Introducing the Picobot and Agobo from 4Tronix

Many thanks to 4Tronix for sending me a Picobot and Agobo to review. Rather than making a video and reviewing straight away I have been using both robots at school with my Pi club for a couple of weeks.

If you are looking for a robot kit to get you into robotics both of these are great starting points.

The Picobot

The Picobot is a low-cost swarming robot costing £21.95 which comes ready assembled (just add wheels). It is rich in features and can be bought as a class set of 6 for swarming projects.

Features include (from 4Tronix website) and more details here.


I haven’t yet experimented with programming the Picobot but we had great fun at school designing different mazes for him to follow. This also gave a great introduction into line following algorithms.


The Agobo

If you are looking for a Raspberry Pi based robot I can definitely recommend the Agobo. You will need a Raspberry Pi model A+ and WIFI dongle in addition to the robot. I have been using the Agobo in a class situation and had 6 different groups of students logged into it writing simple control programs.  For more details and examples of worksheets check out the link here.

The Agobo is very easy to assemble and can built in a range of different configurations.

Features include (from 4Tronix website) and more details here.

The following optional extras are also available.

The Python library for the Agobo makes programming it very simple and I had a great response from the students at my Pi club when I introduced him. The students also had a look at how we could use the ultrasonic detector to make a simple crash prevention system. This gave me a great opportunity to introduce a simple always turn left if blocked algorithm. For £25 + the Raspberry Pi A+ makes this an affordable introduction to robotics and programming robots. The design is very sturdy and well constructed.
