (Medium Density Fiberboard) under the Lego baseplates.  This change made the competition terrain much firmer and improved the consistency of results.

Minyoung showed Rohit and Gabriel how to use data wires and variables to program the robot.  However, they ran into trouble since they were unable to run data wires into certain wait blocks.  They decided to simplify the programming approach to increase the chances of completion.

We also got the compact MUVI HD Video Camera with remote control from Amazon.  It is the kind used by skydivers and skiers and comes with a variety of mounting options including a bike and helmet mounts.  In our design, we mounted it on a rigid extension beam on the left side of the rover.  Next year (if there is one!) we will fix it on a gravity gymbal that allows the camera to face forward at all times, regardless of the up-down movement of the rover, especially while climbing ridges.
