Watch youtube trailer for next season in slow motion to get an idea of what type of attachments will be needed for next season. We think it will be great to design a new bot specifically for this season rather than using our bot from last season for couple of reasons 1) Last year bot was bulking and had hard time moving it within narrow spaces. 2) Attachments were bulky to move around the board. So this year we think we will have attachment prebuilt into the bot and try to accomplish most of the mission with one single attachment. After viewing the video we felt that we need linear actuator to move up and down and tilt motion of forward and backward to accomplish most of the task. Mission requiring pushing or pulling can be accomplished by the bot itself. We may need a collector attactment to gather all the energy canisters spread across the board. Last year bot was moving slow, so this year we are planning to use the big Wheels to move faster on mat. Major change this year for us
