What to Look For in a LEGO Robot Kit?
When purchasing a LEGO robot kit, there are certain features to keep an eye out for. The following criteria can help you in your search for the best Lego robotics kits:
Number of motors
Most smaller robots use one motor while more complicated models often require two or three motors. In general, larger sets come with at least two motors. High-tech additions including light sensors and infrared transmitters also need more than one motor to operate properly; these will usually include up to four separate electric components on top of the aforementioned mechanical parts. Microscopic projects may only contain a single electric component that runs off of batteries rather than electricity from a power cord.
Level of detail
This is important because it determines how much time and effort is needed to construct the kit. Sets with a high level of detail are more expensive and often require different tools in order to complete tasks, whereas sets that lack detail can be completed quickly without much hassle. * Number of pieces – This refers to how many Lego bricks come included in each set. More complicated models usually contain at least 500 or 600 blocks for constructing robots while simpler kits may only have 300-400 blocks due to their less detailed designs.
