This is the beautiful version of the robot. :) It is more likely for having fun, than use it for competition. It have beautiful front that is not very useful for a competition, due to larger attachments, but it is a little bit more stable than the "uglier" and smaller version. :)
This robot is very low, relatively compact and very hard to control. To move as desired it must carry heavy attachment between its front tires. It also needs often clearing of its rear balls and the beads where they are positioned. Ones that is done the robot becomes pretty accurate. If you change the front tires with tires that have higher grip than the ones in the Spike set it becomes precious. Spike Prime Tires don't have grip but looks good. :)
It is ideal to learn how to control robots in real world applications where nature plays bad jokes on the engineers.
The two color sensors look up so it can see the attachment control parts, so it decides what part of the program to run. It have only one attachment motor with only 1 attachment element - 28 Teeth and 4 holes Gear.
