We just completed our most complex EV3 robot so far! Let's review what we have learned.
Being a bipedal robot, Grunt was our first departure from tank-style locomotion. We made a robot that walks instead of drives and learned about the simple walking mechanism that allows Grunt to shuffle about. Next, we discussed some of the aspects of the exterior design that help develop Grunt's character and give him the appearance of an alien creature from a distant planet. We revisited cams and gear ratios, then introduced a completely new mechanism, a clutch-like locking axle; Grunt's mechanical design demonstrates the usefulness of this mechanism for creating two different motions, one delayed behind the other, using only one motor. This is a great concept to have in your toolkit when you design your own smart robot.
We made our most sophisticated program yet, a...
