Tentacle Insect


The tentacles are important tactile sensing organs of insects. In this case, we use limit switches and ultrasonic modules to simulate the tactile feedback and obstacle avoidance characteristics of insects.

Parts List:

Two limit switches, 3IO expansion module (5v) and other sensor modules, 9-hole aluminum parts and other mechanical parts, screws, nuts, gaskets and other hardware accessories


Assembly method:

Fix the limit switch to the left and right of the Mio chassis with a bent nine-hole aluminum piece, and install the ultrasonic sensor so that it faces forward.


Funny Mio:

Press the infrared remote control combination button to switch to the tentacle insect corresponding program. The tentacle insect move forward, and if there is an obstacle ahead, the obstacle avoidance procedure is performed. If there are no obstacles in front, continue driving; if the two sides touch the obstacle, they will automatically turn.

Scene application:

1. " tentacle insect " in the manual.

2. "Exploring the road pioneer" in the textbook.


1. Pay attention to the interface connection sequence between the sensor and the main board.
