Wheeled Robot Chassis : Buying & DIY Guide

Normally Wheeled Robot Chassis Are Sold Separately and Also Can Be Custom Build. Here is a Buying cum DIY Guide For Wheeled Robot Chassis. We already talked about Arduino powered robots, how to choose 3G module to make it wire free, difference between Arduino and Raspberry Pi boards.

 

Wheeled Robot Chassis : Basics on the Platform, Mechanical Stability etc.

 

3D printed Wheeled Robot Chassis is great for testing purpose unless you are going to build a toy. By definition, wheeled robots are robots which are mobile and can navigate around the ground using motorized wheels. This design is simpler than using treads or legs for movement in flat terrain. Disadvantages of wheeled robots mainly is that they can not navigate over surfaces like rocky terrain or surfaces with low friction. Wheeled Robot Chassis can have any number of wheels, but three wheels are sufficient for basic static and dynamic balance. Additional wheels can add to balance.

We would suggest to think about metal tracked chassis if project is going towards uneven surface. Movement can be complex for tracked chassis despite the advantages.

Two wheeled robots are difficult to balance than more wheeled. Two wheeled robots are known as swing-type robot. 3-wheeled robots can be differentially steered (third wheel is free rotating wheel to keep the balance) or 2 wheels powered by a single source and a powered steering for the third wheel. The second one is better when 3-wheeled is chosen for Wheeled Robot Chassis. Most commonly the new buyers get fooled at this point. 4-wheeled Wheeled Robot Chassis follows car body’s principle. Normally â…“rd of the weight (which is length for normal plate) can be cantilevered. When there will be need of protruding more than â…“rd of the weight, some counter mechanism should be added to balance, else the thing may fall & adult morons may laugh like kids without knowing a single line of coding.

 

Wheeled Robot Chassis : DIY is Not Great Option

 

Basically the build quality of factory made metal Wheeled Robot Chassis tend towards a sturdy, well balanced designed to ensure safety of the main robot which will do certain action after movement. If there is robotic arm to perform an action, gear becomes mandatory for parking. Basic mechanics of a Wheeled Robot Chassis is exactly like a car. Custom build is better phrase than DIY for these works as custom build usually not for limited budget but for limited availability of the desired design in the consumer DIY market.

 

Wheeled Robot Chassis : Current Market Rates

 

Tamiya is a well known name. Plastic made Tamiya Tracked Vehicle Chassis Kit costs $16.00. It is quite basic but possibly great as there are many guides on the web for Arduino and Raspberry Pi. Crawl Space Inspector FPV, for example are for better control and have sturdy body. They will cost more than $500. If you searching for better build, search with Alloy Wheeled Robot Chassis.

Moving is definitely a hard work and needs huge debug, real life checking; but basically the main thought will revolve around, what exactly it will perform. We will also suggest to think about RC Crawler Truck instead of only buying the chassis. Sometimes kids buy them & their parents sell them not for helping us but for SAVING the kids’ normal time needed for reading. As these have the support for spare wheels, springs, gear etc. basically they are better in long run, however the work needed is huge.
