    One of the simplest ways to make a mobile robot involves differential steering, where two wheels move at different speeds as needed to turn and a ball caster keeps it from tipping over. The MrK_Blockvader is an excellent take on this type of bot — demonstrated in the first clip below — featuring a nice blocky body comprised out of 3D-printed parts, RC truck wheels driven by tiny gear motors, and an integrated roller on its back.

    The MrK_Blockvader is controlled via an Arduino Nano, along with an nRF24 breakout that allows it to receive signals from a radio transmitter unit. The build includes LED lighting as well as a piezo buzzer for all the beeps and boops. It can also take advantage of various sensors if necessary.

    The eventual goal is to use the MrK_Blockvader in a network of robots, hinted at in the second video with a worker at its side.

    Arduino Mega is the brains of this ant-like hexapod

    Arduino Team — December 13th, 2018

    Six-legged robots are nothing new, but if you’d like inspiration for your own, it would be hard to beat this 22 servo-driven, 3D-printed hexapod from Dejan at How To Mechatronics. 

    The ant-inspired device features three metal geared servos per leg, as well as a pair to move the heat, another for the tail, and a micro servo to activate the mandibles.

    To control this large number of servos, Dejan turned to the Arduino Mega, along with a custom Android app and Bluetooth link for the user interface. While most movements are activated by the user, it does have a single ultrasonic sensor buried in its head as “eyes.” This allows it to lean backwards when approached by an unknown object or hand, then strike with its mandibles if the aggressor continues its advance. 

    As the name suggests, the hexapod has six legs but in addition to that, it also has a tail or abdomen, a head, antennas, mandibles and even functional eyes. All of this, makes the hexapod look like an ant, so therefore we can also call it an Arduino Ant Robot.

    For controlling the robot I made a custom-built Android application. The app has four buttons through which we can command the robot to move forward or backwards, as well as turn left or right. Along with these main functions, the robot can also move its head and tail, as well as it can bite, grab and drop things and even attack.

    You can see it in action and being assembled in the video below, and build files are available here.
