It’s not uncommon for video viewers to make suggestions to projects and since this entire project was based on viewer demand I’ve once again listened to some input. YouTube viewer Pete Prodoehl<\/a> suggested that I use the DRV8835 Dual Motor Driver Carrier<\/a> from Pololu instead of the motor driver shield that was using. I ordered one from Pololu and two days later it arrived in the mail. In this week’s video I removed the old motor driver and installed the new one which takes up less that half of the space the other one did. This makes more room on the perfboard so I decided to mount the battery in the available space.<\/p>\n

Another suggestion from YouTube viewer cfavreau<\/a> was to use a 5 mm LED as a low friction tail for this little tail dragger robot. I’ve since installed one.<\/p>\n

Thanks guys!<\/p>\n

Here’s a parts list for that parts I’ve used so far. They can be purchased from Pololu<\/a>.
