Today, we will revisit the older hydraulic arm tutorial which broke in the change from R13 to R14, we will rig up a robotic arm from scratch. This time we’ll also put together the claw and wrist setup instead of ending in a stump, plus add in tubes for hydraulics that automatically stick to the proper spots. We’ll be using lot’s constraint tags, spline IK tags, and one very important IK tag.
In part one we will setup the mechanics for the arm and claw, building enough geometry to give us the proper visual queues to know we’re making it correctly. Also, we will be paying close attention to priorities of out rig to weed out order of operations mistakes.
In part two we’ll add in the pistons for the hydraulics, setup the tube system for linking different parts of the robot, and add a control for moving the base around. At the very end we’ll use this rig as raw material to put together an entire bipedal robot rig.
