An apparatus and a method for performing direct communications between vehicles over a cellular vehicle-to-everything (C-V2X) communication protocol includes for each sub-frame in time domain that has a first number (N) of sub-channels in frequency domain, identifying a second number (M) of vehicles, each vehicle of the M vehicles having a packet to be transmitted during the sub-frame. The method includes determining a remaining time in a delivery deadline of the packet to be transmitted. The method includes estimating a transmitter-receiver distance between the vehicle and a corresponding receiver vehicle at an end of the sub-frame. The method includes identifying 2N vehicles from the M vehicles, based on the remaining times and the transmitter-receiver distances. The method includes pairing the 2N vehicles into N transmission pairs that correspond to the N sub-channels, to maximize a sum of interference distances of direct communications over the N sub-channels.

A line-following robot in an assembly line. The line-following robot includes a microcontroller, a camera connected to the microcontroller, disposed on a front of the line-following robot, and configured to collect line images, an Infrared (IR) sensor array connected to the microcontroller, disposed on the line-following robot, and oriented in a direction of travel of the line-following robot, a first wheel set and a second wheel set disposed opposite one another on opposing sides of a bottom of the line-following robot, and a battery. The microprocessor controls a motor speed of the line-following robot based on an upcoming assembly line by continuously capturing and processing the lines images using an advance image processing technique and computer vision techniques.
