Also pretty badass at the same time! The Raspberry Pi is powered using a USB Rechargeable Power Pack, in my case I used an EasyAcc 10000mAh pack which when fully charged last for ages (not a technical unit of measure but you get my drift). There was a problem. The Arduino, is simply used to control the motors of the robot. This is a high initial outlay but is a one off cost. The web page that I created contains a simply control panel with buttons marked Forward, Backward, Left, Right and Stop. When the robot itself is turned on the Nano fires up and starts to listen for commands coming in over the i2c interface from the Pi (when a button is pressed on the web page control panel). DonkeyCar … The rover has three main abilities: localization to find its current location, navigation to determine an optimal path to travel and locomotion, which moves the rover along a predetermined path. Control over the web interface needs further work, clicking on a control button on the web page control panel (a .html mouse down event) causes the robot to move, there is too much delay between sending the stop command (the mouse up event when the user releases the mouse button) and the robot stopping the current command. Following a course about autonomous cars in CentraleSupélec in France, we had a self driving car challenge in which I, along with a small group of my friends, programmed a Cherokey 4WD … Making the rover mobile is a 6000 mAh battery.
