We have developed a wheeled mobile robot.
It has an arduino grand central with shield, raspberry pi with screen , gps stack and power module mounted on an 12 by 9 inch plate. Other sensors are also connected into the grand central. IMU(serial), encoders (digital) , current voltage sensors (Analog).
We want the option to mount sonar (Analog) and Lidar (I2C)
The wiring between the modules and sensors needs to be improved to reduce the chance of mechanical stresses breaking the connections. The robot is all electric so engine vibration is small
The project is well supported with documentation. We would err on the side of robust and simple rather and complicating the design to produce an all singing/dancing solution. It can always be improved
Please only reply if you are a qualified electronics engineer and have excellent English communication skills. Dur to the time lap please also only apply if based in the USA or Europe
More information can be supplied after initial screening
