This video demonstrates my "Gyro Controlled Robot Plotter".
The plotter comprises two 6 volt N20 DC motors, an SG90 servo, an HC-05 Bluetooth module, and a BNO055 sensor fusion module for turning.
The plotter algorithm is similar to "Join the dots" where the plotter turns to face the target then moves.
Circles comprise a series of straight line-segments. Providing the dots are closely spaced circles and arcs look smooth.
Full construction details and the Arduino code can be downloaded from https://www.instructables.com/member/lingib/instructables/ in the next few days.
