IOT-Based Sumo Robot Control Using Blynk Software

The sumo robot robot has been around since 1990, it was first intrudeced in Japan. Robot suno is also contested by rule that have the same weight. The sumo robot can be controlled remotely by utilizing bluethoot as a communication medium for maneuvering cpmmands on the robot. But using bluethooth has the disadvantage of short range. In this study utilizing iot to communicate between Android smartphones and robot. From the results of testing the connection on the nodemcu esp 8266 microcontroller has a speed of 4.6 seconds. Stepdown circuit test with 5 Vdc result, lippo 3 cell battery 12.54 Vdc test result. Bts7960 driver test result can rotate clockwise and conterclockwise. Manuver test result with the iot system with four commands made Blynk software robot can manuver on command, forward, backward, turn left and right.
