AR4 MK4 Hardware Kit

$429.00

This combo kit provides all the primary structural and hardware components to build the robot. You do need to purchase the motors and drivers factory direct from Stepperonline. To keep the AR4 project as low cost as possible I dont mark these up, add any taxes, tariffs or additional shipping fees - purchasing the motors direct keeps the robot cost as low as possible. You also need to 3D print a number of the covers and spacers - this also keeps the project cost as low as possible not having to pay for injected molded components.

This kit includes all bearings, belts, pulleys, sprockets, chain, shafts, pins, machine screws, and set screws required to build the AR4 MK3 robot.

Kits are shipped within 1 to 2 business days.

Returns on assembled or partially assembled kits can not be accepted. All other returns are subject to 25% restock fee. Any credit card orders canceled prior to shipping subject to $36 processing fee.

Please review assemlby manual and bill of materials. Electronic components, plastic covers and spacers are not included with this kit.
