RoboStreet One (R1) — Class 8 Electric Robotic Cab & Chassis

Product Definition

R1 is a chassis platform — not a garbage truck

Refuse collection is one of the first flagship applications, but it does not define R1's product boundary. From day one, R1 treats the vehicle as a mobile robotic platform: the chassis handles safe motion and energy supply, the upfit handles the industry mission, and autonomy plus Street AI handle mission understanding, coordination, and the operational loop.

⚙️

Original Platform

Cab, energy, by-wire control, upfit interfaces, and intelligent coordination designed together as one vehicle.

🧩

Module Reuse

A standard mounting grid and electrical / data interfaces adapt the same chassis to many upfits — no reinventing vehicle control per model.

🛣

Evolution Path

Human driving, driver assistance, and ODD-limited driverless operation share the same physical foundation.

Platform Overview

One chassis, six key systems

R1's advantage is not a single component — it is the combination of systems in one vehicle architecture. Watch the functional zones light up in sequence.

🚐

Mobile Cab

Lateral seat position + full-cab lift + front boarding — covering both traffic directions and improving frequent entry/exit.

SYS

🔋

Energy Spine

400/600 kWh LFP fully hidden under the frame — freeing side space, lowering CG, protecting the battery.

SYS

⚙️

Axle Drive

Direct e-axle output with regenerative braking — efficient, precise at low speed, fewer mechanical links.

SYS

🔌

Intelligent Interface

By-wire, sensors, compute, and robot safety interfaces — supporting autonomy, manipulators, and multi-device coordination.

Energy & Motion

800 V · 1.2 MW · hidden LFP

A unified energy and motion platform for high-utilization heavy missions. The battery lives inside and under the frame rails as a structurally protected under-frame energy spine — no bulky side battery boxes, leaving room for upfits, tools, pneumatics, cooling, and robot interfaces.

400

400 kWh LFPUrban sanitation, campus logistics, airports, fixed routes with opportunity charging

600

600 kWh LFPDouble shifts, ports, utilities, and high-load missions

MCS

1.2 MW fast chargingLiquid-cooled high-power interface; actual power depends on battery version, SOC, temperature, and infrastructure

PTO

Electric ePTOManaged high power for compactors, hydraulic pumps, manipulators, and external tools

800 V

Traction HV bus — traction, charging & ePTO in one architecture

1.2 MW

Peak platform charging input

≈500 kW

Continuous drive power target (≈800 kW peak)

125/250 kW

ePTO continuous / peak target

1.2 MW is peak platform capability, not sustained across the whole charge curve — validated after cell, cooling, and infrastructure freeze.

Intelligent Vehicle

Full by-wire makes the chassis a controllable robot

By-wire scope covers propulsion, steering, brake request, parking, gear, regen, cab slide/lift, bumper platform, ePTO, and upfit permissions. Safety-critical actions run on deterministic on-vehicle controllers — cloud and generative AI never enter the steering and braking loop.

✅

One Ready

Full by-wire, sensor & compute mounts, time sync, data logging, and remote diagnostics.

🤝

One Assist

AEB, surround view, blind spot, auto parking, curb approach, and low-speed work assistance.

🤖

One Autonomous

Driverless operation inside validated and approved ODDs, with minimal-risk-maneuver capability.

Robotics & Collaboration

The robot is a mission module, not an accessory

Manipulators, compactors, tool modules, and mobile robots connect through independent safety controllers. Upfits can read vehicle posture, speed, parking, load, and personnel-zone state — but can never bypass the vehicle safety domain to control steering or braking.

robostreet one rs1 — the R1 platform as a robotic refuse truck: the mission module's arm grasps, lifts, and loads while the vehicle safety domain holds e-stop, park permission, and personnel zones.

Human + Global Design

One cab, many markets and work positions

The cab slides between left, center, and right locking positions. The same chassis base serves US/EU left-hand-drive and UK/AU right-hand-drive markets; in sanitation or field work the operator can choose the side closer to the curb or work zone.

Design intent: fewer left/right-drive SKUs, better sight lines, and better ergonomics for high-frequency entry/exit missions like refuse collection, utilities, and airports/ports.

Applications

The garbage truck is just one case

The product core is always the scalable cab-and-chassis; industry vehicles are defined by upfits and software mission packs.

Industry	Representative upfit / mission	R1 platform value
Municipal & Waste	Rear/side loaders, sweeping, robotic collection	Low entry, stop-start regen, ePTO, manipulator coordination
Campus & Logistics	Box, flatbed, tractor, fixed-site milk runs	Closed routes, unified dispatch, opportunity charging
Utilities & Field Service	Tool bodies, cranes, manipulators, mobile power	On-board energy; crew / tools / robots as one system
Energy & Frac Sand	Sand tankers / tractors, private-road convoys	600 kWh, high payload, site autonomy & fleet coordination
Airports & Ports	Low-speed special upfits, cleaning, yard transport	Zero emission, geofencing, high utilization, remote supervision

First R1 engineering-validation vehicles are integrated on a Nikola Tre BEV chassis. This describes the early prototype path only — it does not change R1's definition as a RoboStreet original cab-and-chassis vehicle. RoboStreet maintains independent model configuration, BOM, software versions, test records, applicable-standards matrix, and emergency-response documentation for R1.
