Professional Smart 4WD Metal Robot Car Chassis Kit with 97mm Mecanum Wheels, DIY RC Robotic Moving Platform,for AGV, School Eduactional Science Kits, Remote Control Robotic STEAM Model Experiment

Goes together easy and the assembly is basically self explanatory

This is a solid aluminum chassis kit. It contains the chassis itself (3 pieces extruded aluminum, hardware, and brackets for the motors.) plus the motors and the wheels. Motors are 12v, 360RPM, 4.8W, model 37gb-520-30f. Wheels are standard 97mm Mecanum. Also included are wheel couplers, motor wire pigtails, and a 2x 18650 battery holder. All of the parts are solid and for the price, it’s a good deal.But I am knocking it down one star to 4, because of documentation.Namely, there is not one single picture of the kit assembled correctly in this listing. So if you buy this kit, do NOT use the pictures in the listing to assemble. The order wheels is incorrect. There are 2 directions of Mecanum wheel, L and R. They need to be alternated L-R when installed, so that when viewed from above, the small roller wheels make an X pattern. The photos in the listing all show the L wheels on one side and the R wheels on the other. This is WRONG and a robot assembled in this fashion will not roll correctly. (I have included a picture of the chassis assembled correctly.) This is probably why the previous reviewer had problems getting the kit to roll.Even with the poor documentation, this kit is a very good deal. The parts are awesome and if the listing and documentation were better this could be a 5 star product.

easy to assemble strong motors but thats where it ends wheels are completly useless no traction at all they just spin and does not steer at all. very dissapointed i wasted most of my budget on this and now my project is just a papper weight
