Design and Prototyping of an Automatic Robotic Buttons/Keypads Pusher On Prepaid Electricity Meter for Automatic Tokens Keying
Budget: $30 – $250 USD
The device is a wireless IoT device which has robotic button pusher module with pushing arms in conformity with the prepaid meter buttons patterns arrangement on a meter cover.
The device should also have a sensor module to Real-Time Detecting and Reading of the meter LED/LCD display screen. Generally the device should be able to archive the following:
1. Be able to receive meter recharge tokens from the cloud through IoT com channels it has
2. After receiving the tokens, quickly receive the signal from the sensor module after reading the meter display screen. If the meter is ON:
(a)then the pushing buttons will push the meter keys one by one while receiving the correctness feedback of the numbers keyed in from the screen sensor and finally read the new balance of the meter and that the process is successful. All these should be done locally there, after everything, the final result is sent back to the cloud for recording and other decisions if any.
If meter is OFF (is determined when the screen sensor return blank):
(b)The token will be stored locally in the device and retry to input again once the power is back
NB: If there are many tokens stored which failed earlier, and power is back on the meter, then will be retried to be keyed in the meter on the FIFO basis.
3. The device should be power by itself for as long as possible. Possibility of rechargeability also possibility of being recharged from the host meter.
4. The robot device should be able to fit around various prepaid meters formarts.Fixing on the meters should be by very strong adhesive mounting
5. Able to communicate with the cloud using very low energy IoT connectivity
