This is my first effort at a robotic arm. Except for the gripper, these are all ‘off the shelf’ standard parts: 5 servo motors, 3 U-brackets, and 4 servo motor mounts.
The motors are controlled by a Veyron Servo Driver. Notice that all of the motors appear to be moving at the same time as the arm travels from one position to another. Also, once the main program communicates instructions to the controller, the main program is free to perform other tasks even while the motors are turning. This non-blocking synchronization would be very difficult to program using the PWM pins on an Arduino or Raspberry Pi.
I signed up for Bluehost 2½ years ago for a 3 year subscription at the rock bottom price of about $3.00 per month, paid in advance. I suspect they pack their servers with hundreds of websites and mine can really slow to a crawl. But, for someone who wants to learn about web development and has no plans to make money at it, the price cannot be beat.
I rarely need any support from Bluehost, but my site was recently hit by a malware attack. I now have something to say on the subject of: Does Bluehost suck?
The shortcut navigation pane in Outlook allows shortcuts to folders on the local computer. By default, however, Outlook displays an annoying security warning dialog box when the link is clicked. This article explains the registry settings needed to disable the dialog.
