Avaliação de LoRa para controlar um braço robótico de forma remota em uma cidade típica da Amazônia

This work evaluates LoRa technology to remotely control a robotic arm in Marabá City, which has wooded areas with trees up to 12 m high and suburban buildings. The arm is a prototype built with MDF pieces, capable of performing eight movements. The measurement campaign shows that without a line of sight, the arm was remotely controlled at distances of up to 500m. These results exhibit that LoRa technology, even with a narrow bandwidth, is a great alternative to control over long distances.
