The most important factor to consider when choosing the best robot is whether the robot performs the function you want it to perform. You might be considering a purchase of one or more mini robots or you might be trying to judge the best mini robot for a contest or article. Whatever your reasons for choosing the best mini robot, you need to set the criteria, then match the available robots to them.
First, decide why you need the robot. If it is for fun, then you know you only have to look for toy robots. If you need a small robot to explore a small space or to perform a function such as repairing something, then you can narrow down your search by ignoring robots that do not perform this function. Furthermore, you can narrow down your options by removing those that are too big or too small.
Know your budget and know how many robots you want to buy. Naturally, if you want to buy only one robot, then you can probably afford a more expensive model. If, on the other hand, you need to buy a number of robots, then naturally, you are going to have to divide your budget by the number of robots. While looking at budgets, also remember to look at the delivery costs of robots, as this will have to be factored in as well.
Once you have a short list, ask friends, relatives and co-workers who might have had experience with buying and using a mini robot for their advice. Bear in mind that their personal experience might not be indicative of the mini robot company as a whole and their use of the mini robot might not mirror the one you have in mind. If no one you know has had such experience with the companies on your shortlist, then do not worry; there are other options available to you to help you make an informed decision.
Most companies are only too happy for you to visit their shop or factory so you can see their mini robot in action. By seeing the robot perform its function, especially if you can get the company to make the robot perform the function you want done, you can make a decision over whether the mini robot is suitable and if it is cost-effective. On the other hand, you can also cross robots off the list that do not perform the task well.
When making a purchase of a mini robot, you might not make the right purchase the first time out. This need not be a waste of money. Just make sure the company has a quality guarantee, a product warranty and a return policy. It is especially important to have these guarantees if the company has not let you test the mini robot first.
