For someone interested in mechatronics, this tree climbing robot would be a great project to attempt. The tree climbing robot uses two segments, one which attaches to the tree and another which continues to climb upwards after which they swap roles, slowly edging the robot up the tree. The result is surprisingly effective and very satisfying to watch! To find out more check out the following link or the video below.
When you use motors in your Arduino project you will almost certainly need a H-Bridge motor driver. A H-Bridge allows you to easily control the direction of your motors from within your code. Our own Dual Channel H-Bridge Motor Driver Shield is a perfect solution to this problem, allowing you to drive two DC motors or a stepper motor.
The Dual Channel H-Bridge Motor Driver Shield features PWM control, selectable current limits and a prototyping area to add your own parts. To find out more check out the Dual Channel H-Bridge Motor Driver Shield page.
