Creating the Mini Sumo Known as Seeker

A PIC16F877 microcontroller is used to control this stealthy and autonomous mini sumo called as Seeker which is packed with lots of power into a small size of under 3” high.

The design includes Micromo 1717 gear motors used as the motors which are powered by SN754410NE 1A dual H-bridge from Texas Instruments. Both the motors and the electronics are being powered by a single 9V NiMH battery. The standard R/C racing tires and wheels for street touring cars are used as the tires and wheels of this Seeker and the HVW Technologies Sharp GP2D12 analog sensors are used as the IR range-finders.

The chassis used does not have any wedge on the front but has room for a AAA 6-cell NiMH battery pack for running the motors. It is much more precisely machined as the RF telemetry board is seen attached to it. The board is a simple dual perfboard that has the SC transceiver RF module from Linx mounted on one side and on the other side is the PIC16F876 microcontroller. The power, ground, serial I/O, and a presence indicator are included in a 4-wire connection to the board.
