Hi. Absolutely new to Robotics. Have a chassis with tracked drive. Am thinking first of developing some system of obstacle avoidance. In this connection, using a relatively cheap system of I/R Transmitter and I/R Phototransistor, I need to know if the I/R beam from the Transmitter will bounce or reflect from obstacles, so enabling the beam to be detected by, say, a Phototransistor seated inside a conical reflector. What would be the state of this reflectance from soft surfaces, curtains, furniture, etc, compared to hard reflective surfaces? Is this a viable scheme for the purpose intended? Love to hear from someone who has investigated this mode. Thanks. Walt.
