Motion sensor The motion (or distance) sensor for the current WeDo kit. These sensors give students the opportunity to experience how robots sense the world around them. Although it might not be possible to change the arrangement of computers and workstations, some space is necessary for building the projects while linked to the computer by USB cable.Both versions of the WeDo kit (2.0 and 1.0) come with two sensors.If students are working on projects over several lessons, then storage for partially completed projects will be necessary as well. Storage will be necessary for the kits.It’s nice to have a projector attached to the teacher’s computer to display the software and activities while teaching.The LEGO Education WeDo Software is available to download here.
