Students from a high school in Pozega went beyond the Buggy to create their own custom obstacle-avoiding line follower vehicle with four different click boards wired to a PIC18F45K22. It’s called the Gimbot.

Quite an elaborate project for a group of high-schoolers, Gimbot has been designed from scratch. It has two PCBs. The lower one carries the wheels, voltage regulators, lights, and two DC Motor clicks for independently controlling the left and right wheel (our own Buggy also relies on a differential drive). Additionally, a Line follower click hangs from the underside of the board.

The upper PCB carries the obstacle detecting Proximity click and a PIC18F45K22 as the central MCU. A 3.8V lithium battery is sandwiched between the two PCBs.

The young designers behind Gimbot are the same group we wrote about last year when we published a report from Gimfest, a student-organized local Science Fair.

Quite popular for a high-school event, the Gimfest Science Faire attracts thousands of visitors from the neighbouring cities and towns. Held for 8 years in a row, the students who organize the event are always doing their best to surpass last year’s Faire with more elaborate projects.

Last year the younger visitors were most attracted by the Buggy, so the team worked hard this year to deliver a custom line follower robot. And these are all after-school activities. That kind of zeal and persistence will lead to promising careers after graduation.

Yours sincerely,
