In this playlist we have tried to show the process of developing a solution, by implementing each step, making a mistake, arriving at a solution and improving on this solution. Aligning to a wall is a useful concept in many robotics competitions and generally at different STEM problems. It shows a way to use two sensors at a time to get the robot position in space and take decisions based on this data,
This playlist presents a complex attachment that performs many tasks at once. The idea is for the robot to go out of base as few times as possible and once outside the base of FLL,WRO fields to accomplish as many competition tasks as possible. This attachment uses rubber bands and number of interesting and carefully places levers and axles. It would be difficult to use the attachment directly as it is for other missions, but it gives nice, interesting and valuable ideas on robotics attachments.
