Robot, Mechanical Dog
Part of Tamiya's Robocraft series, this four-legged mechanical dog with various speed controls walks by transferring motor revolution to reciprocating motion via crank and linkage rod. Main body and legs are made of transparent yellow parts to allow viewing of internal mechanisms. Construction is simple as parts can easily be attached with screws. Wiring has also been made simple. Clear switch with yellow transparent parts adds a cool, futuristic look.
Kit lets you become familiar with the mechanics of the dog's movement. All the parts needed to construct a mechanical dog are provided. Assembly and wiring have been made simple. 4 types of strides can be selected by changing the position of the holes on crank. Put this together with 2 types of gear ratios and you've got an 8-speed puppy. Cross link rods to make movement even more fluid and real. Gripping parts at the end of each leg to change position according to speed for smooth movement. Run on flat, smooth surfaces.
Requires one AA battery (not included) with a continuous running time of 2 hrs. at low speed/1 hr. at high speed.
