About this Robot Arm:
This robot arm was an experiment to see if we could make a basic robot arm, with simple, but effective materials. As we are not set up for putting together something industrial, and we much prefer not having to resort to kits, or 3D print, we decided to look locally for materials that would be rigid enough to make our new robot arm.
The experiment, is because one of us has longed to build a six wheeled bomb disposal type robotics system for decades, but has never had the resources to do so. If we were going to make it a reality, we would have to know we could make a decent robot arm, with a good end effector, before setting about building one.
This arm is made of simple rigid aluminium from B&Q (superstore). We have manually attached servos, and connected certain joins with some Meccano angle pieces. Each moving joint has two servos, with the intent of running them opposite to one another. The end effector is attached using a single servo, and opens and closes with another one (one a clutch). The servos are large, RC, high torque, metal geared units.
The arm uses simple PCB stand-offs, to maintain some rigidity, and it’s remarkably effective. it remains to see what the final code will look like, or the base when it’s built. We also do not know yet whether this will be used on the six wheeled vehicle, or whether it will remain a prototype.
