This gear driven Robot will drive forward until any of it’s three photo-sensors detects an obstacle in its path. The OARBOT uses 3 sets of on-board InfraRed Transmitters and Receivers which are aligned to detect obstacles in front and to the side of the Robot. Both the power of the InfraRed Transmitters and the sensitivity of the InfraRed Receivers are adjustable.
The large wheels feature rubber tyres that afford good grip on most surfaces.
This presents a most engaging learning experience for young minds as they can adjust several aspects of the sensors (including different reflective surfaces of the “obstacles”) and develop an understanding of how “inputs” can impact upon the behaviour of a “System”.
Imaginative minds have developed their own “Obstacle Courses” for their robots to try to navigate.
