Hi!
I was hoping you can help me out. I am looking for a wheeled robotic chassis that is prebuilt and has the following capabilities:
• 3 or 4 wheels with approximately 4-6-inch wheel base that can move over soft or hard surface.
• Robot will move in a random pattern but will stay within the bounds of printed box that has a colored line on the boundaries. I would envision a sensor on the robot that can detect a solid line and turn away from the line. I would also like the robot to have the ability to travel in a preprogrammed pattern.
• Would like to control the robot with a smart phone
• Bluetooth type speaker on the robot that can play music from a local smart phone.
• Have a mechanism on the robot that can drop or push a small object off the robot at a predetermined or random time.
• The chassis only needs to carry up to 3-4 pounds on it.
• Rechargeable battery that can last at least 2-3 hours and can be recharged using a USB port.
I am not an expert on the capabilities of robots so any assistance you have on designing and building this thing is greatly appreciated.
Regards - and thank you so much in advance for your help!
I took a look at it and found some robots you might be interested in, like these:
The raspberry pi based robot cars are great solutions because you could simply add more modules and sensors if you need them. For the colored line bounds a line sensor would be great, some of the options I mentioned already include it, but you could add one or use a camera for that.
For grabbing objects you could add a gripper or depending on the objects you could simply add some brackets as arms for pushing.
There are also many other robotic platforms available but I thought those were some nice options because of the dimensions you mentioned and for the ease of adding modules to the project.
Finally, I recommend you read the How to Make a Robot tutorial series and check the Robots section for some inspiration where you can also share your robot
