Amblit Technologies purchased the Adeept PiCar Pro Robot Car Kit from Amazon in January 2022 for $169.50. A description of the kit can be found here. The kit has two (2) different configurations: pivoting head with camera and light or a robot arm with a simple gripper. Both can indepdendly assembled, but some disassembly and reassembly is required to mount either on the car chasis.
The car kit features four (4) wheel drive (i.e., a motor on each wheel), ultrasound for object avoidance and distance measuring, and video for object motion following, color detection and real-time video transmission. The robotic arm has three (3) degrees of freedom and can pick up small objects of up to 50 grams.
The kit requires a Raspberry Pi 4 Model B (includes Bluetooth) and must be purchased separately. You should purchase at the least the 2 GB RAM version. Prior to the pandemic the 2 GB version could be purchased for the $45 retail price. Given the chip shortage this computer has been difficult to find, but can now be purchased in several different retail outlets and Amazon in the $150 to $200 range.
The kit requires two (2) 18650 lithium ion batteries and charger which must be purchased separately. The video
