Dusty Robot Vacuum Cleaner By Thames & Kosmos

Build your own robotic vacuum cleaner for your desk! Dusty has ingenious mechanical sensors that prevent it from falling off the table, getting stuck or crashing. Dusty also has a great personality, changing its facial expressions from happy when it's cruising on its cleaning mission to befuddled when it encounters an obstacle. Transparent parts let you peer deep into its mechanisms. Comes with 132 pieces and a 52-page manual with 2 experiments. For ages 8-11 with help, or ages 12 and up on their own.
