[Eduard] chose the latter, and also included obstacle avoidance sensors in the process. We’ve seen quite a few that use these ultrasonic rangefinders.

It also carries an LM293D motor controller and [Sath02] added an XBee module for wireless control. At the top of the assembly is an IR distance sensor which is used for obstacle avoidance.

While child-sized humanoid robots like the Unitree R1 have come down in price, not everybody has a spare $6,000 to throw ...

The ultrasonic sensor detects the surrounding objects and sends the data to the Arduino Nano. When an obstacle is within a certain range, the Arduino Nano activates the buzzer and haptic motor.

Smellicopter can also avoid obstacles with the help of four infrared sensors that let it measure what's around it 10 times each second.
