Making your own robots and remote-controlled cars is a lot of fun, however in some areas the cost of a decent chassis can put the project out of reach. To solve this problem, Instructables member tominjose has used inexpensive PVC piping as the chassis for his 4WD with great success.
Each motor fits comfortable within the pipe diameter, and the design of the structure also allows much of the wiring to be hidden from the elements. The four motors are controlled with external driver ICs, and the addition of a Bluetooth slave receiver module allows remote control of the robot from an Android device using a free app. A neat demonstration is provided in the following video:
A great project with a lot of potential - and you can find the instructions and sketch in the Instructable page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
If you're looking into starting with Arduino and motor control - check out our new HBRIDGE: DC/stepper motor shield. Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page.
