The Hexapod Explorer wooden model kit has 388 pieces and features a strong metal spring that powers the robot's walking action, and rubber band foot pads for better traction on smooth surfaces. This DIY model is rated Medium level with an assembly time of approximately 8 hours. The internal spring is wound with a ratchet key located on the belly. With a ratchet mechanism you don't have to hold the key while winding to prevent slippage—potential energy is stored with each twist, without slippage, until the spring is fully loaded. The Hexapod Explorer can traverse rough surfaces and even step over obstacles of 1-2 cm. Crank the model up, set it down, choose the desired speed using the dial on the Hexapod's head, then release the "go" switch at the rear to set the model in motion. You can change speeds at any time, either mid-run or on the next go. Number of components: 388 Estimated time of assembly: 8 hours
