altered the feet so he could walk in grass, as well as adding a charging pad in the feet so he could walk to his charging dock and initialize his own charging routine. He's powered using a mini beaglebone. As soon as I give him an us sensor, he will be acid to begin making mapping hid environment. he plays fetch, walks around the house, and beeps and boops when you interact with him. easiest and most difficult pet I've ever had.
