features:

programs

• programs for access the vehicle over the internet
  • program for controlling motors
  • program for videostreaming
• open-source software, all programs written in python (focus on easy to understand)
• programs using udp for low latency
• opencv for taking video and displaying them, good for future AI
• all programs can as well be used for standard rc-cars, airplanes or boats with PWM input and even for stationary surveillance cameras.

3d printing

• open-source hardware, hole car 3D-printable
  • 3D-printed ball bearing (printable in one piece without any support)
  • 3D-printed flexible tires (airless, filaflex 82A)
• insertable metal springs on all axis
• assembly with only M3-screws and threaded brass inserts
• support structures rarely required, low part count, easy assemply

electronics

• two individual servomotors to steer the front wheels
• two individual brushless motors directly integrated into the rear wheels (inwheel, hubmotor)
• raspberry pi
• blheli32 ESC's (will soon change to B-G431B-ESC1)
• 18650 li-ion cells with bms (25.2V)
• low cost

disadvantages

• low torque cause of directdrive hub motor (will increase with planetary gear)
• low torque cause of sensorless ESC (will increase with currentsensing ESC)
• video stream consumes too much data
