The final Phase 2 robot design followed our Phase 1 robot proposal and further develop the robot arm and refine the hopper. Initially, the design was to spear and flip loops into a top hopper on the robot. However, as we started to consider collecting loops placed in any orientation, the robot arm design soon [...]
In anticipation to collect loops that were placed in any direction, a double claw robot was built. This design was later discarded due to concerns with its efficiency and maneuverability, but the robot was such a massive and impressive creation, its design concept is documented here for the record. The Claw Robot Design was divided [...]
Different robot designs were tested. This is a video of how well our robot ventured off the base ramp.
This is a video on testing the robot drivetrain using Bluetooth remote control.
With the newly arrived LEGO pieces, we swap out the dark gray bricks on the ridges, and finished them with all the light gray pieces we got. With the field finally put together last week (still without the side panels), this was the busiest day with some real design progress! With Brian back from camp [...]
The Robot Proposal is divided into couple design components: End Effectors: fork flipper and cable claw Motors: 2 Power Function and 3 NXT motors Drivetrain: rear wheel drive, 2 wide flat rubber tires, 1 tank tread, 2 front skis Sensors: EOPD, compass, ultrasonic sensors Accessories: IR Link, Magnets, Video Camera

1 Comment »When climbing over the crater wall, we found that we couldn’t make our robot too tall from the ground or it would tip. With a shorter robot, there was less ground clearance and the robot would get stuck on the crater wall. Tank treads would have been good to climb over the crater but they [...]
The Moonbots mission challenge requires the robot to run on the LEGO mats as a rough terrain and the robot has to go in and out of craters. Therefore, we first built a segment of a crater and use it to estimate the total size of the crater.
Today we finally started the conceptual designs for robot drive-train, ways to pick up the loops, plus using sensors to navigate. Each one of us picked a task to work on.
