This is team 997's Climber Bot. It has two pairs of pistons, and a linear actuator to move the inner pair forward and backward. I does not currently have any other method of movement, although a modular drivetrain "attachment" is planned and in the works. There is also going to be a "disc dumper" attachment on the middle pair of pistons. This dumping phase of the climb is simulated as a dry run in the video. You may notice that there is a lot of rocking, and that the robot is bashed against the pyramid. This will be alleviated by another pair bumpers on the chamfered front of the 'bot. Any questions, comments, or critiques? Please feel free to post!
