How to go about buying a new robot?

Considering buying a new robot toy? But there are so many to choose from! In this short article, we outline how to choose one in under 15 minutes! First, you need to consider what exactly you have in mind. There are many different robots and building kits out there and some may be too expensive, too cheap, too difficult or too easy for you. Do these 3 easy steps to get the best robot for you or someone else!

1. Who is the robot for?

Are you buying to someone who is already skilled in programming? Or is this a gift to your nephew who is yet to build his first robot? Consider this as you choose. There are robots of all dificulties out there. There are lego robots, buildable robotic kits, robots that already come assembled, programmable robots or combinations of these. If you’re buying the robot for yourself, try to read descriptions of the actual robots or ask in communities. You can even reach out to manufactureres! If you’re buying it for someone else, try to think about what they might like. If they are more of a hands-on engineering type, a buildable robots with simple controls might be the best choice. If they’re more tech savvy and like programming, there are robots just for that! You can discover more about robotics choices for robot building

 2. Check the price

You can easily pay 500$ for a robot. And you can easily get one for 50 that doesn’t work as he is supposed to. It is of course natural that more difficult robots with more functions are more expensive. So what is the ideal range? It depends on the age of the person who’s going to be using the robot and their skills. When it comes to me, I wouldn’t spend less than 70-80$ for a robot but I wouldn’t really go over 400$ either. You can get good programmable robots with many functions for 200-300$.

3. Consider other factors

I have a friend who has three children. One of them, a boy of 12, wanted a robot last Christmas. The other kids didn’t seem interested in robotics and wished for other toys. But as soon as they saw the robot walking around on Christmas morning, all they wanted was their own robot, for which, of course my friend didn’t have money for that and the kids already had other presents anyway. In the end, trying to be  good parent, he said to his son to lend his new robot toy to his siblings. This of course didn’t suit well with the boy, since his siblings got toys of their own for Christmas. Before buying an expensive thing like a robot for your children, make it clear to them that they need to share the toy or make up their minds about it beforehand. Another thing to take into consideration are pets who might get scared of the walking mechanical toy and possibly damage it.

If you are still uncertain about what to get, feel free to browse other blogs.

RSGEX Module

RSGEX Description

The RSGEX Dual Switch Controller is high current switch controller compatible with most R/C receivers. The controller provides two open-collector outputs which can be used to operate relays, solenoids, valves or just about any weapon hardware. Since it is completely solid-state, there are no moving parts to fail during combat as with linkage mechanisms connected to servos.


  • Opto-isolated R/C Channel Input
  • Built-In hystersis input insure no false triggers
  • Automatic Detection of R/C Signal Loss
  • Dual Independently Controlled Outputs (either normally open or close)
  • Each Output is rated to 60V, 3A
  • Runs off 12V.


Pricing: $39.00

A great module for your fighting robot is sometimes all it takes

RSGTX – the best motor out there

RSGTX Description

The RSGTX is a dual motor controller and comes fully assembled. This controller is RSG’s third-generation motor controller. It’s small and comes in a tough extruded aluminum case. The controller interfaces to standard R/C receivers. Two mixing options are available, plus a third channel and/or SPST input for reversing or swapping motor outputs if your robot is flipped. Over-current control logic prevents meltdowns and provides the maximum current even under stalled conditions.

RSGPX review


The RSGPX is a combination of a receiver battery eliminator; a RSGEX, dual switch controller, and two adjustable power supplies all in one package. The RSGPX removes the need for a separate battery for the R/C receiver and any other accessories your robot may require.The RSGPX comes fully assembled. Like the RSGEX, the RSGPX, interfaces to standard R/C receivers.


Built-In hystersis input insure no false triggers
Automatic Detection of R/C Signal Loss
