This smart hybrid crab crawls on solar energy when the sun shines. It can also run on batteries when there is no sunlight. First build your Crabot and then watch it 'crab' sideways! Build the crab and watch it scurry around. With this construction kit you can make your own crab robot. The crab runs on solar energy. If there is no sun for a while, the crab runs on battery energy. Please note: this is a French and Dutch version!
