Versatility, durability and simplicity all in one box! The 7.2V Motor, Bracket and Wheel Kit (#570-00070) features lightweight and sturdy aluminum brackets which are specifically designed to make mounting the included 7.2 VDC motors a breeze. Each bracket is machined in-house at Parallax headquarters in Rocklin, CA. The brackets are machined from 6063 aluminum extrusion and anodized black for improved scratch resistance and aesthetic appeal.

High quality 7.2 Volt DC motors feature durable construction, and 100% all-metal gears that stand up boldly to rough terrain and abuse. The motors' top speed of ~310 RPM equates to a speed of approximately 6.6 feet/second (2.0 m/s) which is perfect for most medium- to small-size robotic projects. The included machined aluminum hubs solidly engage the 4 7/8 inch (12.4 cm) diameter wheels. The tread is molded directly onto the wheel and offers excellent traction on most common surfaces.

Giving your robot mobility has never been easier!
