There are different kinds of waste that affect our environment, for example metallic and plastic waste. Developing metallic waste collection robot system is mighty challenge. There is very limited research related with robot systems that specialize in the collection and processing of waste. In these slides, we propose robotic system that can be used for waste metallic collection. This robot is equipped with metal detector, ultrasonic sensor, control and power unit, and actuators. This autonomous robot can perform tasks such as obstacle avoidance and metal detection. . Chemical bonding. Chemical Bonding. Diamond. Silicon dioxide. Graphite.
