Since the initial release of the replica, a second version has been introduced, the differences being in the test program and the power switch. It is an updated version of Bigtrak, its form based on the Bigtrak Jr with the 'cockpit' modified to be much smaller and streamlined.

And we love SAM Labs wireless electronics components for making it easy for kids to make Internet of Things inventions. The original optional cargo trailer uses a single D cell battery to power its electrical motor, both for driving and dumping operations, while the optional rocket launcher accessory for the Bigtrak Jr uses 3 AA batteries. However, there was no provision for an accessory, and its motion sensor was based on a cheaper reed switch instead of an opto-isolator.Definitely a good introduction, but there's only so far you can go with a small set of commands and a limited number of instructions.

There is also a "repeat" instruction allowing simple loop to be performed, but the language is not Turing complete, lacking branching instructions; its programming also resembles the principles of turtle graphics from Logo programming language. It's also a great ice-breaker when children have friends around to play - it gets them up and playing instead of just wanting to use screens all of the time. The colour and graphic scheme are based on the UK version and all stickers have been redrawn as a direct copy of the original artwork.

This electrical isolation helps prevent electrical noise from the motor, speaker, and lamp from resetting or interfering with the microcontroller. The inspection was for speed, torque, and current consumption, before final installation into the product. It's a great feeling to be able to take a project from an idea in your head to a real object that does something. Meanwhile, in the 2000s and 2010s, many people have hacked the Bigtrak by allowing it to be controlled with modern microcontrollers such as the Arduino, or even a single board Personal Computer such as the Raspberry Pi. Kids can program it from the keypad to navigate courses around a room using motion and direction commands.

Robotics go back to the future with the retro looks of smash-hit 80s toy Bigtrak working together with high-tech smartphone technology.Our projects are tried and tested on our own kids or at events we run, so we are sure you can have a go at home with your kids.
