About this Robot Arm Tutorial The robot arm is probably the most mathematically complex robot you could ever build. As such, this tutorial can't tell you everything you need to know. Instead, I will cut to the chase and talk about the bare minimum you need to know to build an effective robot arm. Enjoy! To get you started, here is a video of a robot arm assignment I had when I took Robotic Manipulation back in college. My group programmed it to type the current time into the keyboard . . . You might be also interested in a robot arm I built that can shuffle, cut, and deal playing cards. Degrees of Freedom (DOF) The degrees of freedom, or DOF, is a very important term to understand. Denavit-Hartenberg (DH) Convention The Robot Arm Free Body Diagram (FBD) The Denavit-Hartenberg (DH) Convention is the accepted method of drawing robot arms in FBD's. 4 DOF Robot Arm, three are out of plane: 3 DOF Robot Arm, with a translation joint: 5 DOF Robot Arm: (image credit: Roble.info) Spherical Robot Arm.
Search results for: 'claw' - VEX Robotics. Robotic Claw. Description: This robotic claw is a step up from the classic. The MKII takes everything you loved about the standard robot claw from DAGU and makes some significant improvements! Just like the classic claw, they are made from metal and are pretty heavy-duty, but the MKII also features brass sleeves in the joints which make them more rigid and less likely to come loose.
The claw opens to about 2" and depending on the servo motor used, it can pick up some relatively heavy objects. The new spring-loaded clutch helps protect your servo gears from damage and also increases the gearing to 2:1, allowing the servo to act over its entire range and provide more gripping power! These also have a mounting plate on the bottom which accepts standard spacing found on servo mounts (the extra bits that come with our servo motors). Documents: Replaces: ROB-10332.
