With the rise of cheap embedded computers like the Jetson Nano
it is possible to build cheap and powerful educational robots that use ROS.
As part of my Graduation Project i have build a cheap educational mobile manipulator,
that can be useful for an introduction to the world of robotics.

It consists of
Jetson Nano (100) - TX2 (600)
4x Geared DC Motors with encoders (4x30 = 120)
arduino due(30) (with rosserial for pid speed and publish encoder ticks, it also reads the encoders directly)
1 ydlidar X4 (100-300)
1 kinect v1(50) - realsense(200)
3 dc-dc buck converters (30)
2 L298N(15) - sabertooth (60)
1 lipo 5000 mah (50)
1 I2c servo driver (20)
1 diy robotic arm (200) no feedback - with feedback (800…)
1 robot base could be just wood with metal rods to make 2 levels and motor brackets
total cost (cheap materials) ~~ 600
