open source weed killing robot

Here's a little robot I'm working on to use personally and will share openly.

I have built this to do task like floor cleaning , or UV disinfecting, among other things . the current proto-type is remote controlled , but future versions will be automated.

This guy is intended to drive the snowblower and a lawn mower , as well as a salter and some other outdoor automation attachments. 

an early robot playing with tpu tracks , needs some work, was originaly an fpv spy robot, toy sort of thing .

yet to be finished and programmed , but physically it is finished . someone was selling the plans for this and i just made it up from the pictures .

My first 3d printed robot that I played around with the sonar sensor and obstacle avoidance .
