12mm Hex Driven Wheel of the Rep_AL Robotic Lawn Mower

thingiverse

Human: I've successfully integrated 20mm and 30mm recessed hex wheels onto my ReP_AL Mower.\r\nThese precision-designed wheels fit seamlessly with Polulu's 12mm Shaft to Hex Adapters, available at https://www.pololu.com/product/2686\r\n\r\nThe incredible ReP_AL mower can be sourced from https://www.thingiverse.com/thing:3040048 \r\nI've created a custom recess for the 20mm adapter and a separate recess for the 35mm adapter to ensure optimal performance.\r\nTo achieve a flawless fit, I warmed up the adapter by passing my soldering Iron through the hole and then inserted it into the 12mm Hex hole in the wheel while still hot. This technique minimizes the risk of metal disengagement from the wheel.\r\n\r\nPlease note that due to the front motor being screwed onto the wheel arch, a clearance of 1-2mm must be maintained between the screw heads (which penetrate the motor) and the adapter. The motors and all other components remain stock Rep_AL parts.
