I didn’t program that behaviour…Īfter three runs, it breaks - the sensor/grabber module pops off, during the force of the grab. ![]() After it reverses, for no apparent reason, the grippers open on braking. It is a bit aggressive - and knocks the stand around, almost catching it in the grippers. ![]() I run the program, and find it suitably fun. Now to program it I again just followed the tutorial, getting into the swing of things. Unfortunately, I got no photos of the robot at this stage, and was too enthusiastic, moving right on the the sound sensor. ![]() A lot of lash, I will grant, but easy and cheap. I also must admit it is good seeing a sensible use for the 32072 - Technic Knob Wheel - a neat way to deliver movement at 90 degrees without the complication and non-compliance of a worm gear. It was a fairly simple build on top of the touch sensor Tribot, although having seen a version of this with the UltraSonic - the touch sensor seems a bit primitive. The Tribot with a grabber is one of the demonstrations seen in many of the images on the net in the run-up, along with Alpha-Rex (which I will be building later). Time to get started on adding a grabber to the Tribot.
