These robots run $100 - $150 each as opposed to the Mindstorms $250+ (now $350) price point. &amp;#60;&amp;#60;&amp;#60;&lt;p&gt;I have tested the Parallax Sumo bots and Mindstorms and I&apos;m firmly of the opinion that the Mindstorms set represents better value.&lt;p&gt;The thing is that at the end of the day the Parallax Sumo bots are one trick ponies and have a fixed chassis and configuration around which you really can&apos;t extend without some effort. Even if you do put in the effort, then your design is constrained by the type of chassis the machine came with. For example, you can&apos;t easily convert the sumo bot into a hexapedal or bipedal walker. The value proposition for these machines rests solely on programming them in beautiful ways and it really isn&apos;t possible for a child to extend the machine itself. Assemble it yes, but it extend it? Not yet.&lt;p&gt;On the other hand with the Mindstorms set you have these precision milled parts that can be combined in endless ways by anyone to create anything from walkers to holonomic drives. There&apos;s also the benefit of the entire Lego range, you can easily mix and match all of these parts and combine them in countless ways with one another to give you literally any type of machine you want without getting out a file or a drill. That&apos;s something that instantly appeals to children and I remember the amazing feeling I used to get out of playing with Mindstorms when I was a little girl. I could actually create something that was &quot;alive,&quot; and there was nothing better than that. Programming seemed dull and useless to me as compared to putting these pieces together and bringing them to life, somehow. It was captivating and it&apos;s what gave me the real push towards actually learning engineering. That&apos;s a miracle if you think about it and it represents great value.&lt;p&gt;&amp;#62;&amp;#62;&amp;#62; There is a huge untapped market for a programmable robot at the $50 - $100 price point. &amp;#60;&amp;#60;&amp;#60;&lt;p&gt;It&apos;s actually quite easy to build something yourself at that price point. Get $3 DC motors, waste aluminium channelling from build sites, acrylic, gear boxes + wheels, wires, an arduino, and a few screws. Build a frame out of the channelling, use the acrylic sheets as a type of wall, drill and mount motors on the acrylic sheets and put the arduino on somewhere with pencil cells. You&apos;re good to go.</text></comment>
