RobotShop describes the same kit family as 6.5 in \/ 165 mm diameter class - FLAG, 163 x 149 mm (Pololu) vs 165 mm diameter (RobotShop) are not identical, use Pololu 163 x 149 x 70 mm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e General-purpose mounting holes\/slots for electronics; designed around the Pololu Romi ecosystem (motors\/wheels\/caster in kit).

FLAG\/CONFLICT: Pololu 3D-model note says the assembled model includes a front ball caster that is sold separately from the Romi Chassis Kit - conflicts with the kit description saying a ball caster is included. Do NOT promise a second\/front caster; list only one ball caster and verify with Pololu before listing. FLAG: motor gear ratio, voltage and speed NOT given on the fetched Pololu spec page - do NOT copy Romi motor specs from another kit.\u003c\/p\u003e","brand":"RoboCircuit","offers":[{"title":"Default Title","offer_id":67844484104506,"sku":null,"price":11060.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/4158\/2906\/files\/0J7260.600x480.jpg?v=1793367432","url":"https:\/\/robocircuit360.com\/products\/pololu-romi-chassis-kit-black-differential-drive-robot-base-with-motors-wheels-and-caster","provider":"RoboCircuit","version":"1.0","type":"link"}
