i am using a raspberry pi. My robot needs to be controlled from a website that can both send information and receive it without constantly refreshing the page. The robot also has to take this information and use it to calculate its current position a lot like how dead reckoning works. The robot has two motors with four ultrasonic sensors covering the front, back, and sides of the robot. It also has 2 DC Motors that control the wheels. The way I see this going is to have a website where you can use was to move the robot, by clicking on an arrow. I want 1 website that lets you control the robot while also giving you the readings of the ultrasonic sensors and its position, and should be able to input a destination that the robot will go to. Then the raspberry pi would receive the information from the website and then move the robot while also using the ultrasonic sensors to avoid obstacles and calculating its position.
