The UCTRONICS Smart Robot Car Kit is an easy to build obstacle avoidance robot kit that also allows for direct user control of the robot through either Infrared (using the included remote control) or Bluetooth (an Android App is available on the Google Play Store).

This is a great starter kit as no soldering is required and additionally there is a lot of space on the robot chassis for customization and additions later on. Assembly instructions are provided in full color and takes the builder through the assembly process in a step-by-step manner, which is easy to follow.
A prebuilt Arduino sketch is available for download from the UCTRONICS website to make the assembled robot functional, however nothing prevents the builder from writing their own. This is however one area where I do feel the kit falls short as an educational tool, instead of just providing a prebuilt sketch, it would have been great if a step-by-step guide was provided taking the builder through the process of writing their own sketch, explaining concepts and what is being done and why along the way.
This is however still a great starter kit and I would recommend it for anyone getting started in robotics or Arduino related building.
