The beginnings of Deathball, the 60mph sphere robot

This is the sphere robot I've been working on for the past few months. The plan is to make it be able to do 60mph, which is kind of a scary idea.

Update January 7th, 2020.

Samsung just showed off their new Ballie robot at the Consumer Electronics show in Las Vegas. Ballie is a new personal assistant sphere robot, and looks pretty cool, but can it do 60mph (97kmph) like my sphere robot "Deathball"? I very much doubt it. Deathball will smash Ballie into a million pieces, if your dog doesn't first.
